exa

exa is a modern replacement for ls.

README Sections: Options — Installation — Development

---

exa is a modern replacement for the venerable file-listing command-line program ls that ships with Unix and Linux operating systems, giving it more features and better defaults. It uses colours to distinguish file types and metadata. It knows about symlinks, extended attributes, and Git. And it’s small, fast, and just one single binary.

By deliberately making some decisions differently, exa attempts to be a more featureful, more user-friendly version of ls. For more information, see exa’s website.

---

Command-line options

exa’s options are almost, but not quite, entirely unlike ls’s.

Display options

• -1, --oneline: display one entry per line
• -G, --grid: display entries as a grid (default)
• -l, --long: display extended details and attributes
• -R, --recurse: recurse into directories
• -T, --tree: recurse into directories as a tree
• -x, --across: sort the grid across, rather than downwards
• -F, --classify: display type indicator by file names
• --colo[u]r: when to use terminal colours
• --colo[u]r-scale: highlight levels of file sizes distinctly
• --icons: display icons
• --no-icons: don't display icons (always overrides --icons)

Filtering options

• -a, --all: show hidden and 'dot' files
• -d, --list-dirs: list directories like regular files
• -L, --level=(depth): limit the depth of recursion
• -r, --reverse: reverse the sort order
• -s, --sort=(field): which field to sort by
• --group-directories-first: list directories before other files
• -D, --only-dirs: list only directories
• --git-ignore: ignore files mentioned in .gitignore
• -I, --ignore-glob=(globs): glob patterns (pipe-separated) of files to ignore

Pass the --all option twice to also show the . and .. directories.

Long view options

These options are available when running with --long (-l):

• -b, --binary: list file sizes with binary prefixes
• -B, --bytes: list file sizes in bytes, without any prefixes
• -g, --group: list each file’s group
• -h, --header: add a header row to each column
• -H, --links: list each file’s number of hard links
• -i, --inode: list each file’s inode number
• -m, --modified: use the modified timestamp field
• -S, --blocks: list each file’s number of file system blocks
• -t, --time=(field): which timestamp field to use
• -u, --accessed: use the accessed timestamp field
• -U, --created: use the created timestamp field
• -@, --extended: list each file’s extended attributes and sizes
• --changed: use the changed timestamp field
• --git: list each file’s Git status, if tracked or ignored
• --time-style: how to format timestamps
• --no-permissions: suppress the permissions field
• --octal-permissions: list each file's permission in octal format
• --no-filesize: suppress the filesize field
• --no-user: suppress the user field
• --no-time: suppress the time field

Some of the options accept parameters:

• Valid --color options are always, automatic, and never.
• Valid sort fields are accessed, changed, created, extension, Extension, inode, modified, name, Name, size, type, and none. Fields starting with a capital letter sort uppercase before lowercase. The modified field has the aliases date, time, and newest, while its reverse has the aliases age and oldest.
• Valid time fields are modified, changed, accessed, and created.
• Valid time styles are default, iso, long-iso, and full-iso.

Manual installation from GitHub

Compiled binary versions of exa are uploaded to GitHub when a release is made. You can install exa manually by downloading a release, extracting it, and copying the binary to a directory in your $PATH, such as /usr/local/bin.

For more information, see the Manual Installation page.

Cargo

If you already have a Rust environment set up, you can use the cargo install command:

cargo install exa

Cargo will build the exa binary and place it in $HOME/.cargo.

To build without Git support, run cargo install --no-default-features exa is also available, if the requisite dependencies are not installed.

---

Development

exa is written in Rust. You will need rustc version 1.66.1 or higher. The recommended way to install Rust for development is from the official download page, using rustup.

Once Rust is installed, you can compile exa with Cargo:

cargo build
cargo test

• The just command runner can be used to run some helpful development commands, in a manner similar to make. Run just --list to get an overview of what’s available.

• If you are compiling a copy for yourself, be sure to run cargo build --release or just build-release to benefit from release-mode optimisations. Copy the resulting binary, which will be in the target/release directory, into a folder in your $PATH. /usr/local/bin is usually a good choice.

• To compile and install the manual pages, you will need pandoc. The just man command will compile the Markdown into manual pages, which it will place in the target/man directory. To use them, copy them into a directory that man will read. /usr/local/share/man is usually a good choice.

• exa depends on libgit2 for certain features. If you’re unable to compile libgit2, you can opt out of Git support by running cargo build --no-default-features.

• If you intend to compile for musl, you will need to use the flag vendored-openssl if you want to get the Git feature working. The full command is cargo build --release --target=x86_64-unknown-linux-musl --features vendored-openssl,git.

For more information, see the Building from Source page.

Testing with Vagrant

exa uses Vagrant to configure virtual machines for testing.

Programs such as exa that are basically interfaces to the system are notoriously difficult to test. Although the internal components have unit tests, it’s impossible to do a complete end-to-end test without mandating the current user’s name, the time zone, the locale, and directory structure to test. (And yes, these tests are worth doing. I have missed an edge case on many an occasion.)

The initial attempt to solve the problem was just to create a directory of “awkward” test cases, run exa on it, and make sure it produced the correct output. But even this output would change if, say, the user’s locale formats dates in a different way. These can be mocked inside the code, but at the cost of making that code more complicated to read and understand.

An alternative solution is to fake everything: create a virtual machine with a known state and run the tests on that. This is what Vagrant does. Although it takes a while to download and set up, it gives everyone the same development environment to test for any obvious regressions.

First, initialise the VM:

host$ vagrant up

The first command downloads the virtual machine image, and then runs our provisioning script, which installs Rust and exa’s build-time dependencies, configures the environment, and generates some awkward files and folders to use as test cases. Once this is done, you can SSH in, and build and test:

host$ vagrant ssh
vm$ cd /vagrant
vm$ cargo build
vm$ ./xtests/run
All the tests passed!

Of course, the drawback of having a standard development environment is that you stop noticing bugs that occur outside of it. For this reason, Vagrant isn’t a necessary development step — it’s there if you’d like to use it, but exa still gets used and tested on other platforms. It can still be built and compiled on any target triple that it supports, VM or no VM, with cargo build and cargo test.

exa's Issues

Why use "=>" for symlinks?

exa is much nicer than ls and even ls++, but the use of "=>" confuses me on first sight. ls uses "->" to denote the destination of a symlink. So does rsync. And "=>" is used by rsync to denote hard links. So why doesn't exa take this convention?

Compiler error index out of bounds

Hi, I just wanted to try out exa on my mac and compile it with cargo build. The following compiler error happened when I tried to build it with the new alpha2 Version of Rust.

   Compiling datetime v0.1.4

Could not compile `datetime`.

looks like the datetime dependency does not work. Is this a bug with the rust compiler or is it something you can fix? I am completely new to rust and have no idea :)

On the -T option

Playing with the (amazing) tree view, I've noticed a couple of places for improvement:

• There is no Git information in this view.
• It says Option --tree is useless without option --recurse. I think we could imply --recurse then.
• It may be useful to pass an argument to -T limiting the nesting level, similarly to tree -L 2.

Panic using option --long when built without default features

When building exa with --no-default-features and running exa with --long it panics.
rustc 1.0.0-nightly (123a754cb 2015-03-24) (built 2015-03-25)

Don't print ANSI codes unless the STDOUT is a PTY

For example, if I execute a command

exa -l > output.txt

I don't want the file to contain the codes. It's even semantically improper: the codes should send control commands to the terminal, and if there is no terminal on the other end, there is nothing to control.

Build fails.

Should respect terminfo.

Currently, for example, set_a_foreground is always an ASCI sequence appropriate for xterm-color, even if my terminfo entry has a different one.

To verify:

# Create a terminal info copy. 
infocmp -L xterm-256color > my-term.ti
# Change its name and color attribute.
sed -i.bak 's/xterm-256color|xterm with 256 colors/my-term|My Terminal/' my-term.ti
sed -i.bak -E 's/([[:space:]]+set_a_foreground=).*/\1smth/' my-term.ti
# Compile it
tic my-term.ti
# Set the current terminal emulator to use the newly compiled terminfo.
export TERM=my-term

exa

It must print smth instead of colors. If you replace exa in the last command with, say, vim, you'll see the difference. I'd recommend you to take a look at the tput command.

Provide releases?

I realize that cross-compilation is difficult at this stage of the game, but it would be nice if compiled binaries were provided for whatever platforms are feasible for the author/contributors. Since there are 24 crate dependencies (when transitives are counted), it is likely that one or more crates will not compile at any given point in time. (In particular, at the time of this writing, libssh2-sys is not compiling.)

exa is not available on Windows

You mentioned you don't have a Windows machine, I do, I tried to compile exa (without git, for now) and it looks as if a couple of types are not in std. or maybe they are, but the error message is hard to understand...

Unable to build on Mac with MacPorts libgit2

I pulled exa, installed rust, cmake, and libgit2 (the last two from MacPorts). But the "cargo build" failed with the following errors:

Hello,

When file UID is > 2^31, the displayed UID wraps around and is displayed as negative. This issue probably also happens with big BIG.

exa does not compile with Rust 1.0

Hi,

if I try to compile exa with Rust 1.0, I get :

Is a migration to Rust 1.0 planned ? Having to use Rust nightly to compile exa is unwieldy.

Any chance for an OSX version

Perhaps even a brew formula?

Feature: add --group-directories-first option

GNU ls has an option called --group-directories-first which groups directories before files and then applies other sorting options. This is currently not possible unless I'm missing something.
I personally use that option on all my machines because I prefer to have directories and files listed separate from eachother.

If this feature is wanted I'll implement it and open a pull request. Unless you would prefer to do it yourself of course.

cargo build failed: could not compile gcc

I think this may not be an issue. But I did not find any other place to seek for help. So I have to report it as an issue. Sorry for the possible abuse of the issue list.

type exa | echo and you get:

Allow putting directories on top

ls has the --group-directories-first option which prints the directories first (sorted by name) and files after:

$ ls -1 --group-directories-first
src
target
Cargo.lock
Cargo.toml
LICENCE
README.md
screenshot.png

vs.

$ exa -1
Cargo.lock
Cargo.toml
LICENCE
README.md
screenshot.png
src
target

Could something like this be added to exa? It would probably have to be a separate switch (since you can only have a single sort, but putting directories first is orthogonal to e.g. sorting by an extension).

-? doesn't work with zsh

I can't speak to exactly why, as I'm not familiar with zsh internals, but -? doesn't work as you get a

$ exa -?
zsh: no matches found: -?

Yet things such as -@ seem to work just fine. This isn't a huge issue, as --help works just fine, but just FYI since I'm sure there are some other zsh users out there.

unwrap called on input/output error

Using version 0.3.0 (from AUR), calling exa on something that is no longer there (such as an external harddrive that has lost power), results in

thread '<main>' panicked at 'called `Result::unwrap()` on an `Err` value: Error { repr: Os(5) }', /home/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/libcore/result.rs:731

whereas ls gives the error

Build problem on Fedora Linux: crate name cannot start with a hyphen: -

Trying to build git head on Fedora 20 x86_64. I have installed dependencies (as mentioned at: http://bsago.me/exa/) with:

# yum install -y libgit2 libgit2-devel cmake

Running either cargo build --verbose or cargo build --no-default-features --verbosegives me:

Process didn't exit successfully: `rustc - --crate-name - --crate-type dylib --crate-type bin --print=file-names` (status=101)
--- stderr
error: crate name cannot start with a hyphen: -

It seems running make just invokes cargo build --release too. I'm not that familiar with cargo. Any pointers?

[help wanted] Use threadpool::ThreadPool instead of a blocking channel of threads

A few months ago I made pull request #45 to stat the files in parallel. Back then the ThreadPool in std was in the process of being deprecated, so I used a less efficient approach of spawning a thread for each stat task and using a sync_channel to keep track of the thread capacity. Now that ThreadPool is moved to a separate crate, I tried going back to replacing the (thread_capacity_tx, thread_capacity_rx) hack with a ThreadPool. However, I ran into some lifetime issues that I wasn't able to get around. If anyone can get it working that's be great.

Feature request: use a color scale for file sizes and dates (like k)

See this pull request to k for an example: supercrabtree/k#35

This seems to enhance usability; it's easy to spot the largest or most recent files at a glance, for example. Should also be easy to implement.

exa does not respect host timezone information

$ touch testfile
$ ls -l
total 0
-rw-r--r-- 1 jon users 0 Mar 22 17:40 testfile
$ exa -l
.rw-r--r--  0 jon 22 Mar 21:40 testfile

Since I'm currently at UTC-4, my guess is that the modification time is printed as UTC time, not local time.

GNU ls columns

You've been asking about how to calculate the columns.

First you'll have to calculate the the widths of strings which isn't easy when you have unicode file names: here

Then you'll have to get the width of the terminal: here (tested only on linux)

Then you'll have to calculate the actual widths of the columns the way GNU ls does it: here (this is very similar to the way GNU ls does it)

This code is from my own ls implementation which I'm too lazy to continue. If you want you can use it under the MIT license.

libgit2 git_status_list_new is really slow.

For me, exa takes ~3 seconds to run on the rust repository and most of this time is spent in libgit2's git_status_list_new function (specifically, it appears that most of this time is spent calculating SHA1 hashes). However, git status --porcelain runs in about .1 seconds. The correct fix would be to fix libgit2 however, in the meantime, you might consider using git directly.

Note git2::Repository::statuses(opts) is a wrapper for libgit2's git_status_list_new function.

Does Not Show Git Status in Subdirectories

If we have a modified file in a subdirectory (related to git root folder), the subdirectory is marked as modified, but the file is not. Please see the screenshot

Option to omit git status column (or disable by default)

As mentioned in #28, exa ist rather slow in larger git repositories. I know there is the possibility to use Cargo's features to compile without git support, but that is not what I want.

When using --long, the Git columns is shown automatically. I think only enabling it with a --git flag might be better.

Alternatively, I'd like to see an option to disable this column.

build fails on openssl-sys

I downloaded the latest nightly and fresh clone of exa. Also removed my .cargo folder to start fresh with new downloaded dependencies.
make install yields:

Missing '/' character in symlink target filename

I used exa to list my home directory, and noticed that some of the filenames are missing at least one / character.

Specifically, when a symlink should be printed like the following:

symlink => dirA/dirB/dirC/file

It is actually printed as:

symlink => dirAdirBdirC/file

Won't build on OSX 10.10?

I've installed the prereq's with fink plus the nightly of rust but exa does not build for me:

Could not compile `exa`.

To learn more, run the command again with --verbose.

Does not work out of the box due to regex_macros dependency issue from rust-ansi-term

See rust-ansi-term#1.
This is just for the record in case someone wants to try out exa and experiences the problem.

What is the yellow and underline for a file?

When we do exa in the directory of exa we have an output something like this:

why the files README.md and Cargo.toml are in yellow and underline?

Feature request: provide structured output

Parsing ls is an ages-old problem that exa could help solve by providing an option for producing structured key-value output. By "structured key-value output" I mean one or more of JSON (pretty much the default nowadays), YAML, XML (boo!), TOML (yay!) or Tcl dictionaries (sample).

[Packaging] Arch Linux PKGBUILD

I wrote an Arch Linux PKGBUILD for exa. Is that something you're interested in having somewhere in the source repository? I can upload it to the AUR when it's tested a bit more.

-A (--almost-all) option missing

The -A option (which doesn't list . or ..) is missing.

--time option not recognised?

ruipacheco @ traitor in ~/Projects/Assorted/exa                                                                                                                                                       
$ target/release/exa -lhart ~/Projects/xxx/yyy/
Unrecognized option: '--time /Users/ruipacheco/Projects/xxx/yyy/'.
command failed with status: 3

I'm using the fish shell, if that matters.

Color scheme for light terminals

When the background is white (or any light color), the output is hard to read.

--tree is not working

I tested it under osx and ubuntu on both system in didn't do anything (no error message or similiar).

--across does not work

$ exa --across --long
Option --across is useless given option --long.

exa doesn't seem to parse --across correctly. This is using v0.2.0 compiled with rustc 1.0.0-nightly (b4c965ee8 2015-03-02) (built 2015-03-03).

Split off grid formatting?

Hi! Exa is great. Thanks for sharing it with us.

Have you considered splitting off your grid formatting logic into a library? It seems to work really well and could be of use to other projects!
