rand-ascii: A trivial and fast random ASCII chars generator

Just a quick tool to generate <n> random ASCII chars and print them to stdout.

Build

git clone https://github.com/MoSal/rand-ascii.git
cargo build --release

Requires cargo (and rustc of course).

Check out rustup if you never built Rust code before.

Binary can be found at target/release/rand-ascii.

Usage

rand-ascii <n>

n is the number of random chars to be generated and printed. Values accept g/m/k suffices, which correspond to GiB/MiB/KiB values.

Example

rand-ascii 1g > /dev/null

Or if you want to trivially test the "performance" of some terminal emulators:

time rand-ascii 1g

Limiting printed output to ASCII (unlike let's say, cat /dev/urandom) may minimize variation of results stemming from a variation in sophistication of the text stacks utilized by each terminal.

Besides, call me paranoid, but I wouldn't feel fully confident running cat /dev/urandom in terminal emulators implemented in unsafe languages.
