like `test` but verbose

Semi-lightweight test and grep wrappers

Wrappers for test and grep which will output the args when they fail.

The wrappers use bash (sorry sh is not supported due to quote escapping for {$var@Q}.

acbtest

Wraps the test command, and outputs the command to stderr if it fails, e.g.

$ ./acbtest "abc" = "acb"
test 'abc' '=' 'acb' failed

acbdiff

Wraps the diff command, and outputs the command to stderr if it fails, e.g.

$ ./acbdiff <(echo hello) <(echo Hello)
1c1
< hello
---
> Hello
diff '/dev/fd/63' '/dev/fd/62' failed

acbgrep

Wraps the grep command, and outputs the command to stderr if it fails; additionally if reading from a pipe, it will also display the contents of the pipe.

$ ./acbgrep o some-file 
hello
world

$ cat some-file | ./acbgrep o
hello
world

$ ./acbgrep bye some-file 
grep 'bye' 'some-file' failed

# special case where stdin is printed on failure
$ cat some-file | ./acbgrep bye
hello
world
grep 'bye' failed

# disable echoing stdin with
$ cat some-file | ACBGREP_NO_ECHO=1 ./acbgrep bye
grep 'bye' failed
