regex-cli-test

A simple command line utility for writing regex checks. Currently only matches a full string against a pattern. Non-matching strings will return an exit code of 1. Matching strings will return 0.

Installation

Simply use cargo to install from crates.io.

$ cargo install regex-cli-test

Example: Matching from standard input

$ if echo -n "a" | regex '\w'
> then
> echo "Matches!"
> fi
Matches!

Example: Standard input pattern

$ echo -n "\w+" | regex - hello && echo "Matches!"
Matches!
