grepenv 1.1.1

grep's the env

grepenv 🔎

greps your env

About

A little tool to search through your environment.

I made grepenv to simplify the process of calling various combinations of env | grep | sort, and replicating my aliases for this across machines.

Installation

grepenv can be installed using pip, but pipx is recommended:

pipx install grepenv

This installs the grepenv shell script:

grepenv --help 
ge --help # The short alias 'ge' is also available

Usage

grepenv takes a regex pattern, and matches it against currently available environment variables. Calling grepenv --example will show some example usage.

$ grepenv xdg # Will find any key or value that contains the letters xdg (lower or upper case).

$ grepenv "_api_(key|token)_" --keys # finds any environment variable with this regex pattern, matching only on keys.
GITHUB_API_TOKEN=abc_NlNhalNDL78NAhdKhNAk78bdf7f
OPENAI_API_KEY=123_abcdefghijklmno

$ grepenv --find-key gitlab # Search for an environment variable with the name gitlab, and output it's value.
123_abcdefghijklmnop
# GITLAB_API_TOKEN=123_abcdefghijklmnop

$ grepenv perl --path # Search for the pattern "perl", but only in the PATH
/usr/bin/site_perl
/usr/bin/vendor_perl
/usr/bin/core_perl
