lilgrep

A miniature version of the grep command line tool built with Rust.

Search for a specific word within a file, and the entire line(s) containing that word will be returned to you.

• Basic usage

• Case sensitivity

• Directing the output to a file

Requirements:

• Must have Rust installed on your OS

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Basic usage

• Search for the word what within the file poem.txt:

cargo run what poem.txt

Case sensitivity

By default, the search is case sensitive.

If "What" exists but not the search query "what", nothing will be returned.

This is dependant upon this environment variable:

CASE_INSENSITIVE=

• To change this, all you need to do is run:

export CASE_INSENSITIVE=true

• To remove:

unset CASE_INSENSITIVE

Directing the output to a file

• Search for every case of "what" within poem.txt, and direct the result to output.txt

cargo run what poem.txt > output.txt
