chas (char + has)
chas is a lightweight CLI utility that reads lines from standard input and filters
them based on whether they contain a specific set of characters.
Installation
go install github.com/Nadim147c/chas@latest
Usage
Pass the characters you are looking for as arguments, and pipe your text into chas.
# Basic usage
chas abc < file.txt
# Using multiple arguments (joined automatically)
echo "hello world" | chas hlo
How it works
chas performs an AND operation on the provided characters. A line will only be
printed to stdout if all the characters specified are present somewhere within
that line.
