[bash] rgb to hex

readme.md

hex.sh

This is a tiny bash function to convert rgb (0-255,0-255,0-255) into hexadecimal (000000-FFFFFF).

hex() { bash -c """printf "%02X%02X%02X" $(echo $* | tr , \ )"""; }

Usage

It can interpret a few different input styles:

hex 255 255 255   # FFFFFF
hex 255,255,255   # FF0000
hex "128 200 250" # 80C8FA

Install

Just drop the function in your ~/.bash_aliases (or .zshrc.local if you are using ZSH) and restart your terminal.

I've tested all this on macOS (darwin) and Debian/Ubuntu, without any issues.
This also works on iOS via iSH (Alpine Linux). Windows... not so much.
