I have written a simple tool called mann (https://github.com/soheilpro/mann) to help me remember little things that I learn when working in Bash/Zsh.

Basically, every time I learn something useful about a command, I add it to its mann page and then whenever I need it in the future, I simply run 'mann <command>' to find it.

Here's the current output of my 'mann sed', for example:

  # Add char to beginning of each line
  sed 's/^/#/'

  # Replace with newline
  sed 's/<oldvalue>/\'$'\n''/g'

  # Replace newline
  sed -e ':a' -e 'N' -e '$!ba' -e 's/\n/<newvalue>/g'

  # Plus sign
  sed -E 's/foo+/bar'

  # Digit
  sed -E 's/[[:digit:]]/bar'

  # Inplace
  sed -i'.bak' -e <pattern> <file>

This looks great. I've always kept those types of little snippets in the README of my dotfiles repo - and always keep a printed out copy on my desk. But this seems way more practical.
