A Bash script that lists all unused css classes in html/haml/erb files for rails project (or maybe others depending on project structure)
#!/bin/bash
cat $(find app/assets/stylesheets/ -type f) |
grep -Eo '\.[a-z]+[a-z0-9_-]*' | sort | uniq | sed s/.// |
while read CSS; do
if ! grep -Erqi "([^(remove|has)]?class[(:|=|[:space:]*=>[:space:]*)]*[[:space:]\W]*[(\"|')]*[-a-z0-9[:space:]]*$CSS|\\.$CSS\b)" app/views/ vendor/assets/ app/assets/javascripts/; then
echo $CSS >> unused.scss;
fi
done

Allow root logon

  1. Swap to console mode (ctrl+alt+F3)
  2. Login as root
  3. In /usr/share/config/kdm/kdmrc, change AllowRootlogon = false to true

Simplest list hidden files only

ls -ld .* OR ls -ld .??*

mkv to mp4

Rspec behaviour
Ruby will interprete variable inside "it block" before calling let.
So don't use the same varible name as let in the block.
