Drush cache clear

gistfile1.sh

# Clear specific drupal cache table with drush
# $1 - Cache table or "theme" for css-js.
# $2 - Environment drush alias. Ex: @mysite.dev
_drcc() {
  # alias "css-js" to "theme" because I can never remember which comes first.
  if [ "$1" == "theme" ] ; then
    table="css-js"
  else
    table=$1
  fi

  if [ -z "$2" ]; then
    # Redirect the output to /dev/null so we can do a custom message.
    drush cc "$table" &> /dev/null 
    echo "Cleared $table cache on the current environment."
  else
    # Redirect the output to /dev/null so we can do a custom message.
    drush "$2" cc "$table" &> /dev/null
    echo "Cleared $table cache on $2." 
  fi
}

alias drcc="_drcc"

Examples

Clear menu cache on @mysite.dev:

drcc menu @mysite.dev

Clear css-js cache on the current local environment:

drcc css-js

or...

drcc theme

This works because "theme" has been aliased to "css-js" since I can never remember if it's "css-js" or "js-css"
