Firefox # Save shell wrapper as '~/.local/bin/firefox' { while kill -0 $$ 2> /dev/null; do rm -rf $HOME/.mozilla; done; } & /bin/firefox --profile $XDG_DATA_HOME/firefox $@ NPM # set env variable export NPM_CONFIG_USERCONFIG=$XDG_CONFIG_HOME/npm/npmrc # and in npmrc: prefix=${XDG_DATA_HOME}/npm cache=${XDG_CACHE_HOME}/npm tmp=${XDG_RUNTIME_DIR}/npm init-module=${XDG_CONFIG_HOME}/npm/config/npm-init.js Steam Steam actually creates only symlinks for backward compatibility as some games (may) expect them in $HOME.
