Shell Aliases & Shortcuts

Auf jeder Shell nützlich für den täglichen Gebrauch: Aliases. Wer tippt sich schon gern die Finger mit den ewig gleichen Kommandos wund ;-)
Dienstbar macht man sich die Geister, indem man sich ein File mit Aliases, Funktionen usw. anlegt und dieses dann beim Einloggen (oder von Hand) von seiner Shell einlesen lässt. (man source) Dazu eignet sich bei der Bash /etc/profile (systemweit) oder ~/.bashrc und ~/.profile. Es kann aber auch jedes andere File sein, das von irgendwoher während des Login-Prozesses gesourced wird.
Hier ein paar Anregungen:

Und noch ein paar Beispiele aus /etc/profile

# set up the color-ls environment variables:
if [ "$SHELL" = "/bin/zsh" ]; then
eval `dircolors -z` ;
elif [ "$SHELL" = "/bin/ash" ]; then
eval `dircolors -s` ;
else
eval `dircolors -b /etc/DIR_COLORS` ;
fi

# check for new files

# Notify user of incoming mail. This can be overridden in the user's
# local startup file (~/.bash.login or whatever, depending on the shell)
