Aliases in Terminal

Es ist ebenso möglich die Ausführung des Skriptes oder Teile davon in eigene Befehle zu verpacken - Stichwort "Alias"

Alle Befehle erfordern ggfs. das Computer-Passwort.

Der Befehl wwu-vpn-check produziert keine Ausgabe, wenn der VPN nicht aktiv ist und gibt die ID des Prozesses wieder, wenn der VPN aktiv ist.

Für zsh

Datei ~/.zshrc anpassen:

alias wwu-vpn-connect="sh ~/Documents/scripts/wwu-vpn.sh" // Je nachdem wo das Skript liegt
alias wwu-vpn-disconnect="sudo killall openconnect" 
alias wwu-vpn-check="sudo pgrep openconnect"

Für fish

Datei in ~/.config/fish/config.fish

alias wwu-vpn-connect "sh ~/Documents/scripts/wwu-vpn.sh" // Je nachdem wo das Skript liegt
alias wwu-vpn-disconnect "sudo killall openconnect"
alias wwu-vpn-check "sudo pgrep openconnect"
