Examples

To create a shortcut called sco for savcom:

$ savcom do sco savcom '"$@"'
sco: command shotcut created.

The '"$@"' is mandatory here, since we want be able to pass options to savcom.
Also notice the surrounding single quotes. They are needed to prevent the shell from interpreting "$@".

It is good practice to quote commands, like so:

$ savcom do ma 'if [ -f ./manage.py ]; then ./manage.py "$@"; else echo "Not a Django project directory!"; fi'
ma: command shortcut created.

Otherwise it gets a little tricky :

$ savcom do ma if \[ -f ./manage.py \]\; then ./manage.py '"$@"'\; else echo '"Not a Django project directory!"'\; fi
ma: command shortcut created.

This shortcut launches Django's command-line utility manage.py if it can be found in the current directory.

Now, to invoke a shortcut, simply type it on the command line, i.e:

$ sco version
savcom version 0.2.1.

Save command shortcuts into a file:

savcom dp shortcuts.txt

Remove all shortcuts:

while read -r; do echo "rm $REPLY" | cut -d '=' -f 1 | savcom; done < <(savcom ls)

Restore shortcuts from a file:

savcom < shortcuts.txt
