List should have an optional (IF any at all) argument, saying, if one provides the servername or ip, it lists just that one, otherwise (empty,missing) it lists all.
So assume to 'remove' the argument requirement, but check if anything else were supplied..
Changes:
Code:
eval set -- $(getopt -l edit:,list,mount:,unmount:,help,debug -o e:l:m:u:hd -- "$@")
And then check within the 'list' function like [ -z $server_info ] && echo 'list all' || echo 'list only $server_info'
And thanks to the local example and Chubler's adaption of my code, i finaly understood that shift thing.
