Iterate through command line parameters and append to string

Question

I have ./basscript parm1 parm2 parm3

I want to iterate through the parms starting from parm2 till parmN and append them to a variable.

How do I get ${COMPLETE}="parm1,parm2,parmN"?

Answer 1

Maybe something like this:

COMPLETE=""
shift
for a in "$@"
do
        if [ "$COMPLETE" == "" ]; then COMPLETE="$a"; else COMPLETE="$COMPLETE,$a" ; fi
done
echo $COMPLETE

This makes COMPLETE a comma-separated list of all the parameters, excluding the first.

Answer 2

IFS=","
echo  "${*:2}"
