You can probably achieve the required fied separation by setting IFS=-
and getting the shell to split the string.
Maybe something like (untested):
save_ifs="$IFS"
IFS=-
set -- x-$version
shift # remove the 'x' added in case $version empty
IFS="$save_ifs"
# I think the script now wants the last two subfield removed,
# an inital "mutt-" removed and the '-' replaced with '.'
[ "$1" = mutt ] && shift
ver="$1"
while [ $# -gt 2 ]; do
[ "$1" != rel ] && ver="$ver.$1"
shift
done
distance="$1"
commit="$2"
Removing the last two fields is the tricky part!
The '-' could be replaced with '.' by just doing:
IFS=-
set -- $version
IFS=.
version="$*"
