(I might complan a little less if git-repack would take -adlf rather than insisting on -a -d -l -f. Is that a deliberate choice or has just nobody stepped up to revamp the option parsing?)
getopt is our friend, indeed. (http://www.hmug.org/man/1/getopt.php) The following code fragment shows how one might process the arguments for a command that can take the options -a and -b, and the option -o, which requires an argument. args=`getopt abo: $*` # you should not use `getopt abo: "$@"` since that would parse # the arguments differently from what the set command below does. if [ $? != 0 ] then echo 'Usage: ...' exit 2 fi set -- $args # You cannot use the set command with a backquoted getopt directly, # since the exit code from getopt would be shadowed by those of set, # which is zero by definition. for i do case "$i" in -a|-b) echo flag $i set; sflags="${i#-}$sflags"; shift;; -o) echo oarg is "'"$2"'"; oarg="$2"; shift; shift;; --) shift; break;; esac done echo single-char flags: "'"$sflags"'" echo oarg is "'"$oarg"'" This code will accept any of the following as equivalent: cmd -aoarg file file cmd -a -o arg file file cmd -oarg -a file file cmd -a -oarg -- file file - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
