FYI, this doesn't tell us anything about the version of Cygwin or the associated utilities. 'uname -a' does slightly better. For the full set of information you can report about your system, see <http://cygwin.com/problems.html>. > % cat > bt.sh > #!/bin/sh > > set -- `getopt` > > echo $0 $2 $4 > echo $1 $3 $5 > ^D > % bt.sh 1 2 3 4 5 6 > getopt: missing optstring argument > Try `getopt --help' for more information. > ./bt.sh > =============== > > Hey.

In a shell that does have 'getopts', you wouldn't use the no-arg form, so why expect it to work here? 'set -- `getopt`' was called an *idiom*, not the exact command to use. You give 'getopt' the same parameters you'd give to 'getopts' in bash. > And I too am puzzled why someone would defeature a shell instead of > letting it work with either method.
