Mhmm, doesn't that break things, as $# will always be 1 if you do
set -- "$some_variable"
no matter how many instances of $IFS there are in $some_variable:
$ foo="/a/b/c/d"
$ IFS='/'
$ set -- "$foo"
$ echo $#
1
$ echo "$1"
a/b/c/d
Actually, $# should be 4 and $1 should be "a"
I'd rather suggest using
set -f
set -- $some_variable
set +f
to disable wildcard expansion for the set-statement:
$ foo="/var/tmp/*"
$ IFS='/'
$ set -f
$ set $foo
$ set +f
$ echo $#
3
$ echo "1: $2, 2: $2, 3: $3"
1: tmp, 2: tmp, 3: *
Ciao
