POSIX says you must break it into: [ ... ] || [ ... ] or, more efficiently for this particular filtering, rewrite this as: # munge reserved words case $arg in limit | in | next ) arg=_$arg ;; esac > > Could we add 'self' to this list? and using case makes it easier to add more reserved words: case $arg in limit | in | next | self ) arg=_$arg ;; esac

In this case it would be neater to use 'case' anyway: case "$arg" in limit|in|next) arg="_$arg" ;; esac -- PMM
