bash - Cross-platform getopt for a shell script -

i've found out getopt not cross-platform (in particular freebsd , linux). best workaround issue?

use getopts (with "s").

according bash faq 35:

unless it's version util-linux, , use advanced mode, never use getopt(1). getopt cannot handle empty arguments strings, or arguments embedded whitespace. please forget ever existed.

the posix shell (and others) offer getopts safe use instead.
