I wish to have long and short forms of command line options invoked using my shell script. I know that getopts can be used, but like in Perl, I have not been able to do the same with shell. Any ideas on how this can be done, so that i can use options like: ./shell.sh --copyfile abc.pl /tmp/ ./shell.sh -c abc.pl /tmp/ In the above, both the commands mean the same thing to my shell, but using, getopts, I have not been able to implement these? shell unix getopt getopts link|improve this question edited Oct 4 '11 at 9:39 Jawa 826516 asked Dec 31 '08 at 5:49 gagneet 1,73662346 99% accept rate

The bash getopts builtin does not support long option names with the double-dash prefix. It only supports single-character options. There is a shell tool getopt which is another program, not a bash builtin. The GNU implementation ofgetopt (e.g. on Linux) supports parsing long options. But the BSD implementation of getopt (e.g. on Mac OS X) does not. link|improve this answer answered Dec 31 '08 at 6:27 Bill Karwin 107k16121264
