/***** unido:mod.std.unix / ut-sally!jsq / 8:54 pm Jul 4, 1985*/ From: John Quarterman (moderator) <ut-sally!std-unix> Topic: yet more on getopt (command line arguments) Two more messages, the first a followup to a previous posting, and the second public domain sources and man pages for getopt(3) and getopt(1). -mod ---------------------------------------------------------------------- From: ihnp4!utzoo!henry Date: 3 Jul 85 18:34:41 CDT (Wed) To: ihnp4!ut-sally!std-unix Subject: Re: command line arguments > > A group of bundled options may end with an option that has an argument. > > This creates confusion in using C-Kermit when you want to send an image > file. For example: > > send -is filename < --- works fine > send -si filename < --- bombs the program The AT&T syntax standard (which getopt does not completely enforce) actually forbids both of these usages. Options with arguments are not allowed to be bundled, and they must be separated from their arguments by a space. > I would *much* prefer to bundle the flags, then > have those with arguments pick them up in the same order as the flags are > listed. The few existing commands that use such a convention, notably tar(1), are (in my experience) the worse for it. It's seriously error-prone. I think the AT&T people did the right thing. ------------------------------ Date: Tue, 2 Jul 85 13:07:09 edt From: ihnp4!utcs!ian (Ian F. Darwin) To: ihnp4!ut-sally!jsq@tzec.UTEXAS.ARPA Subject: here is getopt Here is the source for getopt(3), the function that should be in everybody's C program, and getopt(1), a program that uses it to make shell programs comprehensible and consistent. There are man pages for both. Please send these on to the mod. group. Thanks. [ I have hacked the following shell script slightly so that it doesn't extract directly into system source directories, rather into the current directory. It should be assumed that this code comes with no warranty from me, Ian Darwin, or anyone else as to whether it accurately represents getopt as distributed with System V, or any command line standard, or that it works at all, or that it will cause no damage when extracted or used. -mod]
