Homework and Emergencies Homework & Coursework Questions Understanding Getopts in an otherwise easy assignment Post 302892919 by Don Cragun on Saturday 15th of March 2014 08:48:04 PM

Have you written a man page for your shell script?
What does the SYNOPSIS section of your man page look like?
How are the -a, -f, and -z options supposed to affect the behavior of your script?

I could guess that the -f option for your script is supposed to take a filename option-argument specifying a file containing a list of user names (which means that your getopts option list should have a : after the f; or that -f means that the operand(s) to your shell script are filenames of files containing user names rather than having user names as operands.

Have you tried looking at the POSIX man page for getopts available on this site: getopts(1P)? Do you have questions about how the example in that man page works?

NAME
debconf-mergetemplate - merge together multiple debconf template files SYNOPSIS
debconf-mergetemplate [options] [templates.ll ...] templates DESCRIPTION
Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program. This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified files will be read in, merged, and output to standard output. This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the english versions of the fields they translated, for their reference. So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the main file (which might be more up-to-date). This program handles that case properly, just list each of the translated templates files, and then your main templates file last. OPTIONS
--outdated Merge in even outdated translations. The default is to drop them with a warning message. --drop-old-templates If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire template. SEE ALSO
