Homework and Emergencies Homework & Coursework Questions 2. Write a shell script that produces some summary information of the system at a particular moment Post 302522462 by agama on Sunday 15th of May 2011 12:19:32 PM

Given that this is for an assignment, I'll only make a few suggestions that should allow you to figure it out.

First, check out the man page for the who command. This should help with your first requirement.

Secondly, ps -e probably isn't going to give you enough information based on your requirements. Again check the man page, particularly the -o option. This will be key in meeting the second requirement of having your sort field be the first column.

Yes, piping the output of the ps command through the sort and head commands will indeed give you the desired output for the last part of your assignment, so you are on the right track. Right now you need to tailor the ps command to generate the needed data in the output.

Man pages are nicely linked from the unix.com site (see the top menu bar) for a fair few number of UNIX flavours. This should make getting a handle on these commands easier.

Hope this helps to get you going again.

NAME
mkcover - HylaFAX continuation cover page generation command SYNOPSIS
/var/spool/hylafax/bin/mkcover qfile template result DESCRIPTION
bin/mkcover is the command invoked by the facsimile server when a continuation cover page is required for an outbound job that is about to be retried. It generates a single POSTSCRIPT(R) page that is imaged according to the remote capabilities and transmitted as the cover page. The arguments are: qfile the job description file for the outbound job. template the cover page template file, as used by the faxcover(1) program. result the filename where the resultant POSTSCRIPT document should be written. The default mkcover command is a shell script that uses awk(1) to parse the job description file and generate the cover page document. The template file may be optionally compressed with compress(1), pack(1), or gzip(1); the filename suffix is used to decide whether or not the template file contains compressed data. SEE ALSO
