Homework and Emergencies Homework & Coursework Questions Command combination for displaying header and content Post 302914569 by Don Cragun on Tuesday 26th of August 2014 04:59:42 PM

I agree with everything bakunin said.

In addition, I'll add a few more comments:
  1. I don't understand why you are so interested in printing lines 1 and 3. I don't see anything in the objectives stated in the homework template saying anything about any line number (although it might be appropriate to assume that the header is one line and that that line is the 1st line in the file).
  2. For the stated problem, awk, grep, and sed seem like logical choices to me.
  3. If you want to print lines selected by line numbers, awk and sed would still seem to be logical choices.

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
