Homework and Emergencies Homework & Coursework Questions Trouble with Shell Script Compressing file Post 302961420 by Don Cragun on Saturday 28th of November 2015 07:26:11 PM

You seem to be confused about how you reference parameters passed to a shell script, about how the variable name passed to and filled in by the shell's read built-n works, and about how to reference variables created in your shell script.

I would suggest re-reading the manual page for bash on your system (using the command: man bash) paying special attention to the discussion in the PARAMETERS section, in the EXPANSION section, and the description of the read utility in the SHELL BUILTIN COMMANDS section.

If you have a file named list_of_files containing:
Code:
file1
file2
file3

and the script:
Code:
#!/bin/bash
listfile="$1"
while read file
do	echo "Read filename $file from $listfile."
done < "$listfile"

in a file named readlist which you have made executable with the command:
Code:
chmod +x readlist

then see what happens when you run the command:
Code:
./readlist list_of_files

Does this help?

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to the translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the main file (which might be more up-to-date).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--outdated Merge in even outdated translations.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
