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?
