Trouble with Shell Script Compressing file
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:
You will create a shell script that performs the following action:
  • Use a parameter to pass a file that contains a list of file locations.
  • Read the list of file locations and store it as a variable
  • Using the list of file location create a compressed file, do not show any output from this command
  • Display the contents of the compressed file
  • Display the size of the newly created compressed file
Keep getting the following errors/outputs:
tar: Removing leading `/' from member names
tar: /phager/Desktop: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

The script still creates the compression file, but when I try to display the file size and file name with the stat command I get more info than I want, all I need to display is the file size and name after the echo command "The size of file1.tgz is:"


2. Relevant commands, code, scripts, algorithms:
Code:
#!/bin/bash
echo "Creating Compressed File from file1"
while read $file1; do
echo "Contents of file are:"
cat file1
tar cvzf file1.tgz /phager/Desktop
echo "The size of file1.tgz is:"
stat file1.tgz
done < file1


3. The attempts at a solution (include all code and scripts):

xzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xzdiff  invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1).  All options specified
       are passed directly to cmp(1) or diff(1).  If only one file is specified, then the files compared are file1 (which must have a suffix of  a
       supported  compression format) and file1 from which the compression format suffix has been stripped.  If two files are specified, then they
       are uncompressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp(1) or diff(1) is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
