List by size

I am trying to create a script to list files by size. I was able to show a long listing before adding parameters (first comment) but nothing seems to work after trying to add them. If the first or only parameter is -r the output should be descending order by size, if the parameter is anything else like "*.c" it should list all C programs before passing the output to the grep and sort.

The script says if found "-r" when it isn't there and vice versa and entering a star name parameter expands to the first occurrence of the specified item.

All ideas appreciated. TIA

Code:

rev=""
if [ $# -gt 0 ]
  then
  if [ $1 -eq "-r" ]
  then
    rev="-r"
    echo found -r
    shift
  fi
fi
#ls -l |grep -v "total " |sort +4n -5 +8
#ls -l $1 |grep -v "total " |sort $rev +4n -5 +8 |more -e
echo ls -l $1 grep -v "total " sort $rev +4n -5 +8 more -e

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
