This sounds like homework. We have a special forum for that.

However:
Code:
#!/bin/ksh
# parms $1 = absolute path to files
path="$1"
cd $path
ls |
while read fname
do
   if [ -f $fname  ] ; then # is this a regular file, not a dir or pipe, etc
      ls -l $fname 
   fi
done | sort -n -k 5

watch spaces arounnd brackets....

Code:
( find $path -type f | xargs -n101 ls -l ) | sort -n -k 5
