Compare output from two commands
Hello folks,
I would like ask for a help in one script I'm currently working on.
Main goal is to compare size of file available on remote site and file already downloaded (check if downloaded file is complete and non corrupted).

Code:
# Check if files were downloaded correctly
for FILES in $FILES_TO_DOWN
   do
        LOCAL_SIZE=`ls -la $FILES | awk '{print $5}'`
        REMOTE_SIZE=`$CURL -sI -u user:pass --proxy http://gw:8080 --proxy-user user:pass https://remote_site/$FILES | grep 'Content-Length:' | cut -f 2
 -d" " | tr -d ' '`
        if [ "$LOCAL_SIZE" -eq "$REMOTE_SIZE" ]
                then
                        echo "File is OK"
                else
                        echo "File is corrupted"
        fi
done

In output from script I see this:
Code:
+ for FILES in '$FILES_TO_DOWN'
++ ls -la file_20130715.xls
++ awk '{print $5}'
+ LOCAL_SIZE=89984
++ /opt/sfw/bin/curl -sI -u user:pass --proxy http://gw:8080 --proxy-user user:pass https://remote_site/$FILES/file_20130715.xls
++ grep Content-Length:
++ cut -f 2 '-d '
++ tr -d ' '
+ REMOTE_SIZE=$'89984\r'
+ '[' 89984 -eq $'89984\r' ']'
: integer expression expectedine 53: [: 89984
+ echo 'File is corrupted'
File is corrupted

So it looks that local file size is returned as integer and size of remote file is returned as a string.
Can anybody kick me to the right way how do get rid of it?? I suppose that reasonable is try to get size of remote file as well as integer.

Many thanks,
Stan
