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

CONNECT-PROXY(1)					      General Commands Manual						  CONNECT-PROXY(1)

NAME
connect-proxy -- connect over SOCKS4/5 proxy SYNOPSIS
connect-proxy [-dnhst45] [-R resolve ] [-p local-port ] [-w secs ] [-H [user@]proxy-server[:port]] ] [-S [user@]socks-server[:port]] ] [-T proxy-server[:port] ] [-c telnet-proxy-command ] [host] [port] DESCRIPTION
connect-proxy open connection over SOCKS4/5 proxies Please, note that any HTTP-Proxy tunnel won't work with content-inspection firewall (unless using SSL). OPTIONS
-H specifies a hostname and port number of the http proxy server to relay. If port is omitted, 80 is used. You can specify this value in the environment variable HTTP_PROXY and pass the -h option to use it. -S specifies the hostname and port number of the SOCKS server to relay. Like -H, port number can be omitted and the default is 1080. You can also specify this value pair in the environment variable SOCKS5_SERVER and give the -s option to use it. -4 specifies SOCKS relaying and indicates protocol version to use. It is valid only when used with '-s' or '-S'. Default is '-5' (protocol version 5) -R method to resolve the hostname. Three keywords ("local", "remote", "both") or dot-notation IP address are acceptable. The key- word "both" means, "Try local first, then remote". If a dot-notation IP address is specified, use this host as nameserver. The default is "remote" for SOCKS5 or "local" for others. On SOCKS4 protocol, remote resolving method ("remote" and "both") requires protocol 4a supported server. -p will forward a local TCP port instead of using the standard input and output. -P same to '-p' except keep remote session. The program repeats waiting the port with holding remote session without disconnecting. To connect the remote session, send EOF to stdin or kill the program. -w timeout in seconds for making connection with TARGET host. -d used for debug. If you fail to connect, use this and check request to and response from server. USAGE
To use proxy, this example is for SOCKS5 connection to connect to "host" at port 25 via SOCKS5 server on "firewall" host. connect-proxy -S firewall host 25 SOCKS5_SERVER=firewall; export SOCKS5_SERVER; connect-proxy -s host 25 For a HTTP-PROXY connection: connect-proxy -H proxy-server:8080 host 25 HTTP_PROXY=proxy-server:8080; export HTTP_PROXY; connect-proxy -h host 25 To forward a local port, for example to use ssh: connect-proxy -p 5550 -H proxy-server:8080 host 22 ssh -l user To use it along ssh transparently: # file://~/.ssh/config # not using proxy on lan Host 192.* ProxyCommand connect-proxy %h %p # mandatory to access the internet Host * ProxyCommand connect-proxy -H proxyserver:8080 %h %p Or for all users ( /etc/ssh/ssh_config ) ENVIRONMENT
