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

pull-lp-source

PULL-LP-SOURCE(1)					      General Commands Manual						 PULL-LP-SOURCE(1)

NAME

       pull-lp-source - download a source package from Launchpad

SYNOPSIS

       pull-lp-source [options] source package [release|version]

DESCRIPTION

       pull-lp-source  downloads  and  extracts  the  specified version of <source package> from Launchpad, or the latest version of the specified
       release.  To request a version from a particular pocket say release-pocket (with a magic -release for only the release pocket).	If no ver-
       sion or release is specified, the latest version in the development release will be downloaded.

OPTIONS

       Listed below are the command line options for pull-lp-source:

       source package
	      This is the source package that you would like to be downloaded from Launchpad.

       version
	      This is the version of the source package to be downloaded.

       release
	      This  is	the  release that you would like the source package to be downloaded from.  This value defaults to the current development
	      release.

       -h, --help
	      Display a help message and exit.

       -d, --download-only
	      Do not extract the source package.

       -m UBUNTU_MIRROR, --mirror=UBUNTU_MIRROR
	      Use the specified Ubuntu mirror.	Should be in the form http://archive.ubuntu.com/ubuntu.  If the package isn't found on	this  mir-
	      ror, pull-lp-source will fall back to Launchpad, as its name implies.

       --no-conf
	      Do not read any configuration files, or configuration from environment variables.

ENVIRONMENT

       All  of	the  CONFIGURATION  VARIABLES  below are also supported as environment variables.  Variables in the environment take precedence to
       those in configuration files.

       DIST   Specifies the default target.

CONFIGURATION VARIABLES

       The following variables can be set in the environment or in ubuntu-dev-tools(5) configuration files.  In  each  case,  the  script-specific
       variable takes precedence over the package-wide variable.

       PULL_LP_SOURCE_UBUNTU_MIRROR, UBUNTUTOOLS_UBUNTU_MIRROR
	      The default value for --mirror.
