Compare text strings.
Hi Im trying to write a script that compare a text string.
But it fails, I think it adds a extra line feed to the result and fails beacuse of that.

The script.

Code:
DT=`date +'%Y%m%d%H%M%S'`
#ALARM_BIN=/users/alarms/ssa/alarms/bin
QUEUE_THR=10
#unset offset
#offset="***Server reports data not found"
#offset=330000
offset=`xntpdc -p |awk '{ print $7 }' |tail -1| (sed -e 's/^-//' -e 's/\.//')`
echo "$offset"
if [ "$offset" = "***Server reports data not found" ]; then
        echo "Connection to NTP server lost"
        ${ALARM_BIN}/alarm_raise NTPCHECK ntp_check 8 8505 MAJOR "Connection to NTP server lost" SSOO

        else
        if (( $offset > 300000 )); then
        echo "Client clock off by 0.3 seconds or more"
        ${ALARM_BIN}/alarm_raise NTPCHECK ntp_check 8 8507 MAJOR "Client clock off by 0.3 seconds or more" SSOO

        else
        echo "NTP server connection and client clock OK"
        ${ALARM_BIN}/alarm_raise NTPCHECK ntp_check 14 8606 CLEAR "NTP server connection and client clock OK" SSOO
        fi
fi

The result is as follows
If the ntp server is available it returns a number
Code:
ntp_check
0060277
NTP server connection and client clock OK

If the ntp server is unavailable
ntp_check
***Server reports data not found

./ntp_check[16]:   > 300000 : syntax error

It fails doing the comparision I dont understand why.
Why is there a blank line below
Code:
***Server reports data not found

Thanks.

osacompile

OSACOMPILE(1)						    BSD General Commands Manual 					     OSACOMPILE(1)

NAME

     osacompile -- compile AppleScripts and other OSA language scripts

SYNOPSIS

     osacompile [-l language] [-e command] [-o name] [-d] [-r type:id] [-t type] [-c creator] [-x] [-s] [-u] [-a arch] [file ...]

DESCRIPTION

     osacompile compiles the given files, or standard input if none are listed, into a single output script.  Files may be plain text or other
     compiled scripts.	The options are as follows:

     -l language
	   Override the language for any plain text files.  Normally, plain text files are compiled as AppleScript.

     -e command
	   Enter one line of a script.	Script commands given via -e are prepended to the normal source, if any.  Multiple -e options may be given
	   to build up a multi-line script.  Because most scripts use characters that are special to many shell programs (e.g., AppleScript uses
	   single and double quote marks, ``('', ``)'', and ``*''), the command will have to be correctly quoted and escaped to get it past the
	   shell intact.

     -o name
	   Place the output in the file name.  If -o is not specified, the resulting script is placed in the file ``a.scpt''.  The value of -o
	   partly determines the output file format; see below.

     -x    Save the resulting script as execute-only.

     The following options are only relevant when creating a new bundled applet or droplet:

     -s    Stay-open applet.

     -u    Use startup screen.

     -a arch
	   Create the applet or droplet for the specified target architecture arch.  The allowable values are ``ppc'', ``i386'', and ``x86_64''.
	   The default is to create a universal binary.

     The following options control the packaging of the output file.  You should only need them for compatibility with classic Mac OS or for cus-
     tom file formats.

     -d    Place the resulting script in the data fork of the output file.  This is the default.

     -r type:id
	   Place the resulting script in the resource fork of the output file, in the specified resource.

     -t type
	   Set the output file type to type, where type is a four-character code.  If this option is not specified, the creator code will not be
	   set.

     -c creator
	   Set the output file creator to creator, where creator is a four-character code.  If this option is not specified, the creator code will
	   not be set.

     If no options are specified, osacompile produces a Mac OS X format script file: data fork only, with no type or creator code.

     If the -o option is specified and the file does not already exist, osacompile uses the filename extension to determine what type of file to
     create.  If the filename ends with ``.app'', it creates a bundled applet or droplet.  If the filename ends with ``.scptd'', it creates a bun-
     dled compiled script.  Otherwise, it creates a flat file with the script data placed according to the values of the -d and -r options.

EXAMPLES

     To produce a script compatible with classic Mac OS:

	   osacompile -r scpt:128 -t osas -c ToyS example.applescript
