Removing spaces from output

Hey All,

I've got a unix script that is checking whether the current date is more than 2 days difference to the date in a database. I know exactly what the issue is, but I can't figure a solution. Firstly, here's the script:

sqlplus -s generalapps/******@auam33pd >escalateoutput.sh <<SQL_END
set head off
set feedback off
set pages 0
set lines 500

     'if (( ' || (sysdate - wl.opp_date) || ' > 2 )) ; then' || chr(13) || chr(10) ||
        'mailx -s ' || chr(39) || 'Win/Loss Report' || chr(39) ||
        ' drewwalkeris@alwaysonline.net.au <<MSGEND' || chr(13) || chr(10) ||
        'Test ' ||
        chr(13) || chr(10) || 'MSGEND' || chr(13) || chr(10) ||
     mde_user.opportunity opp, mde_user.ad_user adusr, mde_user.employee emp, generalapps.win_loss wl
        (opp.dek_opportunity = wl.dek_opportunity AND wl.report_status = 'Initiated')
        AND (opp.dek_ad_user = adusr.dek_ad_user
        AND adusr.dek_employee = emp.dek_employee);


chmod 777 escalateoutput.sh
ksh escalateoutput.sh

Here's a sample of what the output is like:

if (( .740497685185185185185185185185185185185 > 2 )) ; then                    
mailx -s 'Win/Loss Report' WalkeD2@AUSTRALIA.Stortek.com <<MSGEND              

The problem is that the output is actually this (The *'s indicate spaces):

if (( .740497685185185185185185185185185185185 > 2 )) ; then********************
mailx -s 'Win/Loss Report' WalkeD2@AUSTRALIA.Stortek.com <<MSGEND***************

If I remove the spaces from the outputfile and then execute it, it works fine. If I leave the spaces, I get "'fi' unexpected". Is there a way to get around this?

I've been testing with copying and pasting the code directly into korn shell, and it seems the only way to get around it is by getting rid of those spaces some how.

Many Thanks,

Hey, sorry guys, I realised I made a stupid mistake, I can just include "sysdate - wl.opp_date > 2" into the WHERE clause and remove the "if" statement. This question can be deleted or left so that people don't make the same stupid mistake. :)

Well, I'm already here, so I thought I'd pass along a solution, in case you need something like this again.  You can use sed to strip out occurrences of more than one blank space, as in:

sed -e "s/  *//g" < testfile.sh > strippedfile.sh

Note that there are TWO blank spaces before the asterisk in this commnand.  We are finding two more more blank spaces in file testfile.sh and replacing them with nothing, then outputting it to a new file called strippedfile.sh.
