               if ($um_ext=="1.txt") then set um_ext_new=1
               else

         set umr_nm= "$umr_bh $um_ext_new b .txt"
         mv $file_nm  $umr_nm
      }
      endif
end

why i always got the error:

if: Expression syntax error?

Thanks so lot.

I'm no expert, but doesn't an 'if' statement usually end with 'fi'?

add an -x to the shebang, you'll easily see what's wrong.
in fact, you need an extra space in

if ($bh_nm != $umr) then

there.....................^

then you'll have another mistake as csh doesn't seem to know about '{' or '}'

Guys,

I have an issue with if sytax error, tried running using -x option n could not find any errors but when I run the same from cron I am getting Sytax error sometimes.
I used C shell to write below script and when I ran it from CRON it giving me below error

Your "cron" job on gpsprod3
/archive/SUPPORT/scripts/BUREAU/ALERTS/ALL/processCount/process_count.csh 102
produced the following output:
if: Expression syntax

Any help is much appreciated.

Script:
