thanks it works..

I also like to know i am getting some value into a variable using grep command

Code:

count_trlr=`grep "^3" $DATADIR/$FILE1.DAT| cut -c2-8`

After i get the value into variable i want to remove zeroes
eg: count_trlr=000004 but i want only the number 4 not zeroes like this, count_trlr=4

Code:

 
eg:
contr_trlr=0023343, i want 23343
contr_trlr=1111111, i want 1111111
contr_trlr=0222222, i want only 222222

how to do this in ksh script.

thanks in adv.
