HI!

Iam running two scripts in my unix server

First script is Splitting a file containing 300 records each with .tmp extension

for eg Z_PRICE_NEW.tmp

Second script is converting .tmp to.txt

for file in Z_PRICE_NEW_2*.tmp ; do mv $file `echo $file |sed 's/\(.*\.\)tmp/\1txt/'`;done

The problem is iam putting these scripts in a job and running them

If the file is empty the first script is not generating an file like Z_PRICE_NEW.tmp and completing .second script is searching for this file and if there is no such file it is aborting ,

Can any one tell me how to stop second script from aborting even if ther is no file.

Code:

file_lst=`ls Z_PRICE_NEW_2*.tmp 2>/dev/null`
if [ $? -eq 0 ]; then
	echo "$file_lst" | while read file ; do mv $file `echo $file |sed 's/\(.*\.\)tmp/\1txt/'`;done
