Hallo everybody

I am having a shell script called auto_run.sh in that only the first line works.
the second line which has sed command is working only at the # prompt. not within the shell script. What could be the reason.

*... sed 's/ //g' KTI >abc works in another shell script without the first line.when i add the exec....statement it stops working. Please can anyone help me.Thanks


exec auto_inv.4ge >KTI
sed 's/ //g' KTI > abc
exit
