Hi All,

I have a script to convert a file and output the filename with "_output", however it not work. Can help?

echo Please input list file name:
read listn
for file in `cat $listn.txt`
do
convert $file > $file_output

Thanks all!!

Use:

convert $file > ${file}_output

instead, supposing that "convert" is a funcion/program/whatever which outputs what you want insisde the new file.

To sum up, use ${file}_output instead. :slight_smile:

Regards.
