I have a folder full of text files named 000.txt to 181.txt. How can I process all of them with the same awk script (program.awk) and send them to their respective output files (output000.txt - output181.txt)?

for f in ???.txt
do
awk -f program.awk "$f" > "output$f"
done
will process all files whose names are three characters (any characters)
followed by .txt. To restrict it to only files whose names
are three digits followed by .txt, use
for f in [0-9][0-9][0-9].txt

Do I need to type this command on the command line? for f in ???.txt do awk program.awk "$f" > "output$f" done– amatekApr 25, 2015 at 3:01

You can type it as four separate lines, as I showed it. But, if you want to type it all on one line, you need to add semicolons, as in
for f in ???.txt; do awk program.awk "$f" > "output$f"; done. Apr 25, 2015 at 3:07 -

It worked. How about processing all the .txt files in the folder, despite the number of characters in the file names?– amatekApr 25, 2015 at 11:45

@G-Man; I wonder why your code would work (as the OP says); the
awkcall is lacking the-fswitch!– JanisApr 25, 2015 at 13:34
