[SOLVED] Using awk to iterate through list of files?

Issue

I'm pretty unfamiliar with awk, but I am looking for a way to iterate through all files in a directory and execute a simple awk command. My command is a simple substitution that replaces all tabs with two spaces.

awk '{gsub("\t","  ");print}'

How can this be extended to loop through a directory and execute the command on all files?

Solution

Pass the files to awk on the command line of course:

$ awk 'program' *

But probably it is easier to use

$ perl -pe 's/\t/  /g' *

Or, if you would rather have an in place edit, simply:

$ perl -i.orig -pe 's/\t/  /g' *
