Top Forums Shell Programming and Scripting Apply 'awk' to all files in a directory or individual files from a command line Post 302469109 by Corona688 on Thursday 4th of November 2010 06:50:29 PM

awk does not run inside your shell, hence cannot set shell variables. If you want to get a value out of awk, you have to print it somehow. Since you're already using stdout for data, maybe stderr?

Code:
END { print "max is", $max > "/dev/stderr"; }
