REVOUTPUT(3am) GNU Awk Extension Modules REVOUTPUT(3am) NAME revoutput - Reverse output strings sample extension SYNOPSIS @load "revoutput" BEGIN { REVOUT = 1 } # Reverse all output strings DESCRIPTION The revoutput extension adds a simple output wrapper that reverses the characters in each output line. It's main purpose is to show how to write an output wrapper, although it may be mildly amusing for the un- wary. EXAMPLE @load "revoutput" BEGIN { REVOUT = 1 print "hello, world" > "/dev/stdout" } The output from this program is: dlrow ,olleh BUGS This extension does not affect the default standard output.
