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 mildy amusing for the
unwary.
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.
