with gawk I do it like this:

gawk 'BEGIN{print "your message here" > /dev/stderr }'

man gawk

No, the correct way is :-)
import sys
sys.stderr.write("your message here")

man python

ksh: print -u2 whatever
bsh: echo whatever 1>&2
Solaris or whatever system that has /dev/stderr or /dev/fd/2:
echo >/dev/stderr
Call Perl: perl -e 'print(STDERR whatever)'

Note that with recent versions of gawk, it actually writes to fd
2 (stderr), with older versions, your system had to have a
/dev/stderr device.

With Bourne like shell:

echo "your message here" >&2

With C shell:

sh -c 'echo "your message here" >&2'

With perl:

perl -le 'print STDERR "your message here"'

With sed, if your system has /dev/stderr or /dev/fd/2:

sed -e 'h;s/.*/your message here/;w /dev/fd/2' -e g

with ruby:

ruby -le 'STDERR.print "your message here"'

Python:

python -c 'import sys; sys.stderr.write("your message here\n")'
