This is really ugly, but ...
put the contents of the message you want to send in ./mymail.txt, and
for i in `cat /etc/passwd`
do
uid=`echo $i | sed -e "s/[^:]*:[^:]*:\([^:]*\).*/\1/"`
if [ $uid -ge 1000 ]; then
username=`echo $i | sed -e "s/\([^:]\):.*/\1/"`
echo -n "about to send mail to $username ... ..."
mail -s "my subject" $username < mymail.txt
echo "done"
fi
done 2>/dev/null
This is assuming, of course, that your system follows the debian
convention of making all uid's >= 1000 normal users, and all <=1000
special users (www, root, mysql, mail, etc.)
Someone make me feel embarassed by posting a much more beautiful script.
At the very least, replace those sed lines with awk or something. It
should be much easier to say "grab the first and third field split by
:'s" than that ugly regexps above.
