Use whatever works for you, and it never hurts to be specific :)

There are so many ways of doing this .. here's another that we'd use to
mail out accounts to members monthly, from text files generated by some
php and mysql magic on another box, by another guy.
Note that this is enforced to be run by user 'subs' (here uid 996), so
that's who these messages are 'From:'. A script run from cron need not
be so paranoid about checking things .. this was hand-run 'when ready'.
#!/bin/sh
# sendacts 7Jan00 smithi .. mail out SubsBot messages .. cleanup 2Oct02
# each *.act file begins with To:, Cc:, X-mailer: etc lines
maildir="/home/subs/bills/$1" # preexisting dir as parameter eg '2000-01'
mailrun="./command.txt" # perline format: 'sendmail -t < userX.act 2>&1'
if [ "`id -u`" != "996" ]; then
echo "$0 must be run as user subs .. 'su subs' and retry .."
elif [ "$1" = "" ]; then
echo "usage: $0 directory"
elif [ ! -d $maildir ]; then
echo "$maildir does not exist .. mkdir first, unpack zipfile there"
elif [ ! -w $maildir ]; then
echo "$maildir is not writeable .. an older locked one, perhaps?"
else
cd $maildir
if [ ! -f $mailrun ]; then
echo "can't find ${maildir}/${mailrun} .. zipfile not unpacked?"
elif [ -f ./mailout.done ]; then
echo "'rm ${maildir}/mailout.done' if you wanna repeat mailout?"
else
umask 27
echo "$0 sending mail:" ; cat $mailrun
. $mailrun
touch ./mailout.done ; echo "$0 done"
exit 0
fi
fi
exit 1
with ./command.txt containing a line per recipient such as:
sendmail -t < user1.act 2>&1
sendmail -t < user2.act 2>&1
[..]
sendmail -t < userN.act 2>&1
and with the *.act files beginning such as:
