Off the top of my head:

#!/bin/sh -e

sed -e '/^Subject: /!d; s/^Subject: //' /var/spool/mail/sms  ${smsfile}

:/var/spool/mail/sms

xargs -L1 /usr/bin/gammu --sendsms TEXT  ${smsfile}

mv -f ${smsfile} ${smsfile}.bak
8

No loops necessary.

By the way, what's gammu, and why is it in /usr/bin ?

Actually, some functionality was lost in the above translation, let me add the
missing functionality back-in...

#!/bin/sh
spoolfile=/var/spool/mail/sms
awk -v pat=^Subject:  '
BEGIN { found = 0 }

sub(pat, )

   ***, FILENAME, ***
exit ! found
}' $spoolfile  :  $spoolfile


 Or, as a shell One-Liner (compatible with any shell and any awk)...

The above doesn't translate so-well into a one-liner (unless you can stomach
really long lines 80 chars), but here it is...

awk -v pat=^Subject:  'BEGIN{found=0}$0~pat{found++;sub(pat,
);print|/usr/bin/gammu --sendsms TEXT $1}END{if(!found)printf %sSorry the
