Marc Mutz sent a mail saying for starters, that inspired me, i like to use
the "kiss" method, keep it simple, The last word is not for resale, however,
Marc, your idea possably wont work, (forgive me for saying that)
should the date not be,
$(date +'%Y%m%d%H%M') ??
which should produce the same amount of numbers as the Expire line above.
I would do it in such a way.
#!/bin/sh
DATE=`date +%Y%m%d%H%M`
THERE=`cat filename | grep Expires:200005281430 | awk -F : '{ print $2 }'`
if [ ! "$DATE" -gt "$THERE" ]; then
echo "The date has past Expire time."
else
echo "Date is $DATE and FILE = $THERE"
fi
Of course i am going on the principle that the expire time is to be found
in the file "filename".
You would need to subtitute the "echo's" with whatever you want,
Eg;
rm /path/to/filename
else
bla bla.
fi
The above is also for starters, i do however like the way Marc's script
works.
Or should work as i see it when one adds the hour and minute to the date
line.
Marc. ???
We chould get a reaction from California later on when the Olszewski's wake
up.
