I would like to make sure that a script or program is not executed during a certain period of every hour. Is there an elegant method to achieve this, short of an additional C program? Eric

If you can blow off the positional args: set -- `date` case $4 in *:0[0-4]:* ) echo "Bad time to run this" exit 1;; esac If you can't, you'll need to save and restore them, or run this in a subshell (within parens) and check the exit status.

The following shell will exit if it is between 10 and 15 minutes past the hour (inclusive). start=10 end=15 time=`date +%M` if [ $time -ge $start -a $time -le $end ]; then echo "you can't do this now" exit fi echo ok to run -- Conor P.

The "date" command can be made to give you any selected date or time info with a format string. e.g. date +%M prints the minutes (check-out the man page!). Thus to block operation between say 20 & 40 mins past each hour: minmins=20 maxmins=40 mins=`date +%M` if expr $mins \> $minmins \& $mins \< $maxmins > /dev/null then echo No dice exit 1 fi Adjust the logic to suit. -- Rick Jones The definition of atomic: Tetra Ltd. from the Greek meaning "indivisible" Maidenhead, Berks, UK So what is: rick@tetrauk.uucp an atomic explosion?
