As Sakari Jalovaara wrote: > It struck me as a rather nice idea. No more "ps | grep sendmail ... > kill ... sendmail -bd -q1h" - just do "nanny restart sendmail". All `conforming' daemons leave their PID in /var/run/<name>.pid. Thus, restart.sh: #!/bin/sh if [ $# -ne 1 ] ; then echo "usage: $0 <daemonname>" >&2 exit 64 fi if [ -f /var/run/$1.pid ] ; then # the head -1 is only needed for sendmail, but doesn't hurt pid=$(head -1 /var/run/$1.pid) if [ "X$pid" != X ] ; then echo "Sending SIGHUP to PID $pid..." kill -HUP $pid exit $? fi fi echo "/var/run/$1.pid doesn't exist or is empty" >&1 exit 72 -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
