I am trying to run a script every second. I set up two scripts:
first script (the one that does the work)
#!/bin/ash
update() {

trap 'update' HUP
mknod /tmp/dummyfifo p
while true; do
read < /tmp/dummyfifo > /dev/null 2>&1
done
and now the trigger script:
#!/bin/ash
/bin/watch -t -n 1 killall -HUP update > /dev/null 2>&1
The problem is that the 'read' generates a
/usr/bin/update: line 1: can't open /tmp/dummyfifo: Interrupted system
call
every time watch triggers the script. Other than that it works
perfectly.
I've tried various other things but this works best, except for the
system call clogging up the terminal and logfiles.
Here's what works:
trap 'update' HUP
mknod /tmp/dummyfifo p
cat /tmp/dummyfifo &
pid=$!
while true; do
wait $pid
done
