Sorry, I copied an old script, and here is a bit more simplified error
check. Only test error-status "$?" is needed.
#!/bin/ash
readsensor () (
VAL=`owread -s 3002 $1/$2 2>&1`
ERR=$?
[ $ERR != 0 ] && {
date >>$DEBUGFILE
echo >>$DEBUGFILE "ERROR: owread $1 failed 1st time: $VAL"
VAL=`owread -s 3002 $1/$2 2>&1`
ERR=$?
[ $ERR != 0 ] && {
echo >>$DEBUGFILE "ERROR: owread $1 failed 2nd time: $VAL";
false; return;
}
}
# save last value to a file as well (mostly for web-server)
[ "$2" = "temperature" ] && echo "$VAL" > /tmp/last_val.$1.$2
echo "$VAL"
true;
)
writesensor () (
VAL=`owwrite -s 3002 $1/$2 $3 2>&1`
ERR=$?
[ $ERR != 0 ] && {
date >>$DEBUGFILE
echo >>$DEBUGFILE "ERROR: owwrite $1/$2 $3 failed 1st time."
VAL=`owwrite -s 3002 $1/$2 $3 2>&1`
ERR=$?
[ $ERR != 0 ] && {
echo >>$DEBUGFILE "ERROR: owwrite $1/$2 $3 failed 2nd time.";
false; return;
}
}
true;
)
VAL=`readsensor $SENSOR PIO`
ERR=$?
[ $ERR != 0 ] && exit 1
