Question : Mod calculations and "bad number "

1: 2: 3: 4:

MINUTE=`date +"%M"` MINUTE_MOD=$((MINUTE%15)) ]

Most of the time, the above works nicely.

Until you get to the start of the hour.....

08: bad number `08'

09: bad number `09'

Where am I going wrong ?

Answer : Mod calculations and "bad number "

OK,

OpenBSD has its own reimplementation of the Bourne shell, which I'm not really familiar with.

But nevertheless, my suggestion

MINUTE=${MINUTE##0}

should work in that shell.
