I've written a function to print elapsed time similar to /usr/bin/time
but can be called at the beginning and end of a script from within
the script. Occasionally I get an error: '8-08: value too great for base'
It's caused by the difference in these 2 command strings but I can't for
the life of me see what's going on.

now='09:07:16'; startHr=${now%%:*}; startHR=${startHr#*0}; echo $startHr;
09

str=09; str=${str#*0}; echo $str;
9

Thanks,
Mike

Apparently bash is treating the number as octal because it starts with a
leading 0.

Did you mean to echo $startHR - capital 'R' - in the first one? That is
'9' as you are expecting ;)

Did you wand to echo startHR and not startHr in the first expression?

I do it like this
# Set date format
ISO_8601='%Y-%m-%d %H:%M:%S%z'


aptitude safe-upgrade
date "+System Upgrade Completed at: $ISO_8601">>/root/Admin/last-upgrade

the result is

Update started at : 2010-03-19 08:50:53-0400
