expr - date issue

[christiniaroelin]

Hi,
Im facing the following issue while running the below script:
output from the script : 0 6
required output : 06

#! /bin/ksh
export stamp=${stamp- "$(printf $(expr `date '+%m'` - 1 ))"}
echo $stamp

if [ $month -lt 10 ]
then
export stamp=0$stamp
fi

print $stamp

Please advice on the above.
Thanks!!

See thread822-1098239 for answer.

Hope this helps.

#!/bin/ksh

typeset -Z2 STAMP
export STAMP=${STAMP-$(expr `date '+%m'` - 1)}
print $STAMP

This will output "[tt]06[/tt]".

Hope this helps.

What happens in January? Is "[tt]00[/tt]" an acceptable value?

If not, change it to...

#!/bin/ksh

typeset -Z2 STAMP
export STAMP=${STAMP-$(expr `date '+%m'` - 1)}
(( ! STAMP )) && STAMP=12

print $STAMP

Hope this helps.
