Date extraction using expr

[christiniaroelin]

Hi,
I was facing problems with executing the following code:
#! /bin/ksh
export stamp=${stamp-"`"(expr $(date"+%m") -1)"'"}
echo $stamp

please advice on the right syntax.

Thanks
Christinia

Try this...

#!/bin/ksh

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

Hope this helps.

Sam,
Thanks for your input..that worked fine..but i get the integer output. say instead of 06 the output is 6.i tried having a printf ..but wasnt successful.
Could you please advice on this

Change it to...

#!/bin/ksh

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

That forces [tt]STAMP[/tt] to be two characters, zero filled.

Hope that helps.
