Check for numeric result

[dickiebird]

Guys
Any way I can check / force a numeric result ?
Given :

typeset-i seconds
seconds=`lsuser -a time_last_login $user|cut -d"=" -f2|cut -c1-10`

I need to check $seconds > 0 , but if the result of lsuser is blanks/nulls/spaces, then the script returns :

0403-009 The specified number is not valid for this command.

Any thoughts?
TIA ;-)

I got it meself !
I check the output of the lsuser is > 8 characters (means the attribute is set) and has a value - then do the cutting of those valid values as opposed to cutting nothing / null / space.
Doesn't answer my question - but at least it works now. Dickie Bird
