[Calator]

Hi, in a ksh script need to test if argument passed on command line is numeric (integer). Thanks.

What have you got so far?

In the ksh man page take a look at the typeset builtin (-i).

Hope This Helps, PH.

For the korn shell:

function is_integer {
[[ $1 = ?([+-])+([0-9]) ]]
}

is_integer $i && echo "yes" || echo "no"
