How to fix error msg: unknown test operator

[6656]

Hi all,

If I give multiple positional parms to a ksh script, I will get a error msg 'unknown test operator'. For example:

$> my_script_name A101 B101 B103
My script can work OK with capture $1 $2 $3 values.

But how fix it without error msg 'unknown test operator'.

Thanks,
Mike

Hi Mike,

My guess is that somewhere in the script my_script_name there is a mis-constructed test or if statement that is dependent on some or all of the input parameters. Please post your script or the relevant part of it, for further help.

I hope that helps.

Hi Mike,

Here is a test script.

-------- my_script_name --------
#!/usr/bin/ksh

for parm in $*
do
echo " this is parm = $parm ."
done
;;

exit 0
---------------------------------------

Thanks,
Mike

Thanks Mark and PHV,

I have found the error in my script.

if [ x$* = x ]; then .... This causes error while more than one parameters provided.

Add quote around the values can fixes the error.
if [ "x$*" = "x" ]; then ....

Why not simply test $# ?
Anyway posting the real code raising the error would make the solving faster.

Hope This Helps, PH.
