==: A test command parameter is not valid

[p7]

hi all

im getting this in a script from a vendor, they re looking into it.

in the meantime i was curious, what does that error means if the

script is checking for the OS:

if [ "`uname`" == "OS400" ]
then

it sees that its hp-ux but then gets the error mssg in the subject

thx in advance

What shell (if any) is referenced at the start of the script?

e.g.

#!/usr/bin/sh

#!/usr/bin/ksh

#!/usr/bin/csh

#!/usr/local/bin/bash

Which on HP-UX at least would be the POSIX shell, Korn shell, C Shell or GNU bash shell (if installed)

The [ xxx == yyy ] construct is bash shell syntax if I recall corerctly... if the vendor is trying to be portable, one would imagine he would use POSIX standards, which implies using:

if [ "`uname`" = "OS400" ]

which has the advantage of working in POSIX, Korn and bash shells...
