Hello out there,

I have a problem using /bin/sh:

if I set the option -e  (stop execution if a command fails) I
can't use any if's, since writing

  if /bin/test [condition]
    then
    [commands1]
    else 
    [commands2]
  fi

never executes [commands2]. If the condition is true [commands1]
are executed, but if the condition is false, /bin/test returns
a value <> 0 and so the sh stops execution.

[Sorry, but test is not a builtin in /bin/sh on our VAX's running
ULTRIX and BSD4.3. In fact, in /bin/sh on our Suns, it is]

Any help?  Thanks in advance!

Bernhard
