915	bash psconfig --list has very unintended consequences, including messed-up path	jester@…	eugene	"psconfig.csh has a great number of useful options. psconfig.bash apparently only allows --help or a version number; trying psconfig.bash with the --list argument leads to all kinds of unexpected behaviour, including a messed-up path that doesn't find ls any more.

The logic is something like: I do psconfig, but I don't know what versions are there (~/.psconfigrc points PSCONFDIR to /IPP/psconfig/).

jester@aida77 ~$ alias psconfig='source /IPP/psconfig/psconfig.bash'
jester@aida77 ~$ psconfig
PSCONFDIR is not set : run psconfig with an argument to setup
PSVERSION is not set : run psconfig with an argument to setup
ARCH is not set : run psconfig with an argument to setup
PSCONFDIR: Undefined variable.

So I try psconfig --list to see what I can do... 

Here's what happens (with set -x):

++ PSCONFIG_DIR=/IPP/psconfig
++ ((  1 == 0  ))
