Hi Jenda,
Thanks for replying. Trimming the PATH is the last resort. I wanted to know if
there is a cleaner way of doing things. Actually the PATH is indeed needed. I
can trim it and then restore it at the end of the perl script (the problematic
script that is ) because things downstream in our applications have a
dependency on the PATH so cant risk fiddling with it.
Thanks,
Sumit

6000 characters long PATH? Either you have some very very long paths
or way too many directories. Are you sure you need to have them all
there? Really?
There is a limit to the total size of the environment and I really do
not think you can get around that. Except for trimming down the %ENV
before starting anything. I do think you should trim down your path
for the whole system though.
