change de current working directory of my session...

[david_cantin]

Hi,

Is it possible to run a perl script that change my current "session"
working dir? Something like a script that a thing like thar :

$pwd
/home/foo
$./perl_script
$pwd
/usr/local/bin

it's dificult because a new process is started when we run a perl
script, so if the perl script change the cwd, the change will die with
the script...

Ps, My os is AIX 4.3 and 5.2

Running the script with a "dot space" before it causes it to run in
the current shell. In other words:

.. ./perl_script

(That's: dot space dot slash ... Those dots are hard to see on the
screen)

where did you get that strange notion? perl is not shell and that runs
shell code in the current shell. how could a shell run perl code inside
itself?

Sure, the dot is short for the shell "source" command.
The only question is: how would a shell interpret a Perl script?

You're forgetting some very important things:
1) It's ". bash_or_sh_script" for some shells,
2) It's "source csh_or_tcsh_script" for other shells,
3) Neither example above handls perl scripts.
