Hello

My PHP script executes many bash/cmd commands.
Functions like "exec()" or "system()" cause that new bash/cmd session
is started,
the command is executed and the session is closed. Unfortunately
it is very slow process so I would like to increase performance and
open one bash/cmd session on the begin of my script and execute
the commands such as in normal system opened bash/cmd window and close
it
at the end of my PHP script.
Does anybody know whether and (if yes) how can I do that?

PS. I need the retrieve informations from previous command before
executing next command because next command is strongly dependent on
the
results from previous command.

Best regards
Melmack
