Okay, the documentation online at www.php.net/manual say that exec() will
run a system command and return the unix integer result code.  passthru()
will do the same thing but echo the output of the command to the screen.

Typically, I like to use passthru() for development so I can better track
bugs, and then replace passthru() calls with either system() or exec().

hi
thanks for the reply.
As you said i had only two commands in the script file
pwd,ls -laF. But still the output is 127 with no text printed to the screen.
when i tried seperately through 'passthru()' i am able to get the output.
testscript.sh
--------------
pwd
ls -laF

phpfile.php
--------------
<?
passthru("testscript.sh", $result);
echo $result;
?>
Output:
***************************
127
***************************
regards
arun
