Hi folks,

Works from the shell just fine (bash makethesite.sh username pathtoputfiles

Trying to execute this via php, and it literally does nothing.
If I try something like:
$bashoutput=shell_exec('bash makethesite.sh username pathtoputfiles pathtogetfiles');
echo $bashoutput;
I get nothing output, and the script doesn't execute.
I'm asuming you are executing something like the following:
php myPhpScript.php
The following will probably give you the desired results...
php -qC myPhpScript.php
This prevents PHP from switching out of the current directory.
HTH,

RE: [PHP] question about executing a bash shell script...
try something like:
$bashoutput=shell_exec('/usr/bin/bash makethesite.sh username pathtoputfiles
pathtogetfiles');
if that doesn't work can you use the system() function instead?

Re: [PHP] question about executing a bash shell script...
Hi Robert,
Thanks so much for the prompt reply.
Actually, I'm not trying to execute a php script, I'm trying to execute a
shell (bash) script.
This works at the command line:
bash makethesite.sh param1 param2 param3
This doesn't work via php
$bashresult=shell_exec('bash makethesite.sh param1 param2 param3');
echo $bashresult;
Doesn't execute the script, nothing in $bashresult

You are trying to execute a bash script from PHP though. When you invoke
the php engine it usually changes directory (to the root defined in the
php.ini I think). To stop this so that it will remain in the current
directory so that when you run bash it will see the bash script in the
current directory, you need to use the -C command line option. I believe
your environment is inherited by php and subsequently bash and so if
you don't use the -C option bash will be looking in the wrong directory.
Cheers,
Rob.

What does the php logs say? You should set error_reporting to E_ALL.
Any ideas?
The user that the webserver (assuming apache) is usually nobody or apache and
may not have the necessary permissions to execute your script. Also try
specifying the complete path to bash.
