system ("shellscript"); - question

[subotai]

Greetings!

Environment: linux, perl interpreter, browser.
I want to run a shell script from a perl script in my browser.
Dont i do this with 'system ("shellscript"' ?
Works with things like ("touch test.txt&quot, but it does not execute my shellscript.
Any ideas?

thank you in advance,
Subotai

If the script that you are trying to call is not in a directory that is defined in your $PATH environmental variable then the system() call won't be able to find the file. You will need to specify a relative or absolute path when you call the file.

ex.
system("./myscript.pl" # if the file is in the same directory as the calling script.
or
system("/home/mrwizzard/perlscripts/myscript.pl"
# using absolute path

jaa

Hello Justice41!

I've taken into account your information, but it still wont exec. Tried the same with system ("touch /PATH/something" and it worked.

I've set all the scripts rights to x, r and w, owner to root, and the webserver has root access rights. Cant really figure out what is wrong.

If you can think of anything else, i would greatly appreciate it!

thanks anyway, and greetings,
Subotai

I hope that machine is not on a network.
You're really inviting disaster.
You should never give a web server root permissions.

Might be something internal to the shell script.
The shell script will be running as the web_server daemon. If there is anything for which the shell script lacks sufficient path info or permissions, the shell script will fail.

Can you post a little concise code? 'hope this helps

Try executing the code from the tick with backticks instead.

`shellscript.sh`

also, just for debugging, change the premissions of 'other' to rx.

chmod o+rx shellscript.sh

And, I know this is basic but I have to ask, the script works when you run it from the command line, yes?
