client asked <\/p>\n

Hey all… I need to run a shell script on Zoo via PHP, and was<\/span>
trying to use the PHP exec() function.<\/span>

The script will manipulate some images using ImageMagick. Everything<\/span>
works fine when calling the script from the command-line. I’m having<\/span>
trouble, however, running it via PHP<\/span>

The .sh file is owend by the account that the PHP file resides under.<\/span>

What should the path to the shell script be (relative vs. absolute),<\/span>
and will I encounter any issues trying to use exec() once my path is<\/span>
correct?<\/span><\/div>\n

Best to use absolute path, so there is no ambiguity<\/p>\n

Best to use alias of your script’s folder. In general, any users alias is formed using the convention<\/p>\n

    \/users\/x\/y\/xyzzzzz<\/p>\n

where x is the first letter of the use’rs NetID, y is the second letter of the user’s NetID, and xyzzzzz is the user’s netid.<\/p>\n

here’s an example. No issues for me running this in my home directory<\/p>\n

#!\/usr\/local\/bin\/php
<?
passthru("\/users\/w\/a\/waw\/mysqltest.pl");
$dog=exec("\/usr\/bin\/date");
print "dog=$dog";
?><\/p>\n

except he meant to run it via http:\/\/www.uvm.edu\/<\/p>\n

I sugegsted he try cgi.uvm.edu — no SAFE mode there<\/p>\n","protected":false},"excerpt":{"rendered":"
