Where To Find Other Unix Calls?

[ohh]

This should be simple enough to answer, I hope. I'm in the process of moving my site over to TCH. It has a fair amount of CGI calls buried in it: most of it very low-level and straightforward, but there are a couple of scripts which call on other parts of UNIX for help.

 

I've got the paths for Perl and sendmail - they're hard to miss, being listed on the main page of CPanel and all. What are the paths for rm, date and ls?

 

I'm guessing just /bin. But, er, I'd rather not guess. Thanks!

Welcome to the forums, ohh!

 

You should not need a path to execute rm, date and ls. Just write your script to do the following:

 

>rm /path-to-files
date
ls /path-to-list

[ohh]

Is this true for a Perl script running from /scgi-bin as well? On the last two servers I was on, for Perl scripts that ran as setuid, Perl considered the $PATH environment variable as potentially tainted - and so Perl would reject it, meaning I had to call rm, date and ls with full paths.

 

This is normal behavior for setuid'd Perl, or at least it was when I learned it. Of course, that was a few incarnations of Perl ago.

Well if that's the case then use /usr/local/bin/ to preface the commands.

Excellent. Thanks very much!

Well if that's the case then use /usr/local/bin/ to preface the commands.

 

Uhm, could we double-check this? date seems to be located at /bin/ - at least, it functions there but doesn't at /usr/local/. I'm not yet sure about rm and ls.

Please open a ticket with the help desk and one of the techs will tell you for sure.
