Hi all.

I´m trying to execute a shell script from a php program but
texexec gives me an Error.

As it says, pdfetex can't write to its logfile.  Odds are pdfetex is
running as whatever user the webserver is, whether that's "web" or
"nobody" or whatever.

A nice way to handle that is to carefully create a uniquely-named
directory in a temp directory like /var/tmp.  Then you can make sure
that all of your commands are executed in that new temporary
directory.  

For example, the shell command would be something like this once
you've made the temp directory "/var/tmp/aaa4172":

    sh -c '(cd /var/tmp/aaa4172 && texexec test3)'

Ok.. The problem was an old logfile.with wrong perms that was interfering
with the new "nobody" logfile.
Stupid me..
But now everything works and i´m wery happy.
