Re: Could someone look at my problem in shell-exec?

Thank you very much for your great help. I am trying to put my tar file into /tmp directory which is available to all users and return it to the user. $output=`cd /tmp; tar cvf output.tar $home/www/1989/01/01.txt; ls; tar uvf output.tar`; echo<pre>$output</pre>; This time, the webpage list the files in tmp including the tar file. However, it is not the /tmp which I see from server. I have no idea which directory it opened. Meanwhile, it cannot tar uvf output.tar. Do you think it is because php did not understand the path and alias of my machine? What exactly /tmp it refer to? Should I input the whole path from the root? Thank you again. --- Ernest E Vogelsinger <ernest@vogelsinger.at> wrote: > At 22:34 22.05.2003, love jiangnan said: > --------------------[snip]-------------------- > >All the files are under my own directory and > created > >by myself. > > > >could you tell me how can I give user permission? > Or > >should I talk to admin to give user permission? > --------------------[snip]-------------------- > > Create a subdirectory in your home directory, e.g. > "webcache".
