os.chown()

Hey everyone. I tried to use os.chown() in the following manner:

os.chown('filen ame', 'username', 'groupname')

I got an error, and when I googled for this function I realized that I
must pass the numerical uid and gid. My question is, is there a way for
me to change ownership based on the name instead of the number? Perhaps
there's a function that will let me lookup the uid from the username,
and the gid from the groupname?

Thanks :)

James

You want pwd.getpwnam and grp.getgrnam.

One way is:
os.system( 'chown username:groupn ame filename')

Are you doing this as root? The chown function is usually restricted to
root.

Hi ! The entire (PHP-) world seems to have the same problem: Many providers let you upload as one user, lets say "ftpuser", yet then apache and your script will run as another user e.g. "nobody" Allways the same trouble: You would need to chmod your entire website by ftp-client/telnet, to have things like a php-based file-editor work...

Sorry to crosspost, but I have no idea if this is more a PHP question of general Linux question. I have a script that makes changes to image files, montages them into a jpg, and creates a Web page with that image. It starts with someone from our graphics dept. who I set up to copy the image files over to the Linux server with SAMBA. The files gain the owner/group of "nobody" and permissions of 744.

I have a form handler script that creates a new folder for the files sent in the form. Move_uploaded_file transfers then puts those files there. But problem is that apache becomes automaticly owner of folder and files, so later I cannot delete/rename/transfer those files trough winscp. Only load them if permissions are set ok. Chown doesn't work, because only superuser can change file's owner. What can I do? Make 24 h agreement with...

This has probably been answered a million times, but I can't seem to find the answer. How can I change the owner of a directory using a Perl command? I know chown can be used with files, but it doesn't appear to work with directories. Thanks in advance, Frank

I just made a simple program to create files; I'm trying to get the hang of basic file manipulations. Whatever file my program makes, the owner of the file is "www-data," so I can't edit it using my regular server user. I can use root to change the ownership to the server user, but I don't want to do that for every file. That's why I tried to use chown() to give ownership to the server as soon as the file is made, but I get this error: ...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
