Chown

- The title of this article is incorrect because of technical limitations. The correct title is "chown".
The chown command is used on Unix-like systems to change the owner of a file. In most implementations, it can only be executed by the Superuser. Unprivileged (regular) users who wish to change the group of a file that they own may use chgrp.

Usage
The general syntax for the chown command is:
chown [user][:group] target1 [target2 ..]
- The optional user parameter indicates the new user who should take ownership of the targets.
- The optional group parameter (which must be prefixed with a colon, :) indicates the group with which the targets should be associated.
- The target parameters indicate the files or directories for which the user and/or group will be changed.
Footnotes
- One of either user or group must be specified. The chown command will not execute properly without at least one of those parameters.
- The user and group parameters can be either symbolic names or identifiers (i.e. a User ID or Group ID).
Usage examples
# chown root /var/run/httpd.pid
- Change the owner of /var/run/httpd.pid to 'root' (the standard name for the Superuser).
# chown nobody:nobody /tmp /var/tmp
- Change the owner of /tmp and /var/tmp to 'nobody' (the standard name for Nobody).
- Changes the group associated with the same targets to 'nobody' (the standard group corresponding to Nobody).
# chown :512 /home
- Change the group identifier of /home to 512 (regardless of whether a group name is associated with the identifier 512 or not).
