I had an issue with permissions. I needed a backup of this command. Here it is. Not only a backup but a share too. Make sure you share too.

chown - change file owner and group
chown [OPTION]... [OWNER][:[GROUP]] FILE...
chown [OPTION]... --reference=RFILE FILE...
This manual page documents the GNU version of chown. chown changes the user and/or group ownership of each given file. If only an owner (a user name or numeric user ID) is given, that user is made the owner of each given file, and the files' group is not changed. If the owner is followed by a colon and a group name (or numeric group ID), with no spaces between them, the group ownership of the files is changed as well. If a colon but no group name follows the user name, that user is made the owner of the files and the group of the files is changed to that user's login group. If the colon and group are given, but the owner is omitted, only the group of the files is changed; in this case, chown performs the same function as chgrp. If only a colon is given, or if the entire operand is empty, neither the owner nor the group is changed.

Change the owner and/or group of each FILE to OWNER and/or GROUP. With --reference, change the owner and group of each FILE to those of RFILE.

-c, --changes
like verbose but report only when a change is made
affect the referent of each symbolic link (this is the default), rather than the symbolic link itself
-h, --no-dereference
affect each symbolic link instead of any referenced file (useful only on systems that can change the ownership of a symlink)
change the owner and/or group of each file only if its current owner and/or group match those specified here. Either may be omitted, in which case a match is not required for the omitted attribute.
do not treat '/' specially (the default)
fail to operate recursively on '/'
-f, --silent, --quiet
suppress most error messages
use RFILE's owner and group rather than specifying OWNER:GROUP values
-R, --recursive
operate on files and directories recursively
-v, --verbose
output a diagnostic for every file processed

The following options modify how a hierarchy is traversed when the -R option is also specified. If more than one is specified, only the final one takes effect.

if a command line argument is a symbolic link to a directory, traverse it
traverse every symbolic link to a directory encountered
do not traverse any symbolic links (default)
display this help and exit
output version information and exit

Owner is unchanged if missing. Group is unchanged if missing, but changed to login group if implied by a ':' following a symbolic OWNER. OWNER and GROUP may be numeric as well as symbolic.

chown root /u
Change the owner of /u to "root".
chown root:staff /u
Likewise, but also change its group to "staff".
chown -hR root /u
Change the owner of /u and subfiles to "root"
