Linux chown命令详解
chown将指定文件的拥有者改为指定的用户或组，用户可以是用户名或者用户ID；组可以是组名或者组ID；文件是以空格分开的要改变权限的文件列表，支持通配符。
chown常见命令参数
Usage: chown [OPTION]... [OWNER][:[GROUP]] FILE...
or: chown [OPTION]... --reference=RFILE FILE...
Change the owner and/or group of each FILE to OWNER and/or GROUP.
-c, --changes like verbose but report only when a change is made
--dereference 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)
--from=CURRENT_OWNER:CURRENT_GROUP
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.
--no-preserve-root do not treat `/' specially (the default)
--preserve-root fail to operate recursively on `/'
-f, --silent, --quiet suppress most error messages
--reference=RFILE 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.
-H if a command line argument is a symbolic link
to a directory, traverse it
-L traverse every symbolic link to a directory
encountered
-P do not traverse any symbolic links (default)
--help display this help and exit
--version output version information and exit
Examples:
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".常用的命令展示
