chmod: Change access permissions

chmod changes the access permissions of the named files. Synopsis:

chmod [option]... mode file...

chmod never changes the permissions of symbolic links, since the chmod system call cannot change their permissions. This is not a problem since the permissions of symbolic links are never used. However, for each symbolic link listed on the command line, chmod changes the permissions of the pointed-to file. In contrast, chmod ignores symbolic links encountered during recursive directory traversals.

The first non-option argument, mode, specifies the new permissions. See the section below for details.

The program accepts the following options. Also see section Common options.

`-c'
`--changes'
Verbosely describe the action for each file whose permissions actually changes.
`-f'
`--silent'
`--quiet'
Do not print error messages about files whose permissions cannot be changed.
`-v'
`--verbose'
Verbosely describe the action or non-action taken for every file.
`-R'
`--recursive'
Recursively change permissions of directories and their contents.
