`chmod': Change access permissions
==================================
`chmod' changes the access permissions of the named files. Synopsis:
chmod [OPTION]... {MODE | --reference=REF_FILE} 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.
If used, MODE specifies the new permissions. For details, see the
section on Note:File permissions.
The program accepts the following options. Also see Note: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.
`--reference=REF_FILE'
Change the mode of each FILE to be the same as that of REF_FILE.
Note:File permissions. If REF_FILE is a symbolic link, do not
use the mode of the symbolic link, but rather that of the file it
refers to.
`-R'
`--recursive'
Recursively change permissions of directories and their contents.
