`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 *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.

`-R'
`--recursive'
     Recursively change permissions of directories and their contents.
