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 26. File permissions.
The program accepts the following options. Also see 2. Common options.
