chmod [ -R ] [ +-= ][ wsha ] fpsec ...
If -R is specified, then chmod recursively descends subdirectories looking for matching files. The -R flag is compatible with the AIX and the original Unix versions of chmod.
The first argument must contain exactly one of the ``+-='' file
mode operators followed by one or more of the ``wsha'' file
mode letters, with no intervening spaces.
One or more file specifications must follow. A file specification consists of some combination of drive, path, and filename. The filename may contain Bourne shell pattern-matching characters.
The file mode operator can be one of the following:
| + | Sets the specified file mode(s). |
| - | Resets the specified file mode(s). |
| = | Sets the specified file mode(s) and clears the modes that aren't specified. |
The file mode letters have the following meanings:
| w | Write permission. |
| s | System attribute. |
| h | Hidden attribute. |
| a | Archive attribute. |
