| - | help |
| - | ar is an archival utility program used to create, modify, and |
| - | extract contents from archives. An archive is a single file holding |
| - | a collection of other files in a structure that makes it possible to |
| - | retrieve the original individual files (called archive members). |
| - | The original files' contents, mode (permissions), timestamp, owner, |
| - | and group are preserved in the archive, and can be restored on |
| - | extraction. |
| - | |
| - | The stored filename is limited to 15 characters. (for more information |
| - | see long filename support). |
| - | ar has 60 bytes of overheads for every stored file. |
| - | |
| - | This implementation of ar can extract archives, it cannot create or |
