| 12 | ar is an archival utility program used to create, modify, and
|
|---|
| 13 | extract contents from archives. An archive is a single file holding
|
|---|
| 14 | a collection of other files in a structure that makes it possible to
|
|---|
| 15 | retrieve the original individual files (called archive members).
|
|---|
| 16 | The original files' contents, mode (permissions), timestamp, owner,
|
|---|
| 17 | and group are preserved in the archive, and can be restored on
|
|---|
| 18 | extraction.
|
|---|
| 19 |
|
|---|
| 20 | The stored filename is limited to 15 characters. (for more information
