Eric Andersen53601822002-12-05 21:12:42 +0000[diff] [blame]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

22 ar has 60 bytes of overheads for every stored file.

25 modify them.
