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
|
|
modify them.
|
|
On an x86 system, the ar applet adds about 1K.
|
|
|
|
Unless you have a specific application which requires ar, you should

|
probably say N here.
