Eric Andersen53601822002-12-05 21:12:42 +000012 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
Glenn L McGrath0337c462002-12-06 22:40:54 +000018 extraction.

Glenn L McGrath0337c462002-12-06 22:40:54 +000020 The stored filename is limited to 15 characters. (for more information
21 see long filename support).
22 ar has 60 bytes of overheads for every stored file.

24 This implementation of ar can extract archives, it cannot create or
25 modify them.
Eric Andersen6d3c7e72003-08-22 21:15:07 +000026 On an x86 system, the ar applet adds about 1K.

29 probably say N here.

Eric Andersene5642112003-07-14 19:37:08 +0000250 unzip will list or extract files from a ZIP archive,
251 commonly found on DOS/WIN systems. The default behavior
252 (with no options) is to extract the archive into the
253 current directory. Use the `-d' option to extract to a
254 directory of your choice.

283 This allows dpkg and dpkg-deb to extract deb's that are compressed internally
284 with bzip2 instead of gzip.
