- PROGRAM:
-
- fcpio -- a fast cpio for seekable devices
-
-
- SYNOPSIS:
-
- fcpio [-options] archive-name [extract-pattern1 [ ... extract-patternn]]
-
- Options implemented to date:
-
- x - extract files
- t - table of contents
-
-
- DESCRIPTION:
-
- fcpio is a partial cpio (tm Ma Bell) replacement. It is very useful
- when performing extracts or retrieving a table of contents from a
- disk-resident cpio archive. This is due to use of seeks to skip over
- unwanted data. (Our copy of cpio reads through everything as it must
- assume it can't seek.) Thus, a -t on a 3.3 Meg file runs at output
- (9600 baud) speeds with fcpio but has long pauses with cpio at all the
- long (> 20K) files within the archive. An extract of a few items is
- also very fast.
-
- The extract patterns do not support wild carding or anything fancy --
- fcpio will extract any files that begin with one of the extract patterns
- (or all files if no extract pattern is specified).

- BUGS:
-
- 1. Does not support non-seekable devices (like pipes?)
- 2. Does not maintain the files original magic number, UID or GID.
- 3. May not handle garbage at the end of the archive terribly well.
- (Our cpio puts an item called "TRAILER!!!" at the end, so fcpio
- equates that with EOF as well as ending on EOF. Other cpios
- may behave differently....)
