Copy to/from archives - orig FSF source.
.description
Cpio copies files into or out of a cpio or tar archive, which is a
file that contains other files plus information about them, such as
their pathname, owner, timestamps, and access permissions. The
archive can be another file on the disk, a magnetic tape, or a pipe.
Cpio has three operating modes. In copy-out mode, cpio copies files
into an archive. It reads a list of filenames, one per line, on the
standard input, and writes the archive onto the standard output. A
typical way to generate the list of filenames is with the find
command; you should give find the -depth option to minimize problems
with permissions on directories that are unwritable or not searchable.
In copy-in mode, cpio copies files out of an archive or lists the
archive contents. It reads the archive from the standard input. Any
non-option command line arguments are shell globbing patterns; only
files in the archive whose names match one or more of those patterns
are copied from the archive. Unlike in the shell, an initial `.' in a
filename does match a wildcard at the start of a pattern, and a `/' in
a filename can match wildcards. If no patterns are given, all files
are extracted.
In copy-pass mode, cpio copies files from one directory tree to
another, combining the copy-out and copy-in steps without actually
using an archive. It reads the list of files to copy from the
standard input; the directory into which it will copy them is given as
a non-option argument.
Cpio supports the following archive formats: binary, old ASCII, new
ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1 tar.
The binary format is obsolete because it encodes information about the
files in a way that is not portable between different machine
architectures. The old ASCII format is portable between different
machine architectures, but should not be used on file systems with
more than 65536 i-nodes. The new ASCII format is portable between
different machine architectures and can be used on any size file
system, but is not supported by all versions of cpio; currently, it is
only supported by GNU and Unix System V R4. The crc format is like
the new ASCII format, but also contains a checksum for each file which
cpio calculates when creating an archive and verifies when the file is
extracted from the archive. The HPUX formats are provided for
compatibility with HPUX's cpio which stores device files differently.
The tar format is provided for compatability with the tar program. It
can not be used to archive files with names longer than 100
characters, and can not be used to archive "special" (block or
character devices) files. The POSIX.1 tar format can not be used to
archive files with names longer than 255 characters (less unless they
have a "/" in just the right place).
By default, cpio creates binary format archives, for compatibility
with older cpio programs. When extracting from archives, cpio
automatically recognizes which kind of archive it is reading and can
read archives created on machines with a different byte-order.
Some of the options to cpio apply only to certain operating modes; see
the SYNOPSIS section for a list of which options are allowed in which
modes.
This archive is the original FSF source distribution before any
Amiga specific changes.
