NAME
paxcpio — copy file archives in and out
SYNOPSIS
paxcpio -o [-0AaBcJjLVvZz] [-C bytes] [-F archive] [-H format] [-M flag] [-O archive] <
name-list [> archive]
paxcpio -i [-06BbcdfJjmrSstuVvZz] [-C bytes] [-E file] [-F archive] [-H format] [-I archive]
[-M flag] [pattern ...] [< archive]
paxcpio -p [-0adLlmuVv] destination-directory < name-list
DESCRIPTION
The paxcpio command copies files to and from a cpio archive.
The options are as follows:
-0 Use the NUL (‘\0’) character as a pathname terminator, instead of newline (‘\n’).
This applies only to the pathnames read from standard input in the write and copy
modes, and to the pathnames written to standard output in list mode. This option is
expected to be used in concert with the -print0 function in find(1) or the -0 flag
in xargs(1).
-o Create an archive. Reads the list of files to store in the archive from standard
input, and writes the archive on standard output.
-A Append to the specified archive.
-a Reset the access times on files that have been copied to the archive.
-B Set block size of output to 5120 bytes.
-C bytes
Set the block size of output to bytes.
-c Use ASCII format for cpio header for portability.
-F archive
Use the specified file as the input for the archive.
-H format
Write the archive in the specified format. Recognised formats are:
ar Unix Archiver.
bcpio Old binary cpio format. Selected by -6.
cpio Old octal character cpio format. Selected by -c.
sv4cpio SVR4 hex cpio format.
sv4crc SVR4 hex cpio format with checksums. This is the default format
for creating new archives.
tar Old tar format.
ustar POSIX ustar format.
bin These four formats...
crc ...are supported...
newc ...for backwards...
odc ...compatibility only.
-J Use the xz utility to compress the archive.
-j Use the bzip2 utility to compress the archive.
-L Follow symbolic links.
-M flag
Configure the archive normaliser. flag is either a numeric value compatible
to strtonum(3) which is directly stored in the flags word, or one of the
following values, optionally prefixed with “no-” to turn them off:
inodes 0x0001: Serialise inodes, zero device info.
(cpio, sv4cpio, sv4crc)
links 0x0002: Store content of hard links only once.
(cpio, sv4cpio, sv4crc)
mtime 0x0004: Zero out the file modification time.
(ar, cpio, sv4cpio, sv4crc, ustar)
uidgid 0x0008: Set owner to 0:0 (root:wheel).
(ar, cpio, sv4cpio, sv4crc, ustar)
verb 0x0010: Debug this option.
debug 0x0020: Debug file header storage.
lncp 0x0040: Extract hard links by copy if link fails.
numid 0x0080: Use only numeric uid and gid values.
(ustar)
gslash 0x0100: Append a slash after directory names.
(ustar)
set 0x0003: Keep ownership and mtime intact.
dist 0x008B: Clean everything except mtime.
norm 0x008F: Clean everything.
root 0x0089: Clean owner and device information.
When creating an archive and verbosely listing output, these normalisation
operations are not reflected in the output, because they are made only after
the output has been shown.
This option is only implemented for the ar, cpio, sv4cpio, sv4crc, and ustar
file format writing routines.
-O archive
Use the specified file name as the archive to write to.
-V Print a dot (‘.’) for each file written to the archive.
-v Be verbose about operations. List filenames as they are written to the
archive.
-Z Use the compress(1) utility to compress the archive.
-z Use the gzip(1) utility to compress the archive.
-i Restore files from an archive. Reads the archive file from standard input and
extracts files matching the patterns that were specified on the command line.
-6 Process old-style cpio format archives.
-B Set the block size of the archive being read to 5120 bytes.
-b Do byte and word swapping after reading in data from the archive, for
restoring archives created on systems with a different byte order.
-C bytes
Read archive written with a block size of bytes.
-c Expect the archive headers to be in ASCII format.
-d Create any intermediate directories as needed during restore.
-E file
Read list of file name patterns to extract or list from file.
-F archive, -I archive
Use the specified file as the input for the archive.
-f Restore all files except those matching the patterns given on the command
line.
-H format
Read an archive of the specified format. Recognised formats are:
ar Unix Archiver.
bcpio Old binary cpio format.
cpio Old octal character cpio format.
sv4cpio SVR4 hex cpio format.
sv4crc SVR4 hex cpio format with checksums.
tar Old tar format.
ustar POSIX ustar format.
bin These four formats...
crc ...are supported...
newc ...for backwards...
odc ...compatibility only.
-J Use the xz utility to decompress the archive.
-j Use the bzip2 utility to decompress the archive.
-m Restore modification times on files.
-r Rename restored files interactively.
-S Swap words after reading data from the archive.
-s Swap bytes after reading data from the archive.
-t Only list the contents of the archive, no files or directories will be
created.
-u Overwrite files even when the file in the archive is older than the one that
will be overwritten.
-V Print a dot (‘.’) for each file read from the archive.
-v Be verbose about operations. List filenames as they are copied in from the
archive.
-Z Use the compress(1) utility to decompress the archive.
-z Use the gzip(1) utility to decompress the archive.
-p Copy files from one location to another in a single pass. The list of files to copy
are read from standard input and written out to a directory relative to the
specified directory argument.
-a Reset the access times on files that have been copied.
-d Create any intermediate directories as needed to write the files at the new
location.
-L Follow symbolic links.
-l When possible, link files rather than creating an extra copy.
-m Restore modification times on files.
-u Overwrite files even when the original file being copied is older than the
one that will be overwritten.
-V Print a dot (‘.’) for each file copied.
-v Be verbose about operations. List filenames as they are copied.
ENVIRONMENT
TMPDIR Path in which to store temporary files.
EXIT STATUS
The paxcpio utility exits with one of the following values:
0 All files were processed successfully.
1 An error occurred.
DIAGNOSTICS
Whenever paxcpio cannot create a file or a link when extracting an archive or cannot find a
file while writing an archive, or cannot preserve the user ID, group ID, file mode, or
access and modification times when the -p option is specified, a diagnostic message is
written to standard error and a non-zero exit value will be returned, but processing will
continue. In the case where paxcpio cannot create a link to a file, unless -M lncp is
given, paxcpio will not create a second copy of the file.
If the extraction of a file from an archive is prematurely terminated by a signal or error,
paxcpio may have only partially extracted the file the user wanted. Additionally, the file
modes of extracted files and directories may have incorrect file bits, and the modification
and access times may be wrong.
If the creation of an archive is prematurely terminated by a signal or error, paxcpio may
have only partially created the archive, which may violate the specific archive format
specification.
