pax(1) MPE/iX Shell and Utilities pax(1)
In write mode, –u checks to see if the file being added has the same name as a file
already in the archive. If so, and if the file being added is newer than the one in the
archive, pax leaves the old file in the archive and appends the new one at the end. In
this case, –u automatically implies –a, which means that pax adds new files to the
end of the archive.
–V volpat
provides automatic multi-volume support. pax writes output to files the names of
which are formatted using volpat. It replaces any occurrence of # in volpat with the
current volume number. When you invoke pax with this option, it asks for the first
number in the archive set, and waits for you to type the number and a carriage return
before proceeding with the operation. pax issues the same sort of message when a
write error or read error occurs on the archive; the reasoning is that this kind of error
means that pax has reached the end of the volume and is to go on to a new one. An
interrupt at this point terminates pax.
–v in list mode, displays a verbose table of contents; this verbose format shows informa-
tion about the components in the same format used by the ls(1) command with the
–l option. In other modes, this option lists path names on the standard error stream
just before beginning to process the files/directories, but after any –i or –s options
have had their effect.
–w writes files to the standard output in the specified archive format.
–X only writes out those files which are on the same device as their parent directory.
–x format
specifies a format for an output archive. The format argument may be:
cpio standing for the
ASCII format used by the cpio command, described in
cpio(1) and cpio(2).
cpiob standing for the binary format used by cpio.
tar standing for the old format of tar files; see tar(1) and tar(2).
ustar standing for the (new)
USTAR format used by the tar command.
The default format is ustar.
–z performs Lempel-Ziv compression. The number of bits of compression used for
input and output is system defined.
Output
In the output, the notation
pathname == linkname
