Portable Archive Exchange program. When
members of the POSIX 1003.2 working group could not standardize on
invented this program. (See also
tar.) Note that until native drivers for tape
drives exist for Mac OS X,
pax cannot write to
tape. Note also that
pax does not preserve
resource forks or HFS metadata when copying files that contain them.
pax operates in four modes, depending on the
-r and no
-w. List the
contents of a
pax archive. Optionally, restrict
the output to filenames and/or directories that match a given
-r only. Extract files from a
pax archive. Intermediate directories are created
-w only. Archive files to a new or existing
pax archive. The archive is written to standard
output; it may be redirected to an appropriate tape device if needed
-w. Copy a directory
tree from one location to another, analogous to
Here are the options available in the four modes:
None: c d f n s v U G T
-r:c d f i k n o p s u v D Y Z E U G T
-w:a b d f i o s t u v x H L P X U G B T
-rw:d i k l n p s t u v D H L P X Y Z U G T
Append files to the archive. This may not work on some tape devices.
Use size as the blocksize, in bytes, of blocks to be written to the archive.
Complement. Match all file or archive members that do not match the patterns.
