pax - read and write file archives and copy directory hierarchies. A POSIX File System Archiver. It supports the two most common forms of standard Unix archive (backup) files: cpio and tar.
Examples
- Copy the contents of the current directory to the device
/dev/rst0:
pax -w -f /dev/rst0 .
- Give the verbose table of contents for an archive stored in
filename:
pax -v -f filename
- This sequence of commands will copy the entire
olddirdirectory hierarchy tonewdir:
mkdir newdir cd olddir pax -rw . newdir
- Read the archive
a.paxwith all files rooted in/usrinto the archive extracted relative to the current directory:
pax -r -s ',^//*usr//*,,' -f a.pax
- Can be used to interactively select the files to copy from the current directory to
dest_dir:
pax -rw -i . dest_dir
- Extract all files from the archive
a.paxwhich are owned by root with group bin and preserve all file permissions:
pax -r -pe -U root -G bin -f a.pax
- Update (and list) only those files in the destination directory
/backupwhich are older (less recent inode change or file modification times) than files with the same name found in the source file tree home:
pax -r -w -v -Y -Z home /backup
