cpio arşiv dosyaları

Archival

If you wanted to archive an entire directory tree, the find command can provide the file list to cpio:

% find . -depth -print  cpio -ov > tree.cpio

Copy
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.

% find . -depth -print0 cpio --null -pvd new-dir

Extraction

To extract files from a cpio archive, pass the archive to cpio as its standard input.

Warning: This will overwrite without prompting.

% cpio -id < cpiofile

The -i flag indicates that cpio is reading in the archive to extract files, and the -d flag tells cpio to construct directories as necessary. You can also use the -v flag to have file names listed as files are extracted.

Any non-option command line arguments are shell-like globbing-patterns; only files in the archive whose names match one or more of those patterns are copied from the archive. The following example extracts etc/fstab from the archive (the format of the archive contents should be verified with `cpio -l` first to verify how path is stored) :

% cpio -id etc/fstab < cpiofile
