Hi,

Thnx for the reply.

I tried pax with following paramters:

Code:
# pax -r -s ',^/home/compdir/home2/Rev83/data/PL/01,/home/temp,' -f /dev/rct0 "*PL*"
UX:pax: WARNING: /dev/rct0 : This doesn't look like a tar archive
UX:pax: WARNING: /dev/rct0 : Skipping to next file...
UX:pax: ERROR: *PL* not found in archive

and I tried:

Code:
#cpio -icvd "home/compdir/home2/Rev83/data/PL/01/*.*" < /dev/rct0

It took long time but nothing happend.

Pls advise.

Rgrds,
Tayyab

ARCHIVE_WRITE_FORMAT(3) 				   BSD Library Functions Manual 				   ARCHIVE_WRITE_FORMAT(3)

NAME
archive_write_set_format_cpio, archive_write_set_format_pax, archive_write_set_format_pax_restricted, archive_write_set_format_shar, archive_write_set_format_shar_dump, archive_write_set_format_ustar -- functions for creating archives LIBRARY
Streaming Archive Library (libarchive, -larchive) SYNOPSIS
#include <archive.h> int archive_write_set_format_cpio(struct archive *); int archive_write_set_format_pax(struct archive *); int archive_write_set_format_pax_restricted(struct archive *); int archive_write_set_format_shar(struct archive *); int archive_write_set_format_shar_dump(struct archive *); int archive_write_set_format_ustar(struct archive *); DESCRIPTION
These functions set the format that will be used for the archive. The library can write POSIX octet-oriented cpio format archives, POSIX-standard ``pax interchange'' format archives, traditional ``shar'' ar- chives, enhanced ``dump'' shar archives that store a variety of file attributes and handle binary files, and POSIX-standard ``ustar'' ar- chives. The pax interchange format is a backwards-compatible tar format that adds key/value attributes to each entry and supports arbitrary filenames, linknames, uids, sizes, etc. ``Restricted pax interchange format'' is the library default; this is the same as pax format, but suppresses the pax extended header for most normal files. In most cases, this will result in ordinary ustar archives. RETURN VALUES
These functions return ARCHIVE_OK on success, or ARCHIVE_FATAL. ERRORS
Detailed error codes and textual descriptions are available from the archive_errno() and archive_error_string() functions. SEE ALSO
