Creating, Displaying, and Extracting tar Files
You can create a tar file and write files into it, list the files in a tar file, and extract the files from a tar
file as described in the next sections.

Creating a tar File

To create a tar file and write files into it, use this privileged EXEC command:
archive tar /create destination-url flash:/file-url
For destination-url, specify the destination URL alias for the local or network file system and the name
of the tar file to create. These options are supported:
•For the local Flash file system, the syntax is
flash:
•For the File Transfer Protocol (FTP), the syntax is
ftp:[[//username[:password]@location]/directory]/tar-filename.tar
•For the Remote Copy Protocol (RCP), the syntax is
rcp:[[//username@location]/directory]/tar-filename.tar
•For the Trivial File Transfer Protocol (TFTP), the syntax is
tftp:[[//location]/directory]/tar-filename.tar
The tar-filename.tar is the tar file to be created.
For flash:/file-url, specify the location on the local Flash file system from which the new tar file is
created. You can also specify an optional list of files or directories within the source directory to write
to the new tar file. If none are specified, all files and directories at this level are written to the newly
created tar file.
This example shows how to create a tar file. This command writes the contents of the new-configs
directory on the local Flash device to a file named saved.tar on the TFTP server at 172.20.10.30:
Switch# archive tar /create tftp:172.20.10.30/saved.tar flash:/new-configs

Displaying the Contents of a tar File

To display the contents of a tar file on the screen, use this privileged EXEC command:
archive tar /table source-url
For source-url, specify the source URL alias for the local or network file system. These options are
supported:
•For the local Flash file system, the syntax is
flash:
•For the File Transfer Protocol (FTP), the syntax is
ftp:[[//username[:password]@location]/directory]/tar-filename.tar
•For the Remote Copy Protocol (RCP), the syntax is
rcp:[[//username@location]/directory]/tar-filename.tar
•For the Trivial File Transfer Protocol (TFTP), the syntax is
tftp:[[//location]/directory]/tar-filename.tar
The tar-filename.tar is the tar file to display.
