A .tar file keeps related files together and facilitates the transfer of multiple files.
A .tar file is a series of separate files, typically not compressed, added together
into a single file by a UNIX TAR program. The resulting file is known as a tarball,
which is similar to a ZIP file but without the compression. The files in a .tar file
must be extracted before they can be used.
To untar a single file with a .tar extension in the disk0: file system, use the untar
command in Exec mode. Use this command to untar the sample scripts file. You
can also use this command to unzip a back-up licenses if a license becomes
corrupted or lost. Before you can use the untar command, the filename must end
with a .tar extension.
The copy licenses disk0: command creates backup .tar license files on the ACE.
If a license becomes corrupted or lost, or you accidently remove the license on the
ACE, you can untar the license and reinstall it. See the
section.
The syntax for the command is:
untar disk0:[path/]filename
The filename argument identifies the name of the .tar file in the disk0: file system.
The filename must end with a .tar extension. You can optionally provide a path to
the .tar file if it exists in another directory in the disk0: file system.
For example, to untar a series of license files in the mylicense.tar file in the disk0:
file system, enter:
host1/Admin# untar disk0:mylicenses.tar
To create a directory in the disk0: file system of Flash memory, use the mkdir
disk0: command in Exec mode. The syntax for this command is:
mkdir disk0:[path/]directory
