Example--Creating a Packing List

The following example shows the contents of a packing list file.

BASE /home/ignatz
LIST plans
LIST docs
IGNORE *.ps

• The path identified with the BASE statement is the directory where you have items you want to pack.

• The two LIST statements identify specific files within that directory to pack.

• The IGNORE statement identifies the file type of .ps, which you do not want to pack.

How to Pack Files in the Cache With a Packing List

Pack files in the packing list by using the cachefspack -f command, as follows:

$ cachefspack -f packing-list

Example--Packing Files in the Cache With a Packing List

This example uses the list.pkg file as the packing list for the cachefspack command.

$ cachefspack -f list.pkg

Unpacking Files or Packing Lists From the Cache

You might need to remove, or unpack, a file from the cache. Perhaps you have some files or directories that have a higher priority than others, so you need to unpack the less critical files. For example, you finished up a project and have archived the files that are associated with that project. You are now working on a new project, and therefore, a new set of files.

How to Unpack Files or Packing Lists From the Cache

Unpack files or packing lists from the cache by using the -u or -U option of the cachefspack command.

$ cachefspack -u filename | -U cache-directory

For more information about the cachefspack command, see the man page.

Examples--Unpacking Files or Packing Lists From the Cache

The following example shows the file /data/abc/bin/big being unpacked from the cache.

$ cachefspack -u /data/abc/bin/big

The following example shows several files being unpacked from the cache.

$ cd /data/abc/bin/big
$ cachefspack -u big small medium

The following example shows how to unpack a packing list, which is a file that contains the path to a directory of files, as follows:

$ cachefspack -uf list.pkg

The following example uses the -U option to specify that all files in a cache directory being unpacked.

$ cachefspack -U /local/mycache

You cannot unpack a cache that does not have at least one file system mounted. With the -U option, if you specify a cache that does not contain mounted file systems, you see output similar to the following:

$ cachefspack -U /local/mycache
cachefspack: Could not unpack cache /local/mycache, no mounted
filesystems in the cache.
