NAME

cachefspack - pack files and file systems in the cache  

SYNOPSIS

cachefspack [-h] [-i | -p | -u] [-f packing-list] [-U cache-directory] [file...]  

DESCRIPTION

The cachefspack utility is used to set up and maintain files in the cache. This utility affords greater control over the cache, ensuring that the specified files are in the cache whenever possible.

cachefspack does not pack files when the backfileystem type for the cachefs mount is NFSv4. This is because only pass-through support is available for cachefs with NFSv4.  

OPTIONS

The following options are supported:

-f packing-list Specify a file containing a list of files and directories to be packed. Options within subdirectories and files can also be specified. The format and rules governing packing-list are described on the packingrules(4) manual page. Directories are packed recursively. Symlinks that match a regular expression on a LIST command are followed. Symlinks encountered while recursively processing directories are not followed.

-h Help. Print a brief summary of all the options.

-i View information about the packed files.

-p Pack the file or files specified by file. This is the default behavior.

-u Unpack the file or files specified by file.

-U cache-directory Unpack all files in the specified cache directory.

 

OPERANDS

The following operands are supported:

file A path name of a file to be packed or unpacked.

 

USAGE

See largefile(5) for the description of the behavior of cachefspack when encountering files greater than or equal to 2 Gbyte ( 2 **31
 bytes).  

EXAMPLES

Example 1: Packing a File in the Cache

The following example packs the file projects in the cache:

% cachefspack -p projects

Example 2: Packint Files in the Cache

The following example packs the files projects, updates, and master_plan in the cache:

% cachefspack -p projects updates master_plan

Example 3: Unpacking a File From the Cache

The following example unpacks the file projects from the cache:

% cachefspack -u projects

Example 4: Unpacking Files From the Cache

The following example unpacks the files projects, updates, and master_plan from the cache:

% cachefspack -u projects updates master_plan

Example 5: Unpacking All Files From in a Cache Directory

The following example unpacks all files in the cache directory cache1:

% cachefspack -U /cache/cache1

Example 6: Using a Packing List

The following example illustrates the use of a packing list to specify files to be packed in the cache.

The contents of lists.pkg are as follows:

IGNORE SCCS BASE /src/junk LIST *.c LIST *.h

The following command packs all files in the /src/junk directory which have .c and .h extensions, and do contain the string SCCS in the file's path name:

% cachefspack -f lists.pkg
