cachefspack(1M) System Administration Commands cachefspack(1M)NAMEcachefspack - pack files and file systems in the cache
SYNOPSIScachefspack [-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 subdi‐
rectories 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 com‐
mand are followed. Symlinks encountered while
recursively processing directories are not fol‐
lowed.
-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 direc‐
tory.
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 mas‐
ter_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 mas‐
ter_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
EXIT STATUS
0 Successful completion.
>0 An error occurred.
