.TH CACHEFSPACK 1M "Mar 18, 2004"
.SH NAME
cachefspack \- pack files and file systems in the cache
.SH SYNOPSIS
.LP
.nf
\fBcachefspack\fR [\fB-h\fR] [\fB-i\fR | \fB-p\fR | \fB-u\fR] [\fB-f\fR \fIpacking-list\fR]
[\fB-U\fR \fIcache-directory\fR] [\fIfile\fR]...
.fi
.SH DESCRIPTION
.sp
.LP
The \fBcachefspack\fR 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.
.sp
.LP
\fBcachefspack\fR does not pack files when the backfileystem type for the
\fBcachefs\fR mount is NFSv4. This is because only pass-through support is
available for \fBcachefs\fR with NFSv4.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB\fR\fB-f\fR\fB \fR\fIpacking-list\fR\fR
.ad
.RS 22n
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 \fIpacking-list\fR are described on the \fBpackingrules\fR(4) manual
page. Directories are packed recursively. Symlinks that match a regular
expression on a \fBLIST\fR command are followed. Symlinks encountered while
recursively processing directories are not followed.
.RE
.sp
.ne 2
.na
\fB\fB-h\fR\fR
.ad
.RS 22n
Help. Print a brief summary of all the options.
.RE
.sp

.ad
.RS 22n
View information about the packed files.
.RE
.sp
.ne 2
.na
\fB\fB-p\fR\fR
.ad
.RS 22n
Pack the file or files specified by \fBfile\fR. This is the default behavior.
.RE
.sp
.ne 2

.RE
.sp
.ne 2
.na
\fB\fB\fR\fB-U\fR\fB \fR\fIcache-directory\fR\fR

.RE
.SH OPERANDS
.sp
.LP
The following operands are supported:
.sp
.ne 2
.na
\fB\fBfile\fR\fR
.ad
.RS 8n
A path name of a file to be packed or unpacked.
.RE
.SH USAGE
.sp
.LP
See \fBlargefile\fR(5) for the description of the behavior of \fBcachefspack\fR
when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
.SH EXAMPLES
.LP
\fBExample 1 \fRPacking a File in the Cache
.sp
.LP
The following example packs the file \fBprojects\fR in the cache:
.sp
.in +2
.nf
% cachefspack \fB-p\fR projects
.fi
.in -2
.sp
.LP
\fBExample 2 \fRPackint Files in the Cache
.sp
.LP
The following example packs the files \fBprojects\fR, \fBupdates\fR, and
\fBmaster_plan\fR in the cache:
.sp
.in +2
.nf
% cachefspack \fB-p\fR projects updates master_plan
.fi
.in -2
.sp
.LP
\fBExample 3 \fRUnpacking a File From the Cache
.sp
.LP
The following example unpacks the file \fBprojects\fR from the cache:
.sp
.in +2
.nf
% cachefspack \fB-u\fR projects
.fi
.in -2
.sp
.LP
\fBExample 4 \fRUnpacking Files From the Cache
.sp
.LP
The following example unpacks the files \fBprojects\fR, \fBupdates\fR, and
\fBmaster_plan\fR from the cache:
.sp
.in +2
.nf
% cachefspack \fB-u\fR projects updates master_plan
.fi
.in -2
.sp
.LP
\fBExample 5 \fRUnpacking All Files From in a Cache Directory
.sp
.LP
The following example unpacks all files in the cache directory \fBcache1\fR:
.sp
.in +2
.nf
% cachefspack \fB-U\fR /cache/cache1
.fi
.in -2
.sp
.LP
\fBExample 6 \fRUsing a Packing List
.sp
.LP
The following example illustrates the use of a packing list to specify files to
be packed in the cache.
.sp
.LP
The contents of \fBlists.pkg\fR are as follows:
.sp
.in +2
.nf
IGNORE SCCS BASE /src/junk LIST *.c LIST *.h
.fi
.in -2
.sp
.sp
.LP
The following command packs all files in the \fB/src/junk\fR directory which
have \fB\&.c\fR and \fB\&.h\fR extensions, and do contain the string SCCS in
the file's path name:
.sp
.in +2
.nf
% cachefspack \fB-f\fR lists.pkg
.fi
.in -2
.sp
.SH EXIT STATUS
.sp
.ne 2
