.TH SYSTUNEDUMP 8 "20 Apr 1999" "Debian Project" "Debian GNU/Linux"

.SH NAME
systunedump \- Dumps /proc files for kernel tuning.

.SH SYNOPSIS
.B systunedump
[
.BI \-c, \-\-config " configfile
] [
.BI "\-h, \-\-help"
] [
.BI "-p, \-\-path " dumppath
] [
.BI "-v, \-\-verbose"
]

.SH DESCRIPTION
This program dumps elements of the /proc filesystem to standard output
in a format which, if redirected to a file, can be used by the 
.B systune(8)
utility.

Common usage:

.BI "systunedump > " /etc/systune.conf

.BI "systunedump \-\-config " /etc/systune.kernel20.dump " > "
.BI "/etc/systune.kernel20.conf"

.BI "systunedump \-\-config " /dev/null " \-\-path " /proc/sys/vm " > "
.BI "/etc/systune.conf"


.SH OPTIONS
.TP
.BI "\-c, \-\-config " configfile
Specify an alternative configuration file.  The default is
.I /etc/systune.dump
.
.TP
.BI "\-h, \-\-help"
Print a short explanation of the command syntax.
.TP
.BI "\-p, \-\-path " dumppath
Add the specified path to any items already listed in the configuration
file.  Items in the path must be separated by whitespace.  All items in the
path must begin 
.BR /proc/sys/ .
.TP
.BI "\-v, \-\-verbose"
Verbose mode: allow non-existent items in the path and configuration file
to produce errors to standard error.  Without this option, erroneous paths
are discarded silently.

.SH FILES
.TP 
.I /etc/systune.dump
A file containing a list of paths to dump.  Each pathname must begin with
.BR /proc/sys/ .
Comments, introduced by #, can be included; the whole line from the comment
character onwards is discarded, together with any whitespace immediately
preceding it. 
.PP
The configuration file can be a file, such as
.IR /etc/systune.conf ,
that contains previously dumped data; the definition part of each line, after
and including the colon, is discarded.
