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

.SH NAME
systune \- Kernel tuning through the /proc filesystem.

.SH SYNOPSIS
.B systune
[
.BI "\-c, \-\-config " configfile
] [
.BI "\-h, \-\-help"
] [
.BI "\-v, \-\-verbose"
]

.SH DESCRIPTION
This program writes kernel parameters, previously saved in a configuration
file, to the /proc filesystem.  This enables kernel performance to be
adjusted without recompiling the kernel.

.SH OPTIONS
.TP
.BI "\-c, \-\-config " configfile
Specify an alternative config file.  The default is
.I /etc/systune.conf
.
.TP
.BI "\-h, \-\-help"
Print a short explanation of syntax to standard output.
.TP
.BI "-v, \-\-verbose"
Verbose mode: cause non-existent paths in the configuration to generate
error output to standard error.  Without this option, erroneous paths are
discarded silently.

.SH CONFIGURATION FILE FORMAT
Each definition takes a single line, in the form 
.IR path : definition ,
where 
.IR path
must begin with
.BR /proc/sys/ .
Paths beginning with any other sequence are silently ignored.
.PP
Comments are introduced by the character #.  The whole line from
the # character onwards is discarded, together with any whitespace
immediately preceding it.
.PP
Blank lines are ignored.

.SH FILES
.TP 
.I /etc/systune.conf
A file with saved kernel parameters. It is possible to generate this file
with the
.B systunedump (8)
command.

.SH SEE ALSO
.BR systunedump (8).
