systune8

Usage

Overview

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.

Options

-c, --config configfile

Specify an alternative config file. The default is /etc/systune.conf

-h, --help

Print a short explanation of syntax to standard output.

-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.

Configuration file format

Each definition takes a single line, in the form path:definition, where path must begin with /proc/sys/. Paths beginning with any other sequence are silently ignored.

Comments are introduced by the character #. The whole line from the # character onwards is discarded, together with any whitespace immediately preceding it.

Blank lines are ignored.

Files

/etc/systune.conf

A file with saved kernel parameters. It is possible to generate this file with the systunedump (8) command.
