# systune(8)

Kernel tuning through the /proc filesystem.

## NAME

systune - Kernel tuning through the /proc filesystem.

## SYNOPSIS

**systune** \[ **-c, --config** *configfile* \] \[ **-h, --help** \] \[ **-v, --verbose** \]

## 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.

## 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.

## SEE ALSO

[**systunedump**(8)](/systunedump/8.md).
