# systunedump(8)

Dumps /proc files for kernel tuning.

## NAME

systunedump - Dumps /proc files for kernel tuning.

## SYNOPSIS

**systunedump** \[ **-c,***--config* **configfile** \] \[ **-h, --help** \] \[ **-p, --path** *dumppath* \] \[ **-v, --verbose** \]

## 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  **[systune(8)](/systune/8.md)** utility.

Common usage:

**systunedump \>** */etc/systune.conf*

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

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

## OPTIONS

- **-c, --config** *configfile*

  Specify an alternative configuration file.  The default is */etc/systune.dump*

- **-h, --help**

  Print a short explanation of the command syntax.

- **-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  **/proc/sys/**.

- **-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.

## FILES

- */etc/systune.dump*

  A file containing a list of paths to dump.  Each pathname must begin with **/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.

The configuration file can be a file, such as */etc/systune.conf*, that contains previously dumped data; the definition part of each line, after and including the colon, is discarded.
