systunedump - Dumps /proc files for kernel tuning.

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

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) 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

-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.

/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.
