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)
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.
