UDEV.CONF(5)							     udev.conf							      UDEV.CONF(5)

NAME
udev.conf - Configuration for device event managing daemon SYNOPSIS
/etc/udev/udev.conf DESCRIPTION
systemd-udevd(8) expects its main configuration file at /etc/udev/udev.conf. It consists of a set of variables allowing the user to override default udev values. All empty lines or lines beginning with '#' are ignored. The following variables can be set: udev_log The log level. Valid values are the numerical syslog priorities or their textual representations: err, info and debug. In addition, systemd-udevd can be configured by command line options and the kernel command line (see systemd-udevd(8)). SEE ALSO

NAME
systemd-udevd.service, systemd-udevd-control.socket, systemd-udevd-kernel.socket, systemd-udevd - Device event managing daemon SYNOPSIS
systemd-udevd.service systemd-udevd-control.socket systemd-udevd-kernel.socket /usr/lib/systemd/systemd-udevd [--daemon] [--debug] [--children-max=] [--exec-delay=] [--resolve-names=early|late|never] [--version] [--help] DESCRIPTION
systemd-udevd listens to kernel uevents. For every event, systemd-udevd executes matching instructions specified in udev rules. See udev(7). The behavior of the running daemon can be changed with udevadm control. OPTIONS
--daemon Detach and run in the background. --debug Print debug messages to stderr. --children-max= Limit the number of events executed in parallel. --exec-delay= Delay the execution of RUN instruction by the given number of seconds. This option might be useful when debugging system crashes during coldplug caused by loading non-working kernel modules. --resolve-names= Specify when systemd-udevd should resolve names of users and groups. When set to early (the default) names will be resolved when the rules are parsed. When set to late names will be resolved for every event. When set to never names will never be resolved and all devices will be owned by root. --version Print version number. --help Print help text. ENVIRONMENT
$UDEV_LOG= Set the logging priority. KERNEL COMMAND LINE
Parameters starting with "rd." will be read when systemd-udevd is used in an initrd. udev.log-priority=, rd.udev.log-priority= Set the logging priority. udev.children-max=, rd.udev.children-max= Limit the number of events executed in parallel. udev.exec-delay=, rd.udev.exec-delay= Delay the execution of RUN instruction by the given number of seconds. This option might be useful when debugging system crashes during coldplug caused by loading non-working kernel modules. net.ifnames= Network interfaces are renamed to give them predictable names when possible. It is enabled by default, specifying 0 disables it. CONFIGURATION FILE
udev expects its main configuration file at /etc/udev/udev.conf. It consists of a set of variables allowing the user to override default udev values. All empty lines or lines beginning with '#' are ignored. The following variables can be set: udev_log The logging priority. Valid values are the numerical syslog priorities or their textual representations: err, info and debug. SEE ALSO

Shopt -s histappend

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file. # When the shell exits, append to the history file instead of overwriting it shopt -s histappend (3 Replies)
