NEEDRESTART

NAME

needrestart - needrestart

DESCRIPTION

needrestart checks which daemons need to be restarted after library upgrades.

USAGE

Usage:

needrestart [-(v|q)] [-n] [-c <cfg>] [-r <mode>] [-f <fe>] [-u <ui>] [-(b|p)] [-kl]

	-v		be more verbose
	-q		be quiet

-m <mode>

set level of technical details

	e		(e)asy mode
	a		(a)dvanced mode
	-n		set default answer to ’no’

-c <cfg>

config filename

-r <mode>

set restart mode

	l		(l)ist only
	i		(i)nteractive restart
	a		(a)utomatically restart

ATTENTION: If needrestart is configured to run in interactive mode but is run non-interactive (i.e. unattended-upgrades) it will fallback to list only mode.

	-b		enable batch mode
	-p		nagios plugin mode: makes output and exit codes nagios compatible

-f <fe>

override debconf(7) frontend, sets the DEBIAN_FRONTEND environment variable to <fe>

-t <seconds>

When checking running interpreter processes, allow process start times that are close to timestamps of files the interpreter uses, within this tolerance (default 2). The default value of 2 seconds is best for checks of Linux hosts, on which system limitations prevent more accurate measurements of process start times. Values higher than 0 should prevent false positives yet may in extreme cases cause false negatives; values higher than 2 should not be necessary.

-u <ui>

use preferred UI package (-u ? shows available packages)

By using one of the following options only the specified checks are performed:

	-k		check for obsolete kernel
	-l		check for obsolete libraries

ENVIRONMENT

The following environment variables can be used to override the config file options. Command line parameters do always supersede them.
NEEDRESTART_MODE

Change the configured restart mode (see also the -r parameter): (l)ist only, (i)nteractive or (a)utomatically

When used with apt-get(8) needrestart supports the following additional environment variables:
DEBIAN_FRONTEND

The debconf(7) frontend to use, can also set using the -f parameter.

NEEDRESTART_SUSPEND

If set to a non-empty value the apt-get(8) hook will not run needrestart after installing or updating packages.
