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.
