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|o)] [-x] [-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: don't restart anything and produce machine-readable output.
- -p
-
nagios plugin mode: makes output and exit codes nagios compatible
- -o
-
OpenMetrics output mode: output information that can be scraped by OpenMetrics-compatible services. Implies batch mode. By combining with any of `-l`, `-k` and `-w` you can decide whether the metrics will expose outdated libraries, kernel and microcode, respectively. Note that in order to list system-wide outdated libraries, needrestart needs to be run as root. When listing outdated libraries, a gauge-type metric exposes the number of running processes with such outdated libraries. When exposing kernel or microcode metrics, each one will expose a StateSet-type metric which indicates the current status. Kernel and microcode will also each expose an additional Info-type metric which informs of the versions of the current vs expected kernel or microcode.
- -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)
- -x
-
automatically exit the GUI when there is no process selected by default
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.
