NAMEneedrestart - needrestart
DESCRIPTIONneedrestart checks which daemons need to be restarted after library upgrades.
- needrestart [-(v|q)] [-n] [-c <cfg>] [-r <mode>] [-f <fe>] [-u <ui>] [-(b|p)] [-kl]
- be more verbose
- be quiet
- -m <mode>
- set level of technical details
- (e)asy mode
- (a)dvanced mode
- set default answer to 'no'
- -c <cfg>
- config filename
- -r <mode>
- set restart mode
- (l)ist only
- (i)nteractive restart
- (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.
- enable batch mode
- 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:
- check for obsolete kernel
- check for obsolete libraries
ENVIRONMENTThe following environment variables can be used to override the config file options. Command line parameters do always supersede them.
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:
- The debconf(7) frontend to use, can also set using the -f parameter.
- If set to a non-empty value the apt-get(8) hook will not run needrestart after installing or updating packages.
