       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.
