# NAME

     checkrestart - help to find processes that need restarting after upgrade

# SYNOPSIS

     checkrestart [-v] [-M core] [-N system] [-W swap]

# DESCRIPTION

     checkrestart is a program designed to help to find processes that need

     restarting after upgrade.

     checkrestart walks through the entire file table of the system, searching

     for processes with a VTEXT node detached from the filesystem.

     By default, checkrestart will output the pid and executable name of these

     running processes.

     The options are as follows:

     -v      Verbose mode.  checkrestart will additionally output the inode

             and mount point of the unlinked node.

     -M core

             Extract values associated with the name list from the specified

             core instead of the running kernel.

     -N system

             Extract the name list from the specified system instead of the

             running kernel.

     -W swap

             When not using the running kernel, extract swap information from

             the specified file.

     The typical use case is:

     o   start a long lived program.

     o   later, upgrade your packages via pkg_add -u.

     o   if the program is updated on disk, the running program is still the

         previous one (without security fixes for example).

     o   checkrestart will tell you which processes belong to this category.

# SEE ALSO

     fstat(1)

# HISTORY

     The name checkrestart comes from a similar tool from Debian that relies

     on lsof(1) for achieving the same purpose.

# AUTHORS

     checkrestart was written by Sebastien Marie .

# CAVEATS

     Only VTEXT nodes are reported by checkrestart.  Some programs using old

     libraries aren't reported due to lack of kernel support.
