checkrestart - check which processes need to be restarted after an upgrade SYNOPSIS
checkrestart [ -hvpa ] [ -b blacklist_file ] [ -i package_name ] DESCRIPTION
The checkrestart program tries to determine if there are processes in the system that need to be restarted after a system upgrade. This is necessary since an upgrade will usually bring new system libraries and running processes will be still using the old versions of the libraries. In stable Debian GNU/Linux systems this is typically needed to eliminate a system exposure to a vulnerability which might have been fixed by upgrading a library which that process makes use of. Consequently, checkrestart is sometimes used as an audit tool to find outdated versions of libraries in use, particularly after security upgrades. Administrators should not, however, rely on its output completely (see BUGS below). This script needs to run as root in order to obtain the information it needs for analysis. OPTIONS
-h,--help Show the program help and exit. -v,--verbose Generate detailed output. This output includes the list of all processes found using deleted files or descriptors as well as the deleted files and descriptors found. -p,--package Only process deleted files that belong to a package, ignoring deleted files which do not have an associated package in the package system. -a,--all Process all deleted files regardless of location. This makes the program analyse deleted files even if they would be discarded because they are located in locations, such as /tmp , which are known to produce false positives. It will take preceded if used simultaneously with the -p option. -b file,--blacklist=file Read a blacklist of regular expressions from file. Any files matching the patterns will be ignored. -i name,--ignore=name Ignore services that are associated to the package name provided in name. EXIT STATUS
The program will exit with error (1) if a non-root user tries to run it. Otherwise, it will always exit with error status 0. BUGS
This program might fail if the output of the lsof utility changes since it depends on it to detect which deleted files are used by pro- cesses. It might also output some false positives depending on the processes' behaviour since it does not check yet if the (deleted) files in use are really libraries. If you find a false positive in checkrestart please provide the following information when submitting a bug report: -- The output of checkrestart using the -v (verbose) option. -- The output of running the following command as root: lsof | egrep 'delete|DEL|path inode' Checkrestart is also sensitive to the kernel version in use. And might fail to work with newer (or older) versions. A rewrite to make it less dependent on lsof could improve this, however. SEE ALSO

gdiffmk - mark differences between groff/nroff/troff files SYNOPSIS
gdiffmk [ -aaddmark ] [ -cchangemark ] [ -ddeletemark ] [ -D [ -B ] [ -Mmark1 mark2 ] ] [ -xdiffcmd ] [ -- ] [ --help ] [ --version ] file1 file2 [ output ] DESCRIPTION
gdiffmk compares two groff(1), nroff(1), or troff(1) documents, file1 and file2, and creates an output which is file2 with added `margin character' (.mc) commands that indicate the differences. If the output filename is present, the output is written there. If it is - or absent the output is written to the standard output. If the file1 or file2 argument is - the standard input is read for that input. Clearly both cannot be -. Note that the output is not necessarily compatible with all macro packages and all preprocessors. See the BUGS section below. OPTIONS
-aaddmark Use the addmark for source lines not in file1 but present in file2. Default: +. -B By default, the deleted texts marked by the -D option end with an added troff break command, .br, to ensure that the deletions are marked properly. This is the only way to guarantee that deletions and small changes get flagged. This option directs the program not to insert these breaks; it makes no sense to use it without -D. -cchangemark Use the changemark for changed source lines. Default: |. -ddeletemark Use the deletemark for deleted source lines. Default: *. -D Show the deleted portions from changed and deleted text. Default delimiting marks: [[ .... ]]. -Mmark1 mark2 Change the delimiting marks for the -D option. It makes no sense to use this option without -D. -xdiffcmd Use the diffcmd command to perform the comparison of file1 and file2. In particular, diffcmd should accept the GNU diff -Dname option. Default: diff(1). -- All the following arguments are treated as file names, even if they begin with -. --help Print a usage message on standard error output and exit. --version Print version information on the standard output and exit. BUGS
The output is not necessarily compatible with all macro packages and all preprocessors. A workaround that is often successful against pre- processor problems is to run gdiffmk on the output of all the preprocessors instead of the input source. gdiffmk relies on the -Dname option of GNU diff(1) to make a merged `#ifdef' output format. It hasn't been tested whether other versions of diff(1) do support this option. See also the -xdiffcmd option. Report bugs to bug-groff@gnu.org. Include a complete, self-contained example that will allow the bug to be reproduced, and say which ver- sion of gdiffmk you are using. AUTHORS
