## How to use it
You want to find out which running processes are effected of a upgrade of "libssl0.9.8" and "libxcomposite".
Whatsup outputs a list of packages which are using files of the the given packages in any nested dependency by looking in
the /proc-filesystem (/proc/$pid/maps)
The tool is also capable to list all init-scripts of the resulting packages.

NAME
whatsup - program to analyze package dependencies of running processes
SYNOPSIS
whatsup {-f | -h | -p pid... | -P pkg... | -r pkg... | -e file... } [-a | -d | -i ]
DESCRIPTION
This manual page documents briefly the whatsup command.
This tool provides information about package and file dependencies of currently running
processes. Information about the files which are currently associated with a certain proâ
cess is provided by ia file in the proc-filesystem. Each line in /proc/$pid/maps repreâ
sents a mapped region of the process. An entry in /proc/$pid/maps looks like this:
8048000-08051000 r-xp 00000000 fe:08 76910 /sbin/init
08051000-08052000 rwxp 00008000 fe:08 76910 /sbin/init
08052000-08073000 rwxp 08052000 00:00 0 [heap]
b7d4a000-b7d4b000 rwxp b7d4a000 00:00 0
b7d4b000-b7d4d000 r-xp 00000000 fe:08 231672 /lib/tls/i686/cmov/libdl-2.5.so
b7d4d000-b7d4f000 rwxp 00001000 fe:08 231672 /lib/tls/i686/cmov/libdl-2.5.so
b7d4f000-b7e8a000 r-xp 00000000 fe:08 231662 /lib/tls/i686/cmov/libc-2.5.so
Especially on server systems this is useful after security- and bugfix-updates to find out
which processes have to be restarted. The whatsup tool is automatically called after every
apt-operation.
OPTIONS
A summary of options is included below :
-h Show summary of options.
-f Display all files which are in use by currently running processes. Every filename
is followed by a list of process ids which are using this file.
-p Resolve the names of the debian packages of the given proccess ids. This option
displays a list of the given pids, the package name and the name of the running
binary.
-P Display all process ids which use files which are part the given debian packages
-r Same as "-P", but also display the name of the debian-package the process-binary
belongs to.
-i Display names of init scripts contained in the resulted packages. This option can
be used with the "-r" switch.
-e Extract package names of given packagefiles - i.e. a package name like "fooâ
bar_2.86.ds1-38_i386.deb" is interpreted as "foobar". This option can be used
with the "-r" and "-P" switch.
-a This option can be used to pass package-names over stdin by apt-get - i.e. calls
over /etc/apt/apt.conf.d/99whatsup.
-d Debug mode
