-psmisc, version 19
-==================
-
-This package contains four little utilities that use the proc FS:
-
- fuser identifies processes using files or sockets (similar to Sun's
- or SGI's fuser)
- killall kills processes by name, e.g. killall -HUP named
- pidof like killall, buts lists PIDs instead of killing processes
- pstree shows the currently running processes as a tree
-
-They should work with most recent kernels. Man pages are included.

-.SH NAME
-fuser \- identify processes using files or sockets
-.SH SYNOPSIS
-.ad l
-.B fuser
-.RB [ \-a | \-s ]
-.RB [ \-n\ \fIspace ]
-.RB [ \-\fIsignal\fB ]
-.RB [ \-kimuv ]

-.B fuser
-.RB \-V
-.ad b
-.SH DESCRIPTION
-.B fuser
-displays the PIDs of processes using the specified files or file systems.
-In the default display mode, each file name is followed by a letter denoting
-the type of access:
-.RS
-.IP \fBc\fP
-current directory.
-.IP \fBe\fP
-executable being run.
-.IP \fBf\fP
-open file. \fBf\fP is omitted in default display mode.
-.IP \fBr\fP
-root directory.
-.IP \fBm\fP
-mmap'ed file or shared library.
-.RE
-.LP
-\fBfuser\fP returns a non-zero return code if none of the specified files
-is accessed or in case of a fatal error. If at least one access has been
-found, \fBfuser\fP returns zero.
-.PP
-In order to look up processes using TCP and UDP sockets, the corresponding
-name space has to be selected with the \fB-n\fP option. Then the socket(s) can
-be specified by the local and remote port, and the remote address. All fields
-are optional, but commas in front of missing fields must be present:
-
-.RB \fB[\fP\fIlcl_port\fP\fB][\fP,\fB[\fP\fIrmt_host\fP\fB][\fP,\fB[\fIrmt_port\fP\fB]]]
-
-Either symbolic or numeric values can be used for IP addresses and port
-numbers.
-.SH OPTIONS
-.IP \fB\-a\fP
-Show all files specified on the command line. By default, only files that are
-accessed by at least one process are shown.
-.IP \fB\-k\fP
-Kill processes accessing the file. Unless changed with \fB-\fP\fIsignal\fP,
-SIGKILL is sent. An \fBfuser\fP process never kills itself, but may kill
-other \fBfuser\fP processes. The effective user ID of the process executing
-\fBfuser\fP is set to its real user ID before attempting to kill.
-.IP \fB\-i\fP
-Ask the user for confirmation before killing a process. This option is
-silently ignored if \fB\-k\fP is not present too.
-.IP \fB\-l\fP
-List all known signal names.
-.IP \fB\-m\fP
-\fIname\fP specifies a file on a mounted file system or a block device that
-is mounted. All processes accessing files on that file system are listed.
-If a directory file is specified, it is automatically changed to
-\fIname\fP/. to use any file system that might be mounted on that
-directory.
-.IP \fB\-n\ \fIspace\fP
-Select a different name space. The name spaces \fBfile\fP (file names, the
-default), \fBudp\fP (local UDP ports), and \fBtcp\fP (local TCP ports) are
-supported. For ports, either the port number or the symbolic name can be
-specified. If there is no ambiguity, the shortcut notation
-\fIname\fB/\fIspace\fP (e.g. \fIname\fB/\fIproto\fP) can be used.
-.IP \fB\-s\fP
-Silent operation. \fB\-u\fP and \fB\-v\fP are ignored in this mode.
-\fB\-a\fP must not be used with \fB\-s\fP.
-.IP \fB\-\fIsignal\fP
-Use the specified signal instead of SIGKILL when killing processes. Signals
-can be specified either by name (e.g. \fB\-HUP\fP) or by number
-(e.g. \fB\-1\fP).
-.IP \fB\-u\fP
-Append the user name of the process owner to each PID.
-.IP \fB\-v\fP
-Verbose mode. Processes are shown in a \fBps\fP-like style. The fields PID,
-USER and COMMAND are similar to \fBps\fP. ACCESS shows how the process
-accesses the file. If the access is by the kernel (e.g. in the case of a
-mount point, a swap file, etc.), \fBkernel\fP is shown instead of the PID.
-.IP \fB\-V\fP
-Display version information.
-.IP \fB\-\fP
-Reset all options and set the signal back to SIGKILL.
-.SH FILES
-.nf
-/proc location of the proc file system
-.fi
-.SH EXAMPLES
-\fBfuser -km /home\fP kills all processes accessing the file system /home
-in any way.
-.LP
-\fBif fuser -s /dev/ttyS1; then :; else \fIsomething\fP; fi\fR invokes
-\fIsomething\fP if no other process is using /dev/ttyS1.
-.LP
-\fBfuser telnet/tcp\fP shows all processes at the (local) TELNET port.
-.SH RESTRICTIONS
-Processes accessing the same file or file system several times in the same way
-are only shown once.
-.PP
-If the same object is specified several times on the command line, some of
-those entries may be ignored.
-.PP
-\fBfuser\fP may only be able to gather partial information unless run with
-privileges. As a consequence, files opened by processes belonging to other
-users may not be listed and executables may be classified as mapped only.
-.PP
-Installing \fBfuser\fP SUID root will avoid problems associated with
-partial information, but may be undesirable for security and privacy
-reasons.
-.PP
-\fBudp\fP and \fBtcp\fP name spaces, and UNIX domain sockets can't be
-searched with kernels older than 1.3.78.
-.PP
-\fBudp\fP and \fBtcp\fP currently only work for IPv4.
-.PP
-Accesses by the kernel are only shown with the \fB-v\fP option.
-.PP
-The \fB-k\fP option only works on processes. If the user is the kernel,
-\fBfuser\fP will print an advice, but take no action beyond that.

-.TH KILLALL 1 "Sep 7, 1999" "Linux" "User Commands"
-.SH NAME
-killall \- kill processes by name
-.SH SYNOPSIS
-.ad l
-.B killall
-.RB [ \-egiqvw ]
-.RB [ \-\fIsignal\fB ]
-.I name ...
-.br
-.B killall
-.RB \-l
-.br
-.B killall
-.RB \-V
-.ad b
-.SH DESCRIPTION
-.B killall
-sends a signal to all processes running any of the specified commands. If no
-signal name is specified, SIGTERM is sent.
-.PP
-Signals can be specified either by name (e.g. \fB\-HUP\fP) or by number
-(e.g. \fB\-1\fP). Signal 0 (check if a process exists) can only be specified
-by number.
-.PP
-If the command name contains a slash (\fB/\fP), processes executing that
-particular file will be selected for killing, independent of their name.
-.PP
-\fBkillall\fP returns a non-zero return code if no process has been killed
-for any of the listed commands. If at least one process has been killed for
-each command, \fBkillall\fP returns zero.
-.PP
-A \fBkillall\fP process never kills itself (but may kill other \fBkillall\fP
-processes).
-.SH OPTIONS
-.IP \fB\-e\fP
-Require an exact match for very long names. If a command name is longer
-than 15 characters, the full name may be unavailable (i.e. it is swapped
-out). In this case, \fBkillall\fP will kill everything that matches within
-the first 15 characters. With \fB\-e\fP, such entries are skipped.
-\fBkillall\fP prints a message for each skipped entry
-if \fB\-v\fP is specified in addition to \fB\-e\fP,
-.IP \fB\-g\fP
-Kill the process group to which the process belongs. The kill signal is only
-sent once per group, even if multiple processes belonging to the same process
-group were found.
-.IP \fB\-i\fP
-Interactively ask for confirmation before killing.
-.IP \fB\-l\fP
-List all known signal names.
-.IP \fB\-q\fP
-Do not complain if no processes were killed.
-.IP \fB\-v\fP
-Report if the signal was successfully sent.
-.IP \fB\-V\fP
-Display version information.
-.IP \fB\-w\fP
-Wait for all killed processes to die. \fBkillall\fP checks once per second if
-any of the killed processes still exist and only returns if none are left.
-Note that \fBkillall\fP may wait forever if the signal was ignored, had no
-effect, or if the process stays in zombie state.
-.SH FILES
-.nf
-/proc location of the proc file system
-.fi
-.SH "KNOWN BUGS"
-Killing by file only works for executables that are kept open during
-execution, i.e. impure executables can't be killed this way.
-.PP
-Be warned that typing \fBkillall\fP \fIname\fP may not have the desired
-effect on non-Linux systems, especially when done by a privileged
-user.
-.PP
-\fBkillall \-w\fP doesn't detect if a process disappears and is replaced by
-a new process with the same PID between scans.

-.TH PIDOF 1 "May 6, 1998" "Linux" "User Commands"
-.SH NAME
-pidof \- finds processes by name and lists their PIDs
-.SH SYNOPSIS
-.ad l
-.B pidif
-.RB [ \-eg ]
-.I name ...
-.br
-.B pidof
-.RB \-V
-.ad b
-.SH DESCRIPTION
-.B pidof
-lists the PIDs of all processes running any of the specified commands.
-.PP
-If the command name contains a slash (\fB/\fP), processes executing that
-particular file will be selected, independent of their name.
-.PP
-\fBpidof\fP returns a non-zero return code if no process has been found
-for any of the listed commands. If at least one process has been found for
-each command, \fBpidof\fP returns zero.
-.SH OPTIONS
-.IP \fB\-e\fP
-Require an exact match for very long names. If a command name is longer
-than 15 characters, the full name may be unavailable (i.e. it is swapped
-out). In this case, \fBpidof\fP will list everything that matches within
-the first 15 characters. With \fB\-e\fP, such entries are silently skipped.
-.IP \fB\-g\fP
-Show process group IDs instead of process IDs. If multiple processes with
-the same process group ID were found, only the first process is shown.
-.IP \fB\-V\fP
-Display version information.
-.SH FILES
-.nf
-/proc location of the proc file system
-.fi
-.SH "KNOWN BUGS"
-Selection by file only works for executables that are kept open during
-execution, i.e. impure executables can't be selected this way.

-.TH PSTREE 1 "May 6, 1998" "Linux" "User Commands"
-.SH NAME
-pstree \- display a tree of processes
-.SH SYNOPSIS
-.ad l
-.B pstree
-.RB [ \-a ]
-.RB [ \-c ]
-.RB [ \-h | \-H \fIpid\fB ]
-.RB [ \-l ]
-.RB [ \-n ]
-.RB [ \-p ]
-.RB [ \-u ]
-.RB [ \-G | \-U ]
-.RB [ \fIpid\fB | \fIuser\fB]
-.br
-.B pstree
-.RB \-V
-.ad b
-.SH DESCRIPTION
-.B pstree
-shows running processes as a tree. The tree is rooted at either
-\fIpid\fP or \fBinit\fP if \fIpid\fP is omitted. If a user name is specified,
-all process trees rooted at processes owned by that user are shown.
-.PP
-\fBpstree\fP visually merges identical branches by putting them in square
-brackets and prefixing them with the repetition count, e.g.
-.nf
-.sp
- init\-+\-getty
- |\-getty
- |\-getty
- `-getty
-.sp
-.fi
-becomes
-.nf
-.sp
- init\-\-\-4*[getty]
-.sp
-.fi
-.SH OPTIONS
-.IP \fB\-a\fP
-Show command line arguments. If the command line of a process is swapped out,
-that process is shown in parentheses. \fB\-a\fP implicitly disables compaction.
-.IP \fB\-c\fP
-Disable compaction of identical subtrees. By default, subtrees are compacted
-whenever possible.
-.IP \fB\-G\fP
-Use VT100 line drawing characters.
-.IP \fB\-h\fP
-Highlight the current process and its ancestors. This is a no-op if the
-terminal doesn't support highlighting or if neither the current process
-nor any of its ancestors are in the subtree being shown.
-.IP \fB\-H\fP
-Like \fB\-h\fP, but highlight the specified process instead. Unlike with
-\fB\-h\fP, \fBpstree\fP fails when using \fB\-H\fP if highlighting is not
-available.
-.IP \fB\-l\fP
-Display long lines. By default, lines are truncated to the display width or
-132 if output is sent to a non-tty or if the display width is unknown.
-.IP \fB\-n\fP
-Sort processes with the same ancestor by PID instead of by name. (Numeric
-sort.)
-.IP \fB\-p\fP
-Show PIDs. PIDs are shown as decimal numbers in parentheses after each
-process name. \fB\-p\fP implicitly disables compaction.
-.IP \fB\-u\fP
-Show uid transitions. Whenever the uid of a process differs from the uid of
-its parent, the new uid is shown in parentheses after the process name.
-.IP \fB\-U\fP
-Use UTF-8 (Unicode) line drawing characters. Under Linux 1.1-54 and above,
-UTF-8 mode is entered on the console with \fBecho -e '\\033%8'\fP and left
-with \fBecho -e '\\033%@'\fP
-.IP \fB\-V\fP
-Display version information.
