如何在Window或Linux/Unix中查找并干掉占用指定端口的进程
Windows
netstat /?
Displays protocol statistics and current TCP/IP network connections.
NETSTAT [-a] [-b] [-e] [-n] [-o] [-p proto] [-r] [-s] [-v] [interval]
-a Displays all connections and listening ports.
-b Displays the executable involved in creating each connection or
listening port. In some cases well-known executables host
multiple independent components, and in these cases the
sequence of components involved in creating the connection
or listening port is displayed. In this case the executable
name is in [] at the bottom, on top is the component it called,
and so forth until TCP/IP was reached. Note that this option
can be time-consuming and will fail unless you have sufficient
permissions.
-e Displays Ethernet statistics. This may be combined with the -s
option.
-n Displays addresses and port numbers in numerical form.
-o Displays the owning process ID associated with each connection.
-p proto Shows connections for the protocol specified by proto; proto
may be any of: TCP, UDP, TCPv6, or UDPv6. If used with the -s
option to display per-protocol statistics, proto may be any of:
IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.
-r Displays the routing table.
-s Displays per-protocol statistics. By default, statistics are
shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;
the -p option may be used to specify a subset of the default.
-v When used in conjunction with -b, will display sequence of
components involved in creating the connection or listening
port for all executables.
interval Redisplays selected statistics, pausing interval seconds
between each display. Press CTRL+C to stop redisplaying
statistics. If omitted, netstat will print the current
configuration information once.

taskkill /?
TASKKILL [/S system [/U username [/P [password]]]]
{ [/FI filter] [/PID processid | /IM imagename] } [/F] [/T]
Description:
This command line tool can be used to end one or more processes.
Processes can be killed by the process id or image name.
Parameter List:
/S system Specifies the remote system to connect to.
/U [domain/]user Specifies the user context under which
the command should execute.
/P [password] Specifies the password for the given
user context. Prompts for input if omitted.
/F Specifies to forcefully terminate
process(es).
/FI filter Displays a set of tasks that match a
given criteria specified by the filter.
/PID process id Specifies the PID of the process that
has to be terminated.
/IM image name Specifies the image name of the process
that has to be terminated. Wildcard '*'
can be used to specify all image names.
/T Tree kill: terminates the specified process
and any child processes which were started by it.
/? Displays this help/usage.
Filters:
Filter Name Valid Operators Valid Value(s)
----------- --------------- --------------
STATUS eq, ne RUNNING | NOT RESPONDING
IMAGENAME eq, ne Image name
PID eq, ne, gt, lt, ge, le PID value
SESSION eq, ne, gt, lt, ge, le Session number.
CPUTIME eq, ne, gt, lt, ge, le CPU time in the format
of hh:mm:ss.
hh - hours,
mm - minutes, ss - seconds
MEMUSAGE eq, ne, gt, lt, ge, le Memory usage in KB
USERNAME eq, ne User name in [domain/]user
format
MODULES eq, ne DLL name
SERVICES eq, ne Service name
WINDOWTITLE eq, ne Window title
NOTE: Wildcard '*' for the /IM switch is accepted only with filters.
NOTE: Termination of remote processes will always be done forcefully
irrespective of whether /F option is specified or not.
Examples:
TASKKILL /S system /F /IM notepad.exe /T
TASKKILL /PID 1230 /PID 1241 /PID 1253 /T
TASKKILL /F /IM notepad.exe /IM mspaint.exe
TASKKILL /F /FI "PID ge 1000" /FI "WINDOWTITLE ne untitle*"
TASKKILL /F /FI "USERNAME eq NT AUTHORITY/SYSTEM" /IM notepad.exe
TASKKILL /S system /U domain/username /FI "USERNAME ne NT*" /IM *
TASKKILL /S system /U username /P password /FI "IMAGENAME eq note*"
除了使用taskkill外，还可以通过快捷键Ctrl + Shift + Esc打开任务管理器，在它的“Process”或“进程”页签下找到对应的PID来结束任务！
