Linux finds the full path of the launcher based on the process number PID

Transferred from: http://blog.csdn.net/lsbhjshyn/article/details/18764613

Working environment encountered network is not normal, detection is a server exception to send packets, using the netstat command to view, found a program. This process state of IptabLex is an exception connection. Cannot be effectively purged, so you want to know which directory this program is in zombie state.

[Email protected]/]# NETSTAT–ANP | Less

When the problem occurs, the status of the process is:
[[email protected]/] PS x

The way to find a process startup path is:
1. We can get the PID of the zombie process from the PS command, as in the above example 23347
2. Enter the directory named under the PID in the/proc directory
3. Enter Ls-ail, the result of the EXE link is the full path of the executable file details
[[email protected]/] ls/proc/found 23347 folders

[[email protected]/] cd/proc/23347

[[email protected] 23347] Ls–ail

Can find this connection has an exception, the corresponding application is also a problem, the rest is to find a way to delete the application of this zombie process, is generally redundant or garbage program, can rm-f kill ...

You can also view the command path by Lsof-p PID
