Old boy Education daily-101th Day-How do I find out which directory the process is in by port?

Reference Answer:

First step-Find the number of the process that corresponds to the port

[[email  protected] ~]# ss -lntup |grep :22tcp    LISTEN      0      128                    :::22                    :::*        users: (("sshd", 1467,4) tcp    listen     0       128                     *:22                     *:*       users :(("sshd", 1467,3)) 

Step Two-show/proc/process number/CWD directory

[Email protected] ~]# ls-l/proc/1467/cwdlrwxrwxrwx 1 root root 0 June 01:25/PROC/1467/CWD

Process number/Other commonly used files in this directory:

CWD Symbolic link is the process running directory;
EXE symbolic connection is the absolute path to execute the program;
CmdLine is the command line command that is entered when the program is run;
Environ records the environment variables when the process is running;
The FD directory is a symbolic connection of the files that the process opened or used.

User Answer

3. Enter Ls-ail, the result of the EXE link is the full path of the executable file details
