Use the ps command to view the startup location of a process file under Linux

 

Use the ps command as follows:

ps -ef | grep shutdown

Among them, shutdown is the shutdown command, but at this time, only the relative path is viewed, and there is no absolute path, such as:

Among them, 4170 is the process ID. At this time, enter [/proc/4170] and view it through ls -al as follows:

ls -al / proc / 4170

Notice:

• The cwd symbolic link is the process running directory;
• The exe symbolic link is the absolute path to the executable program;
• cmdline is the command line command entered when the program is running;
• environ records the environment variables when the process is running;
• Under the fd directory are symbolic links to files opened or used by processes.
