This article mainly introduces "CentOS to view the full path of the process running method". In the daily operation, I believe that many people have doubts about the method of viewing the complete path of the process running on CentOS. The editor has consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "CentOS to view the complete path of the process running". Next, please follow the editor to study!

When viewing process information through ps and top commands, only relative paths can be found, but details of processes that cannot be found, such as absolute paths, can only be found. At this point, we need to view the details of the process in the following ways:

When Linux starts a process, the system will create a folder named PID under / proc, and there will be information about our process under this folder, including a file named exe that records the absolute path, which can be viewed by the ll or ls-l command.

Ll / proc/PID

The cwd symbolic link is the directory where the process runs.

Exe symbolic connection is the absolute path to execute the program.

Cmdline is the command line command entered when the program is running

Environ records the environment variables when the process is running

The fd directory is the symbolic link to the files opened or used by the process.

At this point, the study on "CentOS to view the full path of the process running" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
