Solaris process management and process management

Cmd command to generate a process. The start time of the Stime process, ppid, parent process id, and tree structure.

Process start mode: Manual start and scheduling start.

Manual start: it can be divided into front-end and back-end (add one more at the end of the line, with space), process scheduling in front and back-end, jobs, fg, bg.

Jobs checks the fg job number of the background process and transfers the background process to the foreground. Ctrl Z: Move the foreground process to the background and stop it. If you want it to continue running, add the bg job number.

Crtl + C interrupts the command being executed.

Kill + pid to Kill the specified process.

Kill-l lists all processes.

Botnets: they do not run and occupy resources. Orphan process: running, occupying resources. The parent process died and was adopted by init 1.
