The Shell script monitors the running status of a specified process.

The Shell script monitors the running status of a specified process.

This article mainly introduces how to monitor the running status of a specified process using Shell scripts. This article provides the script code directly. For more information, see

In the previous blog, I wrote the implementation method of the automated testing program. Now developers need to know the process to be tested (here it refers to the main process running on LINUX) the running status of the process before exiting, such as memory usage and CPU usage.

A shell script is used to run the specified process. Directly add the code.

The Process status is read every 10 seconds, and then displayed. when the process is found to exist and the status is not Z (non-zombie), continue monitoring, however, when the test program is executed or unexpectedly exits, the script also exits the monitoring loop and then prints the status of the specified process.
