Linux finds the process with the specified name and displays the process details

In practice, there might be a scenario where a process name feature string is given to find details of all processes that match the process name.

The solution is to:

(1) the pgrep [str] command is used for fuzzy matching, and the process ID matching the feature string is found;

(2) Second, according to the process ID display the specified process information, PS--pid [PID];

(3) Because the found process ID needs to be passed as a parameter to the PS command, so use the Xargs command, through the pipe symbol connection;

(4) Finally show the process details, you need to add the-u parameter.

The final command shape is as follows:

Pgrep Java | Xargs ps-u--pid
