In linux, multiple Kill processes are often required to delete processes in batches. if these processes share common characteristics, you can Kill them with a command.

For example, clear all remote connection processes of the Oracle database: www.2cto.com ps-efww | grep LOCAL = NO | grep-v grep | cut-c 9-15 | xargs kill-9 pipe operator "|" is used to separate two commands, the output of the command on the left of the pipeline operator serves as the input of the command on the right of the pipeline operator. The following are several commands that are connected with pipeline characters: "ps-efww" is the command for viewing all processes in Red Hat 7.0. The retrieved process serves as the input of the next command "grep LOCAL = NO. The output of "grep LOCAL = NO" is that all processes with the keyword "LOCAL = NO" are common features of the remote connection process in Oracle databases. "Grep-v grep" is a process that removes the keyword "grep" from the listed processes. "Cut-c 9-15" refers to intercepting 9th to 15th characters of the input line, which is exactly the process id PID. The xargs command in "xargs kill-9" is used to take the output result (PID) of the preceding command as the parameter of the "kill-9" command and execute it. Sometimes there are a lot of processes found, all of which are dozens of columns. you can use aw matching printing and xargs kill-9 to kill them in batches at a time.
