Two methods for batch process deletion in linux

Two methods for batch process deletion in linux are described. The process to kill has a common string. [Plain] kill-9 'PS-ef | grepxxx | awk & amp; #39; {print $2} & amp; #39; the symbol behind 'kill-9' is the one above the Tab key. The above is kill-9'. two methods are described to list the batch deletion processes in linux. The process to kill has a common string. [Plain] kill-9 'PS-ef | grep xxx | awk '{print $2} ''after kill-9 is the one above the Tab key. The above is kill-9' to list the processes, find the line containing xxx, and output the pid columns 'kill, ps, grep are very common commands. Awk is used to output a column. {print $2} is the second output column. the above is the pid column. Here is an awk tutorial at http://www.2cto.com/ OS /201307/230381.html. [Plain] the ps-ef | grep xxx | grep-v root | awk '{print $2}' | xargs kill-9 grep-v parameter is used to exclude a character. Therefore, the commands executed by root are excluded. Then we use awk to find the pid column. The final xargs is a program that obtains parameters from the standard output and executes the command, that is, it obtains the output from the previous command as a parameter to execute the next command.
