Ps and grep lookup eliminate grep self lookup and psgrep lookup eliminate

It is very convenient to use ps-def | grep to find the process. The last line will always grep itself.

$ Ps-def | grep dragonfly-frameworkdean 5273 5272 0 00:00:00 pts/5 newlisp. /dragonfly-framework/newlisp-redirection.lsp-http-d 8080-w. dean 5491 5229 0 00:00:00 pts/16 grep -- color = auto dragonfly-framework

You can use the grep-v parameter to exclude the grep command. Therefore, you can modify the version as follows:

$ Ps-def | grep dragonfly-framework | grep-v grepdean 5273 5272 0 00:00:00 pts/5 newlisp./dragonfly-framework/newlisp-redirection.lsp-http-d 8080-w.

Extract the process ID with awk.

Ps-def | grep dragonfly-framework | grep-v grep | awk '{print $2}' 5273
