A method of fast viewing process PID in Linux system

A very simple command, pgrep, can quickly locate the PID of a process that contains a keyword; using this command, no longer use PS aux to go to which process PID

Usage:

Pgrep-l XXX

Description

-l parameter, which can display PID and process name; no-l show PID only, who knows what process PID

Example:

# pgrep HTTPD

2092

2094

2096

2098

2106

2108

2109

2111

# pgrep-l HTTPD

2092 httpd

2094 httpd

2096 httpd

2098 httpd

2106 httpd

2108 httpd

2109 httpd

2111 httpd

14705 httpd

Of course, the use of pgrep is not only so, interested students can study, but in my case, the application of a limited scope, in line with the principle of application, did not do too much study of pgrep.
