Linux acquires JMeter PID and kill with Boot

There are some differences between the interactive shell and shell scripts of Linux, mainly because of the existence of a separate running process, so there is a difference between the acquisition process PID.Interactive Bash Shell get process pid

With the known process name (name), the interactive Shell gets the process PID in a number of ways, typically by using grep to get the PID (where the-v grep is added to avoid matching to the grep process):

ps -ef | grep "name" | grep -v grep | awk ‘{print $2}‘

Or do not use grep (where the initials are added [] to avoid matching the process to awk itself):

ps -ef | awk ‘/[n]ame/{print $2}‘

If you use only the x parameter, the PID should be in the first place:

ps x | awk ‘/[n]ame/{print $1}‘

The simplest way is to use pgrep:

pgrep -f name

If you need to find the PID and kill the process, you can also use Pkill:

pkill -f name

If the program is executable, you can use pidof directly.

pidof name
