Bash脚本在Ubuntu 16.04上更新GO项目[重复]

This question already has an answer here:

guys. I am new to bash scripting and deploying Go on ubuntu. I run my Go program like this

go build -o myprogram main.go
./myprogram &

But now, instead of uploading files with sftp and manually change everything I wanted to write simple bash script.

The problem is that I firstly need to kill existing process and I don't know how to get PID and kill it.

Maybe I can run my program using something different so I don't have to find PID.

I tried using ps ax | grep myprogram and then kill it, but no luck

    bash has a special variable $! that you can use to store the process id of the most recently started background process

    ./myprogram &
    myprogram_PID=$!
    
    kill "$myprogram_PID"
