Running shell script in parallel

Question

I have a shell script which

1. shuffles a large text file (6 million rows and 6 columns)
2. sorts the file based the first column
3. outputs 1000 fi

Answer 1

You might wanna take a look at runp. runp is a simple command line tool that runs (shell) commands in parallel. It's useful when you want to run multiple commands at once to save time. It's easy to install since it's a single binary. It's been tested on Linux (amd64 and arm) and MacOS/darwin (amd64).
