Vim: Terminal Integration

#vim  #linux 

Vim and Terminal!?

Vim was made to work with the command line. Many beginners do not understand what are the true capabilities of Vim, myself included:) Vim can run terminal commands without leaving the text editor, open an instance of a terminal, work with shell environments, and other things depending on the use case.

Running Terminal/ shell commands from within Vim

You can run the commands from inside of Vim by just using :! before the command, this means you have to be in command mode. Just after being in command mode, the ! or bang operator will execute the command typed after it from the terminal(Linux/ macOS) or your default shell(Windows -> CMD/Powershell).
