Input Handling

By default, concurrently doesn't send input to any commands it spawns.
In the below example, typing rs to manually restart nodemon does nothing:

$ concurrently 'nodemon' 'npm run watch-js'
rs

To turn on input handling, it's necessary to set the --handle-input/-i flag.
This will send rs to the first command:

$ concurrently --handle-input 'nodemon' 'npm run watch-js'
rs

To send input to a different command instead, it's possible to prefix the input with the command index, followed by a :.
For example, the below sends rs to the second command:

$ concurrently --handle-input 'npm run watch-js' 'nodemon'
1:rs

If the command has a name, it's also possible to target it using that command's name:

$ concurrently --handle-input --names js,server 'npm run watch-js' 'nodemon'
server:rs

It's also possible to change the default command that receives input.
To do this, set the --default-input-target flag to a command's index or name.

$ concurrently --handle-input --default-input-target 1 'npm run watch-js' 'nodemon'
rs
