Run commands in new terminals, then kill later-CodePudding

I have a start.bat similar to the following:

start npx tailwindcss -i ./www/src/styles/main.css -o ./www/dist/styles/main.css --watch
start caddy run

It launches 2 new cmd prompts and starts processes within them (which both run indefinitely). Is there a way for this bat file to send a kill command to the cmds it spawned? Ideally I'd have a single command to kill all "child" processes which were created.

CodePudding user response：

set "wintitle=my process %time%"
start "%wintitle%" npx tailwindcss -i ./www/src/styles/main.css -o ./www/dist/styles/main.css --watch
start "%wintitle%" caddy run

....

taskkill /FI "WINDOWTITLE eq %wintitle%"

[untested] - should work in theory...

A PowerShell solution, using the Start-Process and Stop-Process cmdlets:

$processes = & {
  Start-Process -PassThru npx 'tailwindcss -i ./www/src/styles/main.css -o ./www/dist/styles/main.css --watch'
  Start-Process -PassThru caddy run
}

# ...

# Stop (kill) all launched processes.
$processes | Stop-Process
