how to use at command to schedule browser opening at a scheduled time

Question

how to open Mozilla browser home page in 2 mins of current time using the at command on command line?

Answer 1

sleep 120; firefox; Is correct.

But to clarify:

• sleep is counted in seconds so sleep 120 is what you need for it to wait 2 minutes.

• Then firefox is what you need to open a browser.

If you'd like it to open say Google, the command is

firefox https://google.com
