Question

Was wondering how I can start up a command such as:

while :; do ./myCommand; done;

But instead of doing the usual

screen -S nameOfMyScreen

Then the command

while :; do ./myCommand; done;

Then detach the screen

^a ^d (Control "a" the control "d"

I would like it to start and detach. Thanks!

Answer 1

screen -d -m sh -c "while :; do ./myCommand; done;"

Explanation:

• -d -m starts screen in detached mode (create session but don’t attach to it)
• sh -c commandline starts a shell which executes the given command line (necessary, since you are using the while builtin).
