Calling a third party program from a perl script

Question

Perl

Tell me how to call a third-party program from a perl script and continue without waiting for it to finish?
exec? system?

if possible, an example.
For example, the task is to call from perl ... for example uname and continue without waiting for the end of the called process / program and the output. uname is just an example.

Answer 1

It is possible like this:

system("cmd &")

Answer 2

`/bin/sleep 10 &`

sleep is taken as an example ;)

Answer 3

for the task you describe it is enough just to use exec()

Answer 4

I would fork + exec
