O que significa o & quando usado no final de um script bash?

Question

Eu uso um script bash para lançar e adicionar um & ao final, assim:

O que significa o símbolo & no final?

Obrigado.

    

Answer 1

Diz ao sistema para executar o comando em segundo plano. Da página man bash do meu sistema:

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0. Commands separated by a ; are executed sequentially; the shell waits for each command to terminate in turn. The return status is the exit status of the last command executed.
