Run shell command and don't wait for return

linuxbashshell

提问by Nimjox

Is it possible to start the execution of a command and not wait for it to return before continuing.

是否可以开始执行命令而不等待它返回才继续。

I.E.

IE

commands
/usr/sbin/thing.sh    <-- Don't wait for this to return.
more commands

A single &symbol between commands will let each run independently without relying on the previous command having succeeded.

&命令之间的单个符号将使每个命令独立运行,而不依赖于前一个命令是否成功。

hydrogen:tmp phyrrus9$ cat shell.sh 
#! /bin/sh

echo hello
sleep 15 &
echo world
hydrogen:tmp phyrrus9$ ./shell.sh 
hello
world
hydrogen:tmp phyrrus9$ ps -a
PID   TTY        TIME    CMD

12159 ttys000    0:00.22 -bash
12611 ttys000    0:00.00 sleep 15
12612 ttys000    0:00.01 ps -a

Append the & to the end of the command. Tested on:

将 & 附加到命令的末尾。测试:
