shell 脚本中&和&&的区别

2023年5月11日 257次阅读来源: Jalon

& means “run command in the background.
“command1 && command2 means “run command1 and if it completes successfully, run command2 afterwards.”So you should probably use &&. You would use & if you want both commands to run simultaneously.

a & b 表示a和b同时运行
a && b表示 a运行成功后再运行b
