[2]+ Done... 是什么意思？
当在后台执行的程序结束时，会提示诸如+ Done...
- Done ...
Done ...
请问这里+,-,或者空分别代表什么意思？ man bash的JOB CONTROL段:In output pertaining to jobs (e.g., the output of the jobs command), the current job is always flagged with a +,andthepreviousjob with a -.A single % (with no accompanying job specification) also refers to the current job.current job的解释:the current job, which is the last job stopped while it was in the foreground or started in the background.
