jobs 示例
jobs
显示所有正在运行的作业。输出类似于以下内容：
[1] + Stopped (user) top
在这里，作业1已被用户暂停，在本例中的过程是顶级实用程序。
jobs -l
当提供-l选项时，jobs除了显示作业编号外，还会显示进程ID，类似于以下输出：
[3] 16882 Running ./chsearchproc (wd: ~/public_html/cgi-bin/chsearch)
jobs
Displays all running jobs. Output is similar to the following:
[1] + Stopped (user) top
Here, the job number 1 has been suspended by the user, and the process in this case is the top utility.
jobs -l
When supplied the
-l option,
jobs displays process IDs in addition to job number, similar to the following output:
[3] 16882 Running ./chsearchproc (wd: ~/public_html/cgi-bin/chsearch)
