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)
