jobsis a shell builtin. It tells you about the jobs that the current shell is managing. It can give you information that is internal to the shell, like the job numbers (which you can use in shortcuts like fg %2) and the original command line as it appeared before variable expansions.
jobs是一个内置的shell。它告诉您当前 shell 正在管理的作业。它可以为您提供 shell 内部的信息，例如作业编号（您可以在诸如 之类的快捷方式中使用fg %2）和出现在变量扩展之前的原始命令行。
psis an external command which can tell you about all the processes running on the system. (By default it only shows a small subset, but there are options to select larger sets of processes to display.) It doesn't know about the shell-internal stuff.
ps是一个外部命令，它可以告诉您系统上运行的所有进程。（默认情况下它只显示一个小的子集，但有选项可以选择更大的进程集来显示。）它不知道 shell 内部的东西。
