'''Many''' newcomers to [Expect] wonder about how it compares to [Tcl]. [[explain simplicity. Expect is just a superset of Tcl with additional functionality in three domains. Refer to articles. Point out that [many people who think they need Expect do not need Expect]. If you can do something with Tcl, you necessarily can do it with Expect; it's just an [extension].]] What Expect gives the developer is a few new commands that are specifically oriented to dealing with setting up pseudo terminals ([pty]s), examining the returning output of a command, etc. Most of what you write, however, is just Tcl. ----- [Category Expect] [http://www.labelcan.com/ 标签]
