Unix屏幕实用程序错误:找不到'xterm-256color'的termcap条目 [英] Unix screen utility error: Cannot find termcap entry for 'xterm-256color'

问题描述

我通过Mac上的ssh连接在NetBSD系统上工作，我想使用screen实用程序，以便我可以启动过程并在终端连接中断后返回到它们.当我键入screen时，我收到错误消息:

I work on a NetBSD system through an ssh connection from my Mac and I want to use the screen utility so that I can start processes and come back to them after my terminal connection has been interrupted. When I type screen I get the error message:

Cannot find termcap entry for 'xterm-256color'

浏览论坛帖子后，我认为这与远程计算机上的termcap有关，但事实并非如此.我可以启动屏幕，而另一台计算机(通常是我无法访问的另一台计算机)的ssh会话中没有错误.这表明我需要在本地计算机上进行配置，但是我无法弄清楚什么或如何进行.尽管这篇文章被标记为"gnu-screen"，但我怀疑我正在使用Berkeley屏幕，尽管我不知道这是否有显着区别.

After looking through forum posts, I thought it had something to do with termcap on the remote machine, but that appears not to be the case; I can initiate screen with no errors from an ssh session from another computer, one to which I don't generally have access. This suggests that I need to configure something on my local machine, but I haven't been able to figure out what or how. Although this post is tagged "gnu-screen" I suspect that I'm working with Berkeley screen, though I don't know whether that is a significant distinction.

推荐答案

快速修复:运行TERM=xterm screen而不是screen.

Quick fix: run TERM=xterm screen instead of screen.

您收到此错误，因为在Mac上您具有TERM=xterm-256color，而xterm-256color不在远程计算机的termcap中.从另一台计算机连接时，不会出现错误，因为它的TERM变量设置为其他变量.

You get the error because on your mac you have TERM=xterm-256color, and xterm-256color is not in the remote machine's termcap. You don't get the error when you connect from the other computer because it has its TERM variable set to something else.
