How to disambiguate vim commands from shell commands

阅读更多关于 How to disambiguate vim commands from shell commands

问题 From How to easily escape a command-line filter: And actually, this has been a bit of an XY problem. I'll have to post the original problem in a different question, though, because the Y question is really interesting and I would like to know. I'll post a link to the X question in the comments.

阅读更多关于 using xargs vim with gnu screen

问题 I've got a weird problem where if i do something like this in a gnu screen window, that window starts responding in weird ways ls *.cpp | xargs vim After I exit from vim, the screen window doesn't echo any command. It even does not echo CR. Any suggestions? 回答1: Piping changes vim's stdin and causes problems. Try this instead (for bash, zsh, etc.): vim $(find . -name "*.cpp") 回答2: How about vim *.cpp ?

问题 I need to highlight anything beyond column 72 with a different background color. What's the best method? Something similar to a visible line margin that some editors do is also good.
