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?
Piping changes vim's stdin and causes problems. Try this instead (for bash, zsh, etc.):
vim $(find . -name "*.cpp")
How about vim *.cpp?
Maybe for file in *.cpp; do vim "$file"; done could work too. Edit each file and exit.
Or start vim and add all cpp files with following command: :argadd *.cpp
When using Vim in a pipe like this, you'll probably notice the following warning:
Vim: Warning: Input is not from a terminal
That's Vim telling you that it cannot function as it's supposed to be (i.e. in interactive mode; you can still use it in "batch mode" by feeding it Ex commands to process). That explains the weirdness you experience after Vim quits.
