My problem is that the Bash shell stops showing the characters I type into it. It does read the commands though.
I've come across this problem quite a few times and I don't understand what causes it. I know how to solve it, but I really don't like it when I'm "voodooing" my way of out of problems.
I'll describe the two ways I've come across this problem:
I'm running a certain process, http://pythonpaste.org/script/ and sometimes when I stop that or it breaks control is given back to the shell. When I then go and type commands into the shell, the characters I type don't show up. When I press enter the commands are submitted. So for example:
- I type "ls"
- I only see an empty prompt and nothing more
- I press enter and I'm given a listing of the files, in other words: the command is executed
- when I give the "reset" command the shell starts working normally again
The second way this happens is when I give a command like this:
$ grep foo * -l | xargs vim
I use grep to find files that have a certain pattern and then I want to open all the files that result from the grep. This works like a charm (although not as fast as I'd hoped). But when I exit Vim my shell stops showing the characters I type into it. A reset command resolves the problem.
My guess is that both problems have an underlying reason, but I'm kind of stumped on how or what that reason is.
Searching for this problem is itself problematic because the description is kind of vague and has no hard search-terms for it.
