something is screw up with the console maybe, terminal setting are bad? Just a guess.
Are other command such as sin working properly or it’s just ls?
What if you do ls -l >file and then cat file, does the error shows up when catting the file. I have seen something like that when a 03 (CTRL-C) ended up in a corrupted file name.
The implication is that some text, probably a screwed up file name, is causing the interrupted call.
By viewing the output of “ls -l >file” in an editor, it might be obvious what the problem is.
It has something to do with number of files. Whenever I go to long listed files ls gives same type of response in my system and when the list is limited I dont get any such message.
