bug with ls command, doesn't list only a single directory.

[VIcente Palacios Barrera]

If is the only one which starts with an specified letter, won't show it with grep. Example: if there is only a directory starting with 'w', ls -l | grep ^[w] won't show it. With ls -l w* happens the same problem. I think you should check.

Did you mean ls -1?
ls -l is long listing,
does not start with filename,
Example can't work as written
