How to properly grep filenames only from ls -al

Question

How do I tell grep to only print out lines if the "filename" matches when I'm piping through ls? I want it to ignore everything on each line until after the timestamp. There must be some easy way to do this on a single command.

As you can see, without it, if I searched for the file "rwx", it would return not only the line with rwx.c, but also the first three lines because of permissions. I was going to use AWK but I want it to display the whole last line if I search for "rwx".

Any ideas?

EDIT: Thanks for the hacks below. However, it would be great to have a more bug-free method. For example, if I had a file named "rob rob", I wouldn't be able to use the stated solutions.

drwxrwxr-x 2 rob rob  4096 2012-03-04 18:03 .
drwxrwxr-x 4 rob rob  4096 2012-03-04 12:38 ..
-rwxrwxr-x 1 rob rob 13783 2012-03-04 18:03 a.out
-rw-rw-r-- 1 rob rob  4294 2012-03-04 18:02 function1.c
-rw-rw-r-- 1 rob rob   273 2012-03-04 12:54 function1.c~
-rw-rw-r-- 1 rob rob    16 2012-03-04 18:02 rwx.c
-rw-rw-r-- 1 rob rob    16 2012-03-04 18:02 rob rob

Answer 1

The following will list only file name, and one file in each row.

$ ls -1     

To include . files

$ ls -1a 

Please note that the argument is number "1", not letter "l".
