Thanks you are right, it worked with a ls -1 not l....new to this, never used ls -1 before. I need to go find out the difference

Note: ls -1 is the same as ls, when the output is not a terminal, so the -1 option is unnecessary here.

hmmm what does not a terminal mean?

Also the command I ran changed it in the response...but not permanently so when I do a ls -l I still see the old name, even though the command seemed to have changed it from the response

When we issue the command
Code:
ls

the output is to a terminal and it looks something like this:
Code:
$ ls
file1	file12	file15	file18	file20	file23	file3	file6	file9
file10	file13	file16	file19	file21	file24	file4	file7
file11	file14	file17	file2	file22	file25	file5	file8

But when we output the command to a file or a pipe for example, the output looks like this:

Code:
$ ls | cat
file1
file10
file11
file12
file13
file14
file15
file16
file17
file18
file19
file2
file20
file21
file22
file23
file24
file25
file3
file4
file5
file6
file7
file8
file9

Here ls is the same as ls -1
