I am using RHEL.  If I have a file a.a, and it contains the following:

first item
second item
third item

... and I want to add a line at the end of the file, and perform something like

concatenate  a.a  "fourth item"

and the result would look something like

first item
second item
third item
fourth item

(Note, this will requiree a CR)

What command would I use to perform this

Hello,

I typically use VI to edit text files.
vi a.a

Open in new window

In VI, it opens as read-only.  To edit, press I for insert.  Then it becomes editable.  Place the cursor at end of line 3, then press Enter for new line.  Add desired text.  Then press Shift+; to call a command line at bottom of file, then type wq and press Enter to save and close file.  "wq" stands for write;quit.

If you want to familarize yourself with all of VI's commands, see this link:
