Hi,

There's lots of ways to do this, here's one:
for line in `cat tempfile`; do echo "\'$line\'"; done

this seems like homework, just read up on "sed" it will teach you how to do it.

So long as the file isn't ridiculously large, I'd do it in vi/vim

How would do it with vim. I know that in vim "." would repeat the last operation but here we are doing the '898282', so it involves 3 operations, I am just trying to understand if there is any better approach to solve the problem.

Actually, in the general case, the previous answers are better.
I was just offering an option for changing the content of the file, rather than the output.
Depends on exactly what you want.

vim cmds

Code:

#all start of line => ' (insert)
:%s/^/'/

#all end of line => ',  (append)
:%s/$/',/

You'd just manually delete last ','

Actually, for the latter, you can specify the line range (specify start & end line nums) to edit, thus avoiding last comma.

Code:

:1,3s/$/',/
