Hi,

I have a web2 file that I would like to change all occurrences of coffee to chocolate  only on the lines starting with a 2. Using the sed command.

The following link includes examples that may enhance your current use of sed.
http://www.unix.com/shell-programming-scripting/59127-search-replace-restriction-awk-sed.html

the above example will output the results after processing the file.

You can use vi/vim with /^2\./ s/coffee/chocolate/ to achieve the same goal.
vi -c  '/^2\./ s/coffee/chocolate/|wq' filename
note that coffees will also be replaced with chocolate to end up with chocolates.

add g if there are multiple replacements per line (same applies to sed) i.e.
vi -c  '/^2\./ s/coffee/chocolate/g|wq' filename
