set UserName = $<
vi ./subscribers
A $UserName
:! :wq

how would one take input from a variable and append it to the end of a
line within a text file? I tried the above, and needless to say, it doesnt
work. the one hitch is that is must append the text to the end of one
contiguous line with no carriage returns. any suggestions?
