One question and one tip
Question:
Do you intend to put the input file into the outputfile multiple times?
Tip:
VI fails to open files where file containts lines greater than some arbitrary
line length (usually around 2000 bytes). Since you are 'chop'ping off
the carriage returns on input, but not putting then back on output, you
will end up with an output file containing a single line of text...
Try this with an input file made up of say 10 lines, where each line it no
more than 5 characters. You should then see what is happening.
Also, a freebie:
When you 'CHOP' a line, you remove the last character. This allows you
to consume a line of input text in reverse. If the last character
was a newline
then you happen to achieve the same result as 'chomp'. If the last character
was in fact important data, you will lose it. Use CHOMP if you only intend
to strip newlines. Use chop if you want your input lines all one character
shorter, and you dont care what get chopped off the end.
