| Ok, interesting results -
|
| 1. it got rid of all comments fine
|
| 2. it placed a space between EVERY character in the new file
Yeah, reread my paragraph; it looks above like the spaces have been
mangled. To repeat:
Be careful with the cut/paste. The sed command has in the quotes, _two_
spaces then one space then _three_ spaces then one then one.
You've got exactly one space each time. So:
s/ */ /g
will replace 0 or more spaces. I had
s/ */ /g
with _three_ spaces, meaning _2_ or more spaces get replaced.
| 3. I still have a bunch of duplicate lines right next to each other.
Can you post a few such dups?
Cheers,
