Oh something else to note, 'cat' doesn't read an entire line in, but rather
something that is better classified as words. Here's the code again:
for line in $(cat twtest.txt); do
sed "s|^$line|#$line|" twpol.txt > twpol.txt.new
mv twpol.txt.new twpol.txt
done
The first iteration will contain "Filename:" and will be matched again
twpol.txt but won't match anything. It'll then continue and $line will
contain whatever was after Filename: which would be "/sbin/accton". The the
3rd run it'll go to line #2, word #1 which is Filename: again and the 4th run
is line #2 word #2 which is the filename /scsi/proc and so on.
Maybe rename the line variable to 'chunk' or 'word' or something.
