[mrtg] Re: MRTG and Linux

[Brian E. Seppanen]

the tr command in unix/linux translates characters, so you would do

#man tr
 or
#info tr

info tr has much more documentation.

That being said you could do something like this, utilizing unix/linux's
great redirection/piping capabilities

cp mrtg.cfg mrtg.cfg.test
cat mrtg.cfg.test | tr -d \r > mrtg.cfg.good
                 PIPE       REDIRECT -> new file

However, you see actual occurrences of ^M, so you may have to use escape
characters, and not actually remove newlines.  the \ is an escape
character.  so this might work tr -d \^M.  You may have to play aroud
with the pattern matching a bit.  If you need more background on what tr
is doing you might  also want to look at sed, awk, grep as each of these
delve heavily into pattern matching.  sed may actually be better at doing
what you propose.  Man is man's best friend.

Don't mean to sound patronizing, I just have no idea how comfortable with
linux/unix you are.

hope that helps.
