I was reading about the different ways to run rsync. It looks like
connecting to an rsync deamon is very similar to connecting to an
rsync shell like ssh.
Are there situations where the deamon is superior to the ssh? Are

I have a file with over 500 MAC addresses. Each address is on a new line. However, the MACs do not have ":"
I need a script that will read the file, line by line and insert colons in the addresses and then print the results to a new file.
current.txt looks like this

I would prefer to use Sed, but I will do whatever necessary. I want to know a good way to remove ":" and "/" from the first string surrounded in Double quotes, but not the 2nd.

escape(1) Mail Avenger 0.8.3 escape(1)NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
