First question is:

How can I insert my dynamic ip address from a file called 'add' that has only
my ip address in it into the line below where it says NOT.ON.LINE.NOW
How can I replace my

<p>My current IP address is &lt;<B><I>NOT.ON.LINE.NOW</B></I>&gt;</p>
<p>Last automatic update: <B><I><$DateTime></B></I></p>

Next question is:
Once I insert my ip address into the above line, how do I replace the address
with another address.

<p>My current IP address is &lt;<B><I>206.3.12.2</B></I>&gt;</p>

I need a replace type command such as: replace $1 with $2.

I found this in the sed man page but I don't know how to go about using it

[2addr]y/string1/string2/
             Replace all occurrences of characters in string1 in the pattern
             space with the corresponding characters from string2. Any charac-
             ter other than a backslash or newline can be used instead of a
             slash to delimit the strings.  Within string1 and string2, a
             backslash followed by any character other than a newline is that
             literal character, and a backslash followed by an ``n'' is re-
             placed by a newline character.

sed 's/NOT.ON.LINE.NOW/'`cat add`'/g' master > current.html

: I would suggest that you would best be suited by having 2 copies of the file,
: the 'current' one and the 'master' one. You can then say
: sed 's/NOT.ON.LINE.NOW/'`cat add`'/g' master > current.html

Nope; the one character that can be guaranteed to be in an html file is the
forward slash.

<p>My current IP address is &lt;<B><I>NOT.ON.LINE.NOW</B></I>&gt;</p>
<p>Last automatic update: <B><I><$DateTime></B></I></p>
