Re: How to do an array?

I am going to ask this here. Part belongs in this users group and
part in another. I have a html file that consists of several hundred
lines such as the group below. To store the data on the server, am I
correct to say an array is created and for this example the array
has a name of 'describe[]'?

<div style="text-align: center;"><h2>Personal Data</h2></div>
<p>Your Name:&nbsp;&nbsp;<input type=text name=describe[] size="40%"
maxlength=256>
Tel:&nbsp;&nbsp;<input type=text name=describe[] size="30%" maxlength=16>
Date of Report:&nbsp;&nbsp;<input type=text name=describe[] size="10%"
maxlength=16></p>
<p>Your Address:&nbsp;&nbsp;<input type=text name=describe[] size="60%"
maxlength=1024>
E-Mail:&nbsp;&nbsp;<input type=text name=describe[] size="30%"
maxlength=1024></p>
</body>

I need to fill the [] with a number. I had wanted to write a shell script
to do that. I have googled for 2 days and have yet to discover how
to increment a numerical variable in 'sed'.

Use awk, not sed, e.g.:

awk 'BEGIN { n = 1 }
{ while ( sub(/[[][]]/,"[" n "]" ) ) ++n ; print }
' FILENAME > NEWFILE

Can someone help me or more importantly, tell me where the tutorial is
that will
answer these question.
