How to do an array?

[Dave Kelly]

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'.

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

TIA
Dave

There are many ways to store things on a server, but all envolve writing
to files. What one language describes as an array another might describe
as a structure or list or something else. Your question about an array
has no general meaning given the data that follows.

<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>

What I *think* you *might* be trying to do is some kind of templating.
Forget sed. Use Perl or Python or Ruby templating facilities. Google
"perl template," "python template," etc.

Use awk, not sed, e.g.:

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