I want to make a web page that has a text box with a send button.

How should the html line be edited to send the text to the script as a variable 'a' and then store it in a variable in the script located at /usr/lib/cgi-bin?

HTML

<textarea name="comments" cols="50" rows="6">
Enter text here...
</textarea><br>
<input type="submit" value="send" >
<form action="/usr/lib/cgi-bin/s1.sh" method="post">
</form>

To execute s2 what changes should be made to the following code/tag.
s2 will print the first line to the screen.

action="/usr/lib/cgi-bin/s2.sh" method="post"

Scripts:

s1). After entering text and clicking the send button the web page should send the text lines as a variable i.e 'a' to a script s1 which would store the text to a file.

#!/bin/sh
a //for this I think a has to be declared in html tag.
$a>/home/../f1

s2) The script s2 will take the first line from the file f1 , display it on screen.

a=`head -n 1 f1`
echo $a

Or execute s1 while the user is typing by the code
'read a' but thats not what I want and even that doesnt work.something might be wrong with the html tag.

Btw here is what happens after I type text and press the enter code

It simply opens the form_reader script(the s1 script with a changed name) and there isn't anything written to tf as well.
this is with the following edited html code/tag.

<html>
<head><title>Title</title></head>
<body>
<form action="/usr/lib/cgi-bin/form_reader" method="post">
Enter data:<input type="text" name="data"><br>
<input type="submit">
</form>
</body>
</html>
