I am writing a ksh script and trying to extract some lines that come
after a particular line. Following is my sample file
================================================== =======================
Number of students in class are 50
Number of students with GPA>3.0 are 18
Some more lines

Last Name First Name
Class Date GPA
--------------------------------------------------------------------------------------------------------------------------------------
James Dave
xxxx xxxx xxxxxx
xxxxx xxxxx
xxxxx xxxxx xxxxxxxx
xxxxxxx xxxxxxxxxx
xxxxx xxxxxxxxxx xxxxxxxxxx

Professor: Dr. XYZ
School:XYZ
================================================== ==========================

I want all the lines that are below Last Name,First Name, Class,
Date,GPA heading but before Professorr. XYZ.

Any ?

Assuming there are some line-breaks in the above posting that are
non-existent in your actual data.

You can take the dashes and the empty line as separator...

awk '/^------------------/,/^$/' your-data-file

If the assumption is not valid, come back and ask.

Thanks Janis
It works. I didn't know that one can give two line saprators in awk to
limit the contents of an input file. Thanks again.
I have one more question about system() function in awk but I will ask
it in a new post.

Rachit.
