Sed/Awk - pull lines between pattern x and y

I've got some large CSV files where I'd like to extract all data between Line X that includes pattern 'x' and Line Y that includes pattern 'y'

For example:

other_data
Header
data
data
data
Footer
other_data

I want to be able to pipe everything between (and including) Header -> Footer to a new file.

Thanks!

This might work for you (GNU sed):

 sed '/^Header/,/^Footer/w new_file' file

Another way with awk:

awk '/Header/,/Footer/' file
Header
data
data
data
Footer

Just redirect the output to save in a newfile:

awk '/Header/,/Footer/' file > newfile

It's pretty straightforward in sed:

sed -n '/Header/,/Footer/p'

or

sed '/Header/,/Footer/!d'

Using awk it's pretty straightforward:

awk '/Header/ { show=1 } show; /Footer/ { show=0 }'

Basically keep state in a variable named show. When we hit the Header we turn it on, Footer we turn it off. While it's on, the show rule executes the default action of printing the record.
