ECHO LINES TO A BLANK

To echo all lines in a file upto the first blank line use the following:

awk '$0 ~ /^$/ {exit;} {print $0;}' <file_name>

The awk script can be used for printing lines upto the first occurence of any pattern.

Just substitute ^$ with the pattern.

I wrote this script to parse http server headers.
