Unix Tip #4018- February 11, 2012

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;}'

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.
