# Subject: gawk bug with RS="^..."
# To: bug-gawk@gnu.org
# Message-id: <20041214134858.GA15490@matsrv.math.cas.cz>
#
# Hello,
# I've noticed a problem with "^" in RS in gawk. In most cases, it seems
# to match only the beginning of the file. But in fact it matches the
# beginning of gawk's internal buffer.
#
# Observe the following example:
#
# $ gawk 'BEGIN{for(i=1;i<=100;i++) print "Axxxxxx"}' >file
# $ gawk 'BEGIN{RS="^A"} END{print NR}' file
# 2
# $ gawk 'BEGIN{RS="^Ax*\n"} END{print NR}' file
# 100
# $ head file | gawk 'BEGIN{RS="^Ax*\n"} END{print NR}'
# 10
# $
#
# I think this calls for some clarification/fix. But I don't have any
# fixed opinion how the solution should look like.
#
# Have a nice day,
# Stepan Kasal
#
# PS: See also the discussion of the issue in the comp.lang.awk newsgroup.
BEGIN { RS = "^A" }
END { print NR }
