# From arnold@f7.net Wed Dec 15 11:32:46 2004 # Date: Tue, 14 Dec 2004 14:48:58 +0100 # From: Stepan Kasal <kasal@ucw.cz> # 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 }
