The latest versions of gawk and sed appear to have changed how they process DOS text STDIN. This change in behavior has broken some of our scripts. Is this change in behavior by design? Can we revert back to the old design?
Pls see test cases below. -- thanks, Tom Rodman # -------------------------------------------------------------------- # Normal behavior for many past revs of cywgin's gawk and sed: # o sed is *not* binary in pipes (it converts DOS text to UNIX) # o awk is binary in pipes (it leaves line terminators alone) # # NOTE that "printf" test below sends 1 DOS line of text (\r\n), and 1 UNIX line # -------------------------------------------------------------------- ~ $ date;uname -a Wed Apr 5 12:43:46 CDT 2006 CYGWIN_NT-5.2 OurSrvr063 1.5.19(0.150/4/2) 2006-01-20 13:28 i686 Cygwin ~ $ cygcheck -c|egrep 'gawk|sed' gawk 3.1.5-2 OK sed 4.1.4-1 OK ~ $ printf "hi\r\nho\n"|eval sed '/foo/d'|od -c 0000000 h i \n h o \n h i \n h o \n 0000006 ~ $ printf "hi\r\nho\n"|eval awk '{print}'|od -c 0000000 h i \r \n h o \n h i \r \n h o \n 0000007 # -------------------------------------------------------------------- # Problem behavior for new gawk and sed # o sed is now binary in pipes (it leaves line terminators alone) # o awk is *not* binary in pipes (it converts DOS text to UNIX) # -------------------------------------------------------------------- ~ $ date;uname -a Wed Apr 5 12:53:56 CDT 2006 CYGWIN_NT-5.0 OurServer108 1.5.20s(0.155/4/2) 20060329 23:02:10 i686 Cygwin ~ $ cygcheck -c|egrep 'gawk|sed' gawk 3.1.5-4 OK sed 4.1.5-1 OK ~ $ printf "hi\r\nho\n"|eval sed '/foo/d'|od -c 0000000 h i \r \n h o \n 0000007 ~ $ printf "hi\r\nho\n"|eval awk '{print}'|od -c 0000000 h i \n h o \n 0000006 -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
