Haynes) Newsgroups: comp.unix.bsd.netbsd.misc Subject: Question about sed on different systems Date: 22 Jan 1997 19:45:06 GMT Organization: University of California, Santa Cruz Lines: 9 Message-ID: <5c5qo2$c2j@darkstar.ucsc.edu> NNTP-Posting-Host: hobbes.ucsc.edu Xref: euryale.cc.adfa.oz.au comp.unix.bsd.netbsd.misc:5223 I've just asked this on comp.std.unix to find out what is canonically correct. Meanwhile maybe someone can explain the following echo -n "AX" | sed -e 's/X//' produces an A on NetBSD and nothing on SunOS 4.1.4 I'm guessing the difference is something in the C library, as I compiled sed from the GNU sources on both platforms. echo -n "AX" > foo produces an identical file on both (verified by od -bc foo).
