Hiroshi found another bug. Currently sed's $ triggers at end of every file,
and with multiple files SuSv3 says it should only trigger at the end of the LAST file. The trivial fix I tried first broke if the last file is empty. Fixing this properly required restructuring things to create a file list (actually a FILE * list), and then processing it all in one go. (There's probably a smaller way to do this, merging with append_list perhaps. But let's get the behavior correct first.) Note that editing files in place (-i) needs the _old_ behavior, with $ triggering at the end of each file. Here's a test of all the things this patch fixed. gnu and busybox seds produce the same results with this patch, and different without it. echo -n -e "1one\n1two\n1three" > ../test1 echo -n > ../test2 echo -e "3one\n3two\n3three" > ../test3 sed -n "$ p" ../test1 ../test2 ../test3 sed -n "$ p" ../test1 ../test2 sed -i -n "$ p" ../test1 ../test2 ../test3
