It's weirder than that: $ echo 1 > f $ perl -pi -e 's/1/2/' f $ cat f 2 $ cat > foo <<\EOF #!/usr/bin/perl -pi s/2/3/; EOF $ chmod +x foo $ ./foo f Can't do inplace edit on f: Permission denied. $ ls f* f.bak foo $ mv f.bak f $ perl ./foo f Can't do inplace edit on f: Permission denied at ./foo line 1. $ ls f* foo $ ./foo <<EOF 2 EOF 3 I'm not sure why some invocations work and others fail, but the point is that update-copyright doesn't work as-is on cygwin 1.5; and it also has the annoying failure path of either renaming or worse deleting the original file. So I'm not sure how best to add skip logic to test-update-copyright to avoid spurious test failures. - -- Don't work too hard, make some time for fun as well!
