I am not either, but this seems a case for an unnecessary hard link (unless I am missing something obvious, so feel free to be pedantic). We are just talking here about: a. The same man page (ed.1), which is hard-linked to red.1 for unknown reason. b. The same executable (ed), which is hard-linked to red (for me for unknown/dubious benefit). But lets examine the latter and test if red works the way it have to, by just create a symbolic link from ed to red. The man page is out of question, it hasn't to be a hard-link. ============================================================ [ag][627](~t)which red /usr/bin/red [ag][628](~t)file =red /usr/bin/red: symbolic link to `ed' [ag][629](~t)pwd /tmp [ag][630](~t)touch test.txt [ag][631](~t)ed test.txt -s <<< $'i\nThis is\na test\n.\n,p\n,w' This is a test [ag][632](~t)echo $? 0 [ag][633](~t)red test.txt -s <<< $'$a\nThis is \nanother test\nfor red\n.\n,p\n,w' This is a test This is another test for red [ag][634](~t)echo $? 0 [ag][635](~t)mkdir test && mv -v test.txt test `test.txt' -> `test/test.txt' [ag][636](~t)red test/test.txt -s <<< $'$a\nLets test if it \nworks\n.\n,p\n,w' ? [2]ag][637](~t)echo $? 2 ============================================================ So it works the way it is supposed to work (by denying to edit the file), because that file is in a different directory than $(pwd), as red is a restricted ed. It just works that way, when you just invoke it as red. This is the same case with rvim/rview/gvim and many other applications, see: [ag][638](~t/test)ll /usr/bin/rv* lrwxrwxrwx 1 root root 3 2008-02-20 21:26 /usr/bin/rview -> vim* lrwxrwxrwx 1 root root 3 2008-02-20 21:26 /usr/bin/rvim -> vim* Finally, I've had a look what other distributions do, and they all do symbolic links. I hope I covered the case, as it seemed to me so obvious when I fixed it, that it didn't deserve a discussion or a ticket. -- http://wiki.linuxfromscratch.org/blfs/wiki/Hacking -- http://linuxfromscratch.org/mailman/listinfo/blfs-book FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
