Hello, I am new to Scientific Linux, but wanted to point out changes I had to make to 'make.dvdiso.sh' for my version of 'tail.' At the line: disc=`tail +4 $idir/.discinfo | head -1` I had to change it to: disc=`tail -n +4 $idir/.discinfo | head -1` and at the line: tail +5 .discinfo.orig >> .discinfo I had to change it to: tail -n +5 .discinfo.orig >> .discinfo I am sure other people have found this, but I just wanted to point it out just in case. Regards, Murrah Boswell
