That would allow me to edit the command I'm entering, e.g. `,n'. What I'm suggesting is the command I'm entering can manipulate the in-line cursor when I press Enter to submit the command. I don't want interactive editing of lines in the file; I know where to find that. :-) > If GNU ed doesn't already have such support. ed 1.14.2-1 here hasn't. And I wouldn't expect its dependencies to grow. $ ldd /bin/ed linux-vdso.so.1 (0x00007fff215d4000) libc.so.6 => /usr/lib/libc.so.6 (0x00007fd89767a000) /lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007fd897a31000) $ -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
