While that may be true, it does not take much imaginination to see that another's circumstances may create such a need, or a desire. That said, I do not (and did not) want to denigrate the use of vi(m), mg, emacs or whatever, if someone feels the need for a screen editor, just like I would not want to denigrate the use of Ted, KWord, or whatever, if someone feels the need for a word processor. These appear to me as personal choices. cheers, -wb
editors in floppy44.fs (OpenBSD 4.4.) - newbee help
Hello list, I did manage to scr... err, mess up partitioning scheme through disklabel, so I've booted from floppy, mounted partitions to /tmp/a/, tmp/d/, /tmp/e/, but when I attempt to edit etc/fstab by ed I get: #chmod 766 /etc/fstab # ed /etc/fstab 215 q # I've arrived there by adding new partition for /var and editing /etc/fstab without executing newfs on new partition. When I then attempted to clean the mess up by running disklabel again, I mixed up /usr and old /var, so I guess I'm stuck to floppy now. Any help (obviously written for dummies) is greatly appreciated. I've never used ed. Other than that, 4.4. is great (as far as I saw until now...which isn't much as you can guess). Song rocks, too.

As long as your filesystems are still readable, you can use a more comfortable tool: mount /dev/wd0a /mnt mount /dev/wd0d /mnt/var mount /dev/wd0e /mnt/usr /mnt/usr/sbin/chroot /mnt vi (or mg) /etc/fstab you could possibly even just copy your fstab from your freshly mounted /var (/var/backups/etc_fstab.*) CK On Sat, Nov 1, 2008 at 1:27 PM, Edd Barrett [EMAIL PROTECTED] wrote: On Sat, Nov 1, 2008 at 7:33 PM, soko.tica [EMAIL PROTECTED] wrote: Hello list, I did manage to scr... err, mess up partitioning scheme through disklabel, so I've booted from floppy, mounted partitions to /tmp/a/, tmp/d/, /tmp/e/, but when I attempt to edit etc/fstab by ed I get: #chmod 766 /etc/fstab # ed /etc/fstab 215 q # That is ed doing its job :) Go to the OpenBSD web siite and find the manual page section.

If you have a running system, try 'man ed'; otherwise, point any browser at http://www.openbsd.org/cgi-bin/man.cgi?query=ed It may not be everyone's first choice for a big interactive editing task, but ed is small, fast on any machine, easy to script and always there. cheers, -wb

I did figure it out myself meanwhile, but since I already started bombing the list with stupid questions, I wanted to put proper path in my initial question in the hope someone might search for it in future. The most obvious superior feature of OpenBSD to us newcomers is systematic and logically connected documentation that would make you learn and understand. That's unlike Linuces I had a chance to use before. After I collect myself in one piece after this experience, I'm back again to play with unpartitioned part of my HDD and adjust the partitions to my imagination/needs. Now I'll remember disklabel + newfs and then to edit /etc/fstab.

I end up using vi from somewhere I don't remember whenever I boot in single user mode. I guess it needs /tmp and /usr mounted or something. Once again I need to check this. But the fact that NFS mount is available in base install and ramdisks is quite cool... -Girish
