comment console space eaten up by file contents
Not all distributions use RPM package manager, so that is useless information as long as we don't know the distribution.

vim is called with vi from the command line. Many distributions, including Ubuntu, have vim-tiny installed by default which again is simply called from the command line by typing vi. One of the habits of vim-tiny is the effect as described above.

comment “error: no such device” at boot in Ubuntu Server 11.10 with Raid1
You might want to check cat /proc/mdstat. Both RAID sets should show up, including rebuilding progress.

comment Fork bomb on a Mac?
My conclusion is that I'm über-smart ;o) Personally I'd rather higher a limit when I need it than accidentally crashing my system because of a typo. And you are right about the file. I always confuse the two.

Maybe good to mention: the ulimit can be made to survive a reboot by configuring it in /etc/sysctl.conf.

comment Fork bomb on a Mac?
Still I think it is a foolish default that most distributions allow a fork bomb from unprivileged users to DoS a machine.

sudo: rlimit: command not found. What I mean to say: It rlimit is not part of standard the (ubuntu) distribution, I know Gentoo didn't use it either couple of years back.

comment Fork bomb on a Mac?
Fork bombs have been around like for ever. This is indeed a very simple protection against fork bombs, but by far most of the Linux distributions do not implement it. Not sure why, but I think it has something to do with limiting trusted user processes too.

I would advise using $NF (always referring to the last field) instead of $9.

Are you trying to store your file on a FAT32 filesystem?

comment Run a given command on every subpath of a long path
So use the variation with bash, but instead of piping it to bash redirect it to a file. Remove the unwanted lines, then execute the file. find /a -type d -exec echo chmod g+x {} \; > /tmp/my_commands.sh followed by vi /tmp/my_commands or a smart grep ... . then . /tmp/my_commands to execute the lines. Just don't forget the echo or all commands will be executed right away.

comment Is there any way to set Mac OS X to use xinetd instead of launchd?
I'm not a Mac expert, but why would you want to change something potentially so fundamental to the workings of the machine?

comment Keeping track of the latest releases
If 'latest and greatest' is your goal, be prepared to do a lot of system debugging and you'll have a lot of build and installation headaches.

comment mbcache documentation
I took a peek at the source code, but the comment isn't really helpful. The userland tools are not mentioned at all (but that is no surprise). Hopefully the mbcache project will share documentation shortly.

comment How can I fake sending -time when sending email with Mutt?
The professor should not accept the time that the email was sent, but the time the email arrived in his/hers mailbox. It is up to the student to deliver the information in time; maybe email is not the best medium in this case. I think tampering with email headers is called 'fraud'.

Try it from a liveCD, and try to mount the filesystem. Gheck dmesg for errors.

Did you try a fsck of the root filesystem? Boot from a liveCD, then do the fsck.
