comment Delete space-expanded “tab” in Vim with one keystroke?
IMO this is exactly what the OP asked for. Deserves more upvotes.

comment Way to avoid ssh connection timeout & freezing of terminal tab
Thanks sblair for helping me with the wording, it's much appreciated. I changed "should not" back to "must not" because ssh checks the permissions of the file and if it is world or group readable it fails.

comment ubuntu 10.10 - Get rid of the Desktop directory in home
Thanks Gilles, I did just that and it works. I'm concerned however that some day I accidentally drop something on the desktop and wonder where it went because I don't remember where I hid the folder:-).

Thanks pootzko. Apparently there was a bug report and subsequent fix in 2007 (--no-desktop). Unfortunately it doesn't work anymore.

It's probably nautilus, but how can I turn it off?

"SWAP is only used when absolutely necessary." - sorry, no, that's not the case: kerneltrap.org/node/3000

comment How do I convert a Linux disk image into a sparse file?
What about cat then? There is nothing in the man page about sparse files, so I assume cat /dev/zero > zero.file is perfectly OK to fill empty space with zeros?

comment Been away from linux for 10 years. Which commands have I missed?
You use git more often then cd. That is kind of cool.

comment Movie colors are off on ubuntu
This solved the problem for me, except that hue slider position is the exact oposite. I'm pretty sure that the hue slider is on the left per default. In my case colors are OK when I move the hue slider to the middle.

Thanks Josh, it's really there and the md5 matches the file I downloaded:-)

I must be blind. Where exactly is the MD5SUM file? It's not in cdimage.debian.org/debian-cd/5.0.4/i386/bt-cd

comment Getting a Cross-Section from Two CSV Files
Note to self: Never post, not even a one-liner, without having tested it;-). I have incorporated your suggestions in my answer. Sorry for the confusion.

comment Getting a Cross-Section from Two CSV Files
@Nate: Per default the command joins on the first (space delimited) field. The easiest fix is to use a character that isn't in your file (maybe #) as a field delimiter, like this: join -t# -v2 file1.csv file2.csv >result.csv Another thing I just realized is that your input files have to be sorted for join to work properly.

comment Getting a Cross-Section from Two CSV Files
@Jonathan Sampson: You can use a pipe to write it in a file like so: join -v2 file1.csv file2.csv > result.csv

comment Getting a Cross-Section from Two CSV Files
Sorry, -a2 is a right outer join. If you only want the unpairable lines it's -v.

comment How to find the executable files under a certain directory in linux?
If you have an old version of find (probably before 4.3.8) which lacks -executable use find . -perm /u=x,g=x,o=x.

comment Gparted doesn't detect any partitions
Before you mess with fdisk you should consider to backup your old (broken) partition table, just in case fdisk does more harm than good.

comment bash history is appended, but histappend is off
@quack: I have upgraded this install several times, so I'm not 100% sure. For me it doesn't matter if histappend is on or off, history is always appended. What I'm really curious about is why this happens? It would be insightful, if you could shopt -u histappend and tell me if it is still appended in your install?

comment bash history is appended, but histappend is off
echo $PROMPT_COMMAND returns echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD/$HOME/~}\007". trap -p returns nothing. I have no /etc/bash.logout and ~/.bash_logout contains nothing regaring history.
