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.

@Jonathan Sampson: You can use a pipe to write it in a file like so: join -v2 file1.csv file2.csv > result.csv

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.
