sum and average of requests responses times or sizes in Apache2 access log

Depending on your Apache access log configuration you may have to change the sum+=$11 to previous or next awk token. Beware, usually in access log last token is time of response in microseconds, penultimate token is size of response in bytes. You may use this command line to calculate sum and average of responses sizes. You can also refine the egrep regexp to match specific HTTP requests. Show Sample Output

Capture screen and mic input using FFmpeg and ALSA

Now we can capture only a specific window (we have to chose by clicking on it) ffmpeg complains about "Frame size must be a multiple of 2" so we calculate the upper even number with (g)awk trickery. We remove the grep, we are already using (g)awk here ....why losing time with grep !!! ;) Show Sample Output

Print data from field 9 till the end separated by a white space and new record separated by newline.

It'll print the file names preserving the spaces in their names and adding new line after every new filename. I wrote this to quickly find out how many files in any directory is owned by a particular user. This can be extended using pipe and grep to do much more. Show Sample Output

awk '{for (i=9;i<=NF;i++) {printf "%s",$i; printf "%s", " ";}; printf "\n"}'

Get the Nth argument of the last command in $HISTFILE

This gets the Nth argument in the last line of your history file. This is useful where history is being written after each command, and you want to use arguments from the previous command in the current command, such as when doing copies/moving directories etc. I wrote this after getting irritated with having to continually type in long paths/arguments. You could also use $_ if all you want is the last argument. Show Sample Output

Burn an audio CD.

My variation on an audio burning command from commandlinefu - this one doesn't crap out if you want to burn a CD in a directory whose permissions don't allow it, and instead rips everything to /tmp. If you mount your music partition like I do using Samba, you probably don't have write permission inside that file system in order to create the temporary directory other audio burning commands here use. Not a bad idea to add cdrom to your groups, and /bin/eject with visudo.
