Get the /dev/disk/by-id fragment for a physical drive

This was tested on Ubuntu 12.04 (Precise) LTS Server. It returns the name of the symlink within /dev/disk/by-id for the physical drive you specify. Change /dev/sda to the one you want, and replace ata- with scsi- or the appropriate type for your drive.

I used this to pre-configure grub-pc during a non-interactive install because I had to tell it which disk to install grub on, and physical disks don't have a UUID such as that blkid provides.

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.
