This is much easier to parse and do something else with (eg: automagically create ZFS vols) than anything else I've found.

First, the command searches the output of

ls -l /dev/disk/by-id

for "wwn-". It then searches for three letters, followed by the end of a line via the command

egrep "[a-zA-Z]{3}$"

It then replaces "../../" with nothing (separating the three letters out)

From there, it removes all of the permission and user information via

|sed -E 's/.*[0-9]{2}:[0-9]{2}\s//'

Then it removes the arrows -> via

sed -E 's/->\ //'

Afer that, it sorts the output on column 2 (the disk letters) with

sort -k2

From there, it reverses the order of the columns so that our disk letter comes first via

awk '{print $2,$1}'

Finally, it replaces the space separating the two columns with a tab using

sed 's/\s/\t/'

For large ZFS pools, this made creating my vdevs immeasurably easy. By keeping track of which disks were in which slot (spreadsheet) via their serial numbers, I was able to then create my vols simply by copying and pasting the full output of the disk (not the letter) and pasting it into my

This command creates an unmirrored pool using

files. While not recommended, a pool based on files can be

useful for experimental purposes.
