Rats! the command line above got chopped off as it had a less than redirection symbol, sanitising the input.

cpio -ov --format=crc (less than symbol here)/tmp/dumplist | dd obs=128k of=/dev/st0

I hope this gets though.

I too am left handed, but can happily do many things with either hand.
(Writing being the one exception. It's either poorly with the left hand, or atrociously and very slowly with the right.)

My mouse buttons are in the standard right handed configuration regardless of which hand I use, and it's never caused me any difficulty.

I do however hate the fact that mouse designers create all sorts of right-handed ergonomic designs, but left handed designs are exceedingly rare.
Even so-called "Ambidextrous" mice often have side buttons on the left hand side only, where they fall under a right-hand thumb, but are all too annoying when moving the mouse left handed.

I did however manage to convert most of the staff at an accounting firm I deal with to left handed mousing (the staff there being predominantly right-handed). The reason is simple. An accountant spends a lot of time on the numeric keypad, so mousing with the left hand leaves their right hand free to use the keypad. They very quickly noticed the improvement in throughput.

You have to take these little victories when they come your way.
