Tmux Commands

screen and tmux

A comparison of the features (or more-so just a table of notes for accessing some of those features) for GNU screen and BSD-licensed tmux.

The formatting here is simple enough to understand (I would hope). ^ means ctrl+, so ^x is ctrl+x. M- means meta (generally left-alt or escape)+, so M-x is left-alt+x

It should be noted that this is no where near a full feature-set of either group. This - being a cheat-sheet - is just to point out the most very basic features to get you on the road.

Trust the developers and manpage writers more than me. This document is originally from 2009 when tmux was still new - since then both of these programs have had many updates and features added (not all of which have been dutifully noted here).

  • Mount NFS from Truenas

    mkdir -p /media/rick/pool1 chown -R rick:rick /media/rick/pool1

    Add the automount to: /etc/fstab

    truenas.thecave:/mnt/pool1 /media/rick/pool1 nfs user,auto 0 0

    Retstart Nautilus to see the share in files:

    killall nautilus

    For other shares, just repeat the same process under directory ‘media’ with the name of the share substituted

  • Again running smartctl after all is said and done:

    smartctl --all /dev/sda

    ddrescue-smartctl-after-rescue.png ddrescue-smartctl-2.png

    Yet an old drive in itself, I run the wheels off of them, and monitor regularly as anyone should.
