Format USB FreeBSD gpart

  • Locate devices:

    camcontrol devlist

    Output; in this case only:

    <ST3500418AS CC35>                 at scbus3 target 0 lun 0 (pass0,ada0)
    <ST500DM002-1BD142 KC45>           at scbus5 target 0 lun 0 (pass1,ada1)
    <AHCI SGPIO Enclosure 1.00 0001>   at scbus9 target 0 lun 0 (ses0,pass2)
    <Generic STORAGE DEVICE 1532>      at scbus10 target 0 lun 0 (da0,pass3)
    <Generic STORAGE DEVICE 1532>      at scbus10 target 0 lun 1 (da1,pass4)

    Where ada0 and ada1 are mechanical drives, da0 is a miniSD card in a USB enclosure da1

    Or to print all partitions:

    gpart show

    Output (after formatting USB device):

    List partitions on dev da0:

    gpart show da0

    Delete existing partitions:

    gpart delete -i da0

    Destroy label:

    gpart destroy da0

    Create new mbr spanning entire disk:

    gpart create -s mbr da0

    Create new fat32 partition spanning entire disk:

    gpart add -t fat32 da0

    Initialize fat32 file system:

    newfs_msdos -F32 /dev/da0s1

    Lets break something!

    Don’t do any of this unless you are prepared to break it all, or better yet, you read the man pages and find out what they actually do, very useful tools however.

    I’m just making notes from other notes, various resources on the net.

    gpart destroy -F da0

    Zero out the drive === !!!Don’t do this jazz regularly on any USB!!! The type of memory has a finite read/write number===

    dd if=/dev/zero of=/dev/da0 bs=2m count=1

    Format the drive

    newfs_msdos -F32 /dev/da0s1

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).
