Making a bootable usb stick ...

  diskutil list
  diskutil eraseDisk <filesystemtype> <partitionname> <diskidentifier>
  diskutil unmountDisk <diskidentifier>

Examples

  sudo dd if=/Volumes/Cave/Users/axes/Desktop/lubuntu.iso of=/dev/disk4 bs=1m
  sudo dd if=/Users/me/tails-i386-1.3.iso of=/dev/rdisk9 bs=16m && sync

Insert USB drive into PPC Mac of choice, depress command-option-o-f (open firmware)
try usb0, usb1, usb2, etc. until it works and finds the port you used for the img

  probe-usb
  boot usb0/disk@1:2,\\yaboot
  boot usb1/disk@1:2,\\yaboot 

once inside the yaboot shell, some common examples are:

  install url=mintppc.org
  install
  cli  
  cli-expert
  cli64
  cli64-expert

32bit EFI 64bit .iso notes for GNU/Linux installs 

  hdiutil convert -format UDRW -o destination_file.img source_file.iso
  diskutil list
  diskutil partitionDisk /dev/disk1 1 "Free Space" "unused" "100%"

Particularly helpful is partitioning as GPT from command line in macOS:  

  diskutil partitionDisk /dev/disk2 GPT JHFS+ New 0b
  
Back to writing the image to the partition with dd:
  
  dd if=[Directory/to/udrw/img] of=/dev/disk1 bs=1m
  diskutil eject /dev/disk2

First, disable Gatekeeper because it is stupid - use Terminal

  sudo spctl --master-disable

Second, disable System Integrity Protection (SIP) because it is stupid and won't let you dual boot properly.  Reboot your Mac, holding down command + r, and once in the recovery OS, open a Terminal and enter:

  csrutil disable

Now, reboot your Mac normally and enter a Terminal.
  
  cd ~
  wget https://sourceforge.net/projects/refind/files/0.11.2/refind-bin-0.11.2.zip
  unzip refind-bin-0.11.2.zip
  cd refind-bin-0.11.2
  sudo ./refind-install
  sudo reboot

PATH Location on macOS

  /Sometimes they are installed by default in opt
#(although this can be changed by an --option)etc/paths (location of PATH on Mac)
  /etc/man.path (man page paths)

Force Empty Trashes 
  sudo rm -rf ~/.Trash/*
  sudo rm -rf /Volumes/*/.Trashes

Showing hidden items in Finder

  defaults write com.apple.finder AppleShowAllFiles TRUE
  killall Finder


-------------------------------------------

Hiding Users in macOS.  First, create an admin user in System Preferences.  

  sudo dscl . create /Users/shortnameofuser IsHidden 1
  sudo mv /Users/shortnameofuser /var/shortnameofuser
  sudo dscl . -create /Users/shortnameofuser NSFHomeDirectory /var/shortnameofuser
  sudo dscl . -delete "/SharePoints/shortnameofuser's Public Folder"
  sudo reboot

Locate bitcoin wallet private key from Bitcoin-qt console:

  walletpassphrase [enterpassword]
  dumprivkey [enter public address from gui]

-------------------------------------------

To add shell scripts to Terminal command, open bash.rc, and add this to the fields (first create a directory for your scripts):

  export PATH="/path/to/dir:$PATH"

#Then, restart Terminal by:

  source .bashrc

#I also added the directory of my shell scripts to the path directory

  cd Volumes/Cave/etc/
  nano edit paths 

#Then add a line to the scripts folder:

  /Volumes/Cave/Users/axes/Scripts

#To make a script executable (not tested yet - old commands in fodler)

  chmod +x yourshellscript.sh
