xxd not found in Recovery Mode, Mac OS X 10+ In Recovery Mode, I was trying to access my password hashes, except bash 3.2 returned command not found for xxd. 

Any help would be appreciated.
The recovery partition neither contains xxd nor od. Use the one installed to the main OS X volume by entering:

/Volumes/NameOfMainVolume/usr/bin/xxd


Don't forget to escape spaces in the name of your main OS X volume with a backslash. If you want to save something to a file also use your main volume. The Base OS X you are booted to is read-only and all the smaller r/w disks with less than ~50 MB are lost after a restart because they are in RAM.
