Getting the last word from the previous command
This is (perhaps surprisingly) very useful!
Create a directory for yourself using mkdir:
mkdir /fs/ess/PAS1855/users/$USER/rnaseq_intro/sandbox/testdirMove into this dir using cd – after typing cd and a space, press Alt+. on Windows or Esc+. on a Mac:
cd /fs/ess/PAS1855/users/$USER/rnaseq_intro/sandbox/testdirAnother press will go back to the last word of the second-to-last command, and so on. On Windows, you can keep Alt pressed while repeatedly pressing . (convenient), but on a Mac, you’ll need to release Esc in between successive presses.
