Moving around

• pwd displays the current working directory.

  For example,

  % pwd
  /home/vastro

• cd directory changes from the current to the new directory, if it exists.

  For example,

  % pwd
  /home/vastro/test
  % cd plots
  % pwd
  /home/vastro/test/plots
  % cd $\sim$
  % pwd
  /home/vastro
