My favorite:

Same commands listed in different fashion:

Legend:

  • a all users, without a only current user
  • f shows in tree fashion like pstree (forest), without f normal output
  • w & ww are for output width, with ww it wraps the lines, with a single w (or no w) it doesnt wrap. can achieve similar wrapping with just using | nl (however it adds line numbers on left column)
  • e shows environment variables, without e doesnt show environment variables

The end.
