More useful commands in the Linux command-line:. In this video, I cover commands that are useful for filtering and narrowing output, putting to use all the shell-skills we've built up so far. && - the logical AND operator, useful for running things IF something else is successful. cut - divide output into two fields and select one of them. sort - sort items (by alphabetical order, etc.) uniq - only show unique output (duplicates not shown) wc - "word count." Count lines, letters, etc. grep - the very basics of this unbelievably powerful searching/pattern-matching command.
