Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Use the 'comm' command

Comment by thewtex 204 weeks and 5 days ago

The 'comm' command is part of gnu coreutils and you have it if you have 'diff'. This is how you can do it with comm:

comm -1 -2 input.file1 input.file2
