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.

prevent accidents while using wildcards

alternative for "echo rm *.txt". Just doubletab the command you are willing to use and it will show you the affected files.

if you're using wildcards * or ? in your command, and if you're deleting, moving multiple files, it's always safe to see how those wildcards will expand. if you put "echo" in front of your command, the expanded form of your command will be printed. It's better safe than sorry.

Know a better way?

If you can do better, submit your command here.

What others think

This doesn't seem to be working for me in bash. It works in zsh however. Is there a setting to get it to work in bash?

Not working here either, Bash 4.00

Comment by kovan 199 weeks and 3 days ago

It works for me in 4.0.35. Make sure not to put a space after the txt

Comment by ProfessorTux 199 weeks and 3 days ago

There is something in my bashrc that is preventing it from working, but I don't know what it is (my bashrc has 250 lines).
