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.

Display the history and optionally grep

Place this in your .bash_profile and you can use it two different ways. If you issue 'h' on its own, then it acts like the history command. If you issue:

h cd

Then it will display all the history with the word 'cd'

What others think

Nice. I use ! instead of 'h'.

Because bash won't allow a function called !, I create a function like yours and then:

alias !=h

Now I have:

! # show history ! cd # show all matching commands !! # last command as normal

@flatcap: using ! is very creative. I have not thought of it.

Comment by haivu 191 weeks and 6 days ago

This is a bit shorter and protects the grep from '-' character - so you can search for previous uses of option strings:

hist() { history |grep -- ${@:-.};}
