Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

eh () { history -a ; vi ~/.bash_history ; history -r ; }
2011-03-23 18:00:20
Functions: vi

eh stands for Edit History


Frequently, I'll mistype a command, and then step back through my history and correct the command. As a result, both the correct and incorrect commands are in my history file. I wanted a simple way to remove the incorrect command so I don't run it by mistake.


When running this function, first the ~/bash_history file is updated, then you edit the file in vi, and then the saved history file is loaded back into memory for current usage.


while in vi, remember that `Shift-G` sends you to the bottom of the file, and `dd` removes a line.


this command is different than bash built-in `fc` because it does not run the command after editing.

sed -r 's_(/[^>]*?>)_\1\n_g' filename.html
2011-03-12 14:35:52
Functions: sed

Finds all the closing tags in a HTML document via non-greedy regex and adds a linefeed for easier reading/editing


sed -i.bak -r 's_(/[^>]*?>)_\1\n_g' filename.html


This will save a copy of filename.html as filename.html.bak and then add the linefeeds to the original file
