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

Remove ( color / special / escape / ANSI ) codes, from text, with sed

Credit to the original folks who I've copied this command from.

The diff here is:

Theirs: [m|K]

Theirs is supposed to remove \E[NUMBERS;NUMBERS[m OR K]

This statement is incorrect in 2 ways.

1. The letters m and K are two of more than 20+ possible letters that can end these sequences.

2. Inside []'s , OR is already assumed, so they are also looking for sequences ending with | which is not correct.

This : [a-zA-Z]

This resolves the "OR" issue noted above, and takes care of all sequences, as they all end with a lower or upper cased letter.

This ensures 100% of any escape code 'mess' is removed.

sed -r "s/\x1B\[([0-9]{1,3}((;[0-9]{1,3})*)?)?[m|K]//g
