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.

Remove ANSI colors from stream or file

Know a better way?

If you can do better, submit your command here.

What others think

Useless use of cat.

Sed can read the file instead..
