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

sed "s,\x1B\[[0-9;]*[a-zA-Z],,g"
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.
Sample Output
user@host:~$  echo aaa | grep --color=always a | sed "s,\x1B\[[0-9;]*[a-zA-Z],,g"
aaa

# Note:  The a's are colored by grep, then color is stripped by sed statement.

What Others Think

This is the only one that works with multiple codes, I tried the rest, and they miss several codes. Absolutely brilliant.
