Remove color codes (special characters) with sed

Matrix Style
I like the fact the Patola's version uses only ones and zeros, but I also like the sparse output of the other versions. This one combines both of those features and eliminates some unnecessary cruft. You can vary the sparseness by changing "$(($RANDOM % 5))" to another number. The number in this term "$(($RANDOM % 4))" controls how frequently the numbers are output bold.

Another way of do it in debian like distros, don't know if works for others

Shows all block devices in a tree with descruptions of what they are.
