I know better than to try to convert you :-) and I can see how it might be a close call for some, but I see it as an improvement: the original: 3 types of quotes and 8 quote characters total no s.quotes: 2 types of quotes and 4 quote characters, and none in proximity > One can remove the surrounding quotes of sed arguments: > sed -e s/\\/[^/]\*\$// > but it doesn't become more readable this way. Of course not. BTW, that's probably not what you meant. You should quote the square brackets, too, otherwise the shell may interpret them. The difference in your sed example is that removing the quotes requires adding _more_ syntax (backslashes) to protect each and every shell meta-character. The version without single quotes is far less readable and not maintainable. However, with the tr strings above, there is no need for additional quoting, so the result is a net decrease in syntax.
