Oh, that might be true, I do remember encountering some escaping issues when creating a more complex POSIX (or bash) script that involved lists and iterating through stuff. I see Bash only uses commas in Brace expansions: file{1,2,3}.txt # file1.txt file2.txt file3.txt I guess it would only be a problem if you want to expand file,.txt file,,.txt file,,,.txt
