Let me think about that. I wasn't aware that \0 couldn't get into a filename. I was concerned about the following in /http://www.dwheeler.com/essays/filenames-in-shell.html : ========================================= "Most shells cannot store byte 0 in a variable at all. You can’t even pass such null-separated lists back to the shell via command substitution; cat $(find . -print0) and similar “for” loops don’t work. Even the POSIX standard’s version of “read” can’t use \0 as the separator (POSIX’s read has the -r option, but not bash’s -d option)." ========================================= > It's not like it's that hard to do this properly in a policy compliant > POSIX shell, either.
