I'd really like to understand what the problem is, why 'tr' barfs, and what the 'locale' settings have to do with this. Thanks.
tr on Mac OS seems to assume input is valid UTF-8 text (if locale is suitably UTF-8). You can set your tr string to something trivial and it still barfs: dd if=/dev/urandom bs=1 count=256 2>/dev/null | tr -dc 'A-Za-z0-9' | head -c 32 A portable hack might be to use iconv to say that the input is an 8-bit charset: dd if=/dev/urandom bs=1 count=256 2>/dev/null | iconv -f ISO-8859-1 | tr -dc 'A-Za-z0-9!@$%^&*(){}[]=+-_/?\|~`' | head -c 32 cheers, Stewart
