Whitespace in the $PATH may be mangled. This: echo "$PATH" will reserve that. I think -d (delimiter, yes?) is less portable than -r (raw - don't parse backslashes). Also, on some platforms (SysVish) echo may interpret backslashes as well (\c - no newline, \n - a newline char, etc), which is why I went for: printf "%s\n" "$PATH" which avoids that. Personally I think the IFS based solution suggested elsewhere in the thread is better - it's totally portable and also faster.
