There are some "specific interpretations" that _may_ be interpreted according to the C rules, e. g. prefix 0x- for hexadecimal or 08- for octal notation. For example, 083 != 83, just as 0x83 != 83. As it has been mentioned, spaces also have a significant meaning in crontabs, so they cannot be used everywhere to align data columns. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
