Expires: Quoted from <4289@sun.uucp> ["Re: Variations across unices"], by guy@sun.UUCP... +--------------- | Yes to the first (for some reason, the S5 and, I think, S3 versions of "tr" | require the square brackets) and no to the second (the "1" refers to the | first argument, and is not a numeric value). +--------------- Not System III. +--------------- | Unless there was a good reason to incompatibly change the syntax of "tr" | from what AT&T's own V7 supported, one could argue that the USDL perpetrated | a bad joke on us all by doing so.... +--------------- My theory was that either (1) since character ranges are [x-y] in other programs, they should be that way in tr just to make all programs act the same way, or (2) [x-y] makes it possible to easily translate a hyphen. I prefer (1); it makes a kind of (skewed, but what's new with AT&T?) sense. --Brandon -- ihnp4!sun!cwruecmp!ncoast!allbery ncoast!allbery@Case.CSNET ncoast!tdi2!brandon (ncoast!tdi2!root for business) 6615 Center St. #A1-105, Mentor, OH 44060-4101 Phone: +01 216 974 9210 CIS 74106,1032 MCI MAIL BALLBERY (part-time)
