Message-ID: <9@pixutl.UUCP> Date: Tue, 12-Nov-85 16:09:38 EST Article-I.D.: pixutl.9 Posted: Tue Nov 12 16:09:38 1985 Date-Received: Thu, 14-Nov-85 08:55:06 EST References: <121@rruxc.UUCP> Organization: Pixel Systems Inc., Woburn, Mass. Lines: 21 Keywords: uniformity of KSH's As long as we're talking about 'substring', 'expr' has a 'substr' option that used to be documented in V6. It goes: expr substr string n m where n is the first character of the sub-string and m the length. so: expr substr abcdefgh 2 4 gives: bcde 'expr' also has 'match', 'lentgh', and 'index' options that are not documented any longer. Anyone knows why?
