It looks quite a bit better/more comprehensive than expr I also see that bash has swiped Perl's =~ operator and now understands POSIX regexes as well Thanks for the heads-up. I should reread manpages a bit more often BTW, in the dim, dark past I've also used strongly typed command languages: ICL's 2900 command language was both typed and block structured: the best thumbnail description I can give is that it was effectively Algol 68 with i/o and type declarations removed and panoramic conditionals added. It could be run line by line as you typed it in or written as a text file and compiled. Yes, you did declare types variables before using them. IBM's OS/400 did more or less the same though it wasn't quite so powerful. The similarity shouldn't be surprising because both OSen were designed in the late 60s/early 70s and both were for new mainframe architectures. ICL's 2900 series replaced the 1900 series while IBM's Future Series was meant to replace the 360/370 range but got cancelled and then resurrected over a decade later as the AS/400 range, now known as iSeries. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |
