As I understood it, the ISOs are GPL, but you can't describe them as "RedHat" because that trademark is being enforced very heavily. I wonder if we'll start to see people offering "a certain RPM-based distribution 7.3" or similar soon. You probably know that I'm not a great fan of that distribution and I'm not exactly unhappy to see its owners doing things to harm its share of the GNU/Linux market. -- MJR

Plus seems to be slower than sprintf(), especially with a high enough number of decimal places required. Implementing it as a generic "reduce to n d.p." would probably require one exponent to an unknown, and not base 2, so probably not terribly easy for a compiler or interpreter to optimize.

Sure, and printf is synonymous to print sprintf(). (It would seem fairly logical for printf to feed the value of sprintf() into print() and not interpret the values itself.)

Javascript, perl script, anyscript help please....
by Simon 07 May '02

07 May '02

Hi Guys, I'm looking for a method of scrolling a HTML page up and down without user intervention... I know of the window.scroll method in Javascript, but I can only get it to scroll down... The purpose is so a page with monitoring data (MRTG graphs) can gently scroll up so all the graphs are displayed over a period of time... Any ideas ??? Simon

window.scrollTo(x, y); with x and y set to 0 should take you back to the top. __________________________________________________ Do You Yahoo!? Everything you'll ever need on one web page from News and Sport to Email and Music Charts http://uk.my.yahoo.com

Any "expect" gurus out there?
by Andrew Wallis 07 May '02

07 May '02

I have a shell script which runs an expect script which, in turn, connects to my router and reboots it. I've had something very like it for ages but I've had a problem ever since a recent upgrade to RH7.2. Basically, the script works fine in the foreground; it works fine under "at now +1 minute"; it works fine under "batch" BUT it always fails when run under cron. The relevant output from failed jobs looks like: ---------------------------------------------------------------------- spawn telnet my-router Trying 192.168.0.254... Connected to my-router. Escape character is '^]'. Password: Connection closed by foreign host. send: spawn id exp3 not open while executing "exp_send -s -- $arg" (procedure "send" line 3) invoked from within "send -- "X"" (file "/usr/local/sbin/reboot_router.exp" line 53) ---------------------------------------------------------------------- which seems to show that the telnet session is spawned OK and opens the connection (the "Password: " string comes from the router) but then as soon as expect tries to send the first character of the password, it finds that the telnet session has been closed! Any ideas, please? PS. Yes, I know all of the security risks in embedding passwords in scripts and in using telnet rather than ssh!
