Title: bash shell programming
Post by: voidmain on 18 December 2002, 11:15

Was playing around with tput in scripts tonight and thought somebody else may be interested in doing some text screen manipulation. Rather than using the tput command you can also use ANSI sequences, tput would be more portable on all the different terminal types but using echo and ANSI strings is a lot more efficient if your terminal is ANSI capable. Here's a simple little example I just created using ANSI:

http://voidmain.kicks-ass.net/files/c2f2c.ksh (http://voidmain.kicks-ass.net/files/c2f2c.ksh)

tput ???

never used it.  I cut and pasted your code from mozilla into gvim no problems at all.

I cleaned it up a little more and did a floating point version in ksh:

got to love ksh eh!

one little problem...when I enter 33 deg Centagrade it calculates to 297 deg Farenheight

33C is a nice warm summer day in southers Ontario..ok I know Texas is hot but 279...hmm

ps is that ksh93 of pdksh

That's odd, when I run it it calculates to: 91.40F

pdksh must be f00ked up. It works fine with the "real" ksh93. Can you do floating point at all with pdksh? Maybe that's why I ditched it for the real one.

Yep, just confirmed it. pdksh is brain dead and doesn't support floating point math. Get the real one. There is an RPM for it:

ftp://ftp.rpmfind.net/linux/contrib/libc6/i386/ksh93-2000.10.31.0-1.i386.rpm (http://ftp://ftp.rpmfind.net/linux/contrib/libc6/i386/ksh93-2000.10.31.0-1.i386.rpm)

In Canadian English it is "colour"

he meant you spelt the word "standard" wrong, take a closer look.
