Linux Shell Scripting Cookbook

[bitsnpcs]

This is the result when using the ` instead of the '



This is the result not using ` or ' as per my playing with it, (the second running of the file in the terminal, the first is from the above version), the result it is how the book says it should look.




[member=7109]Moltke[/member] you are correct, Copying/Pasting from the book or typing it in to the command line does produce 81.0.
It just fails when used as a script that is a file and I am still not sure why that is.

I will edit my earlier post about there being an error in the book.

I'll give this book a miss, I'll stick with the books at home for now.
I may try this book again once I have more experience and can follow it better.

I may even need the book [member=7701]kpanic[/member] described to me "And a child can learn it (with the time they use inall those 'social media' sites)."
I can understand that eg; when learning a new language it is often that you use childrens books in the new language for the first books you read.
