[CLUG] Shell script newbie

[Jean-Pierre Thibert]

Hi everybody and happy new year,

I'm learning shell script and have some questions. Could you help me?

1)I have a variable with a value between 00.00 to 100.00 (ie : 12.58)
I want to extract the integer. Something like X=int(MYVAR)
How to do that? I didn't find out after a lot of research.

2) I think wget command has an output only as a file not a variable.
Am I right?

3) I tried to find a script commands reference on Internet and a 
detailed training unsuccessfully.
Have you some good links?

Thank you for your help
