[colug-432] Bash fun

[Tom Hanlon]

Colug...


too funny, every time I post a question I find the answer the moment I  
hit send.

Looks like I want "eval"

Anyhow... any general bash advice in regards to writing good scripts,  
good tutorials, etc.

I was tempted to go with Python because I could use the python  
practice, but I could also use the bash practice.

This will be run on linux, but also open solaris....

Is open solaris fair game for discussion ? How about open solaris with  
bulged capacitors on Motherboard ;-)

So bash open solaris, environment issues.. ?? Are there any I need to  
be aware of.
