Hi all,
I'm bit new to the advanced bash shell scripting.
When I'm looking at some of the existing code in my organization, got confused with a few variable definings.
For ex:
var1={1:-30}
var2="abc def ghi"
var3={xyz:-$var2}
In above, 1st and last lines are confusing me. Could anyone explain the meaning of it and how we can use those variable values please?
It would be very helpful if anyone suggest a brief guide or doc about advanced bash shell scripting.
Thnaks in advance.
