Assign script parameters to variables

giorgos193 · #1 (**permalink**) 04-14-2008

Hi,

I have a bash script that accepts some parameters as input, like:

sh script.sh first second third .....

I want to save these parameters as different variables, something like:
VAR1=first
VAR2=second
etc

I tried this, but apparently it didn't worked....
------------------------------
for ((i=1;i<=$#;i=i+1))
do
VAR${i} = $"${i}"
done
------------------------------

I hope I made myself clear....
Thank you in advance.

Code:

for ((i=1;i<=$#;i++))
do
   eval VAR$i="\$$i"
done

Thanks a lot... It looks to work... but how can I call these different variables?

echo $"VAR$i" (???????)

It's a trivial question, but it would be appreciated if you can help on this...

Thanks again, for your help!

Hmm, you named them in the first place? The first is $VAR1 and so forth.

thanks for the reply!

Yes, obsiously, this could be a way.... but can I, for example, to call them inside the for loop?

Because the number of arguments is not known apriori...

You need another eval for that. The rest should come easily.
