Assign script parameters to variables
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.

Hammer & Screwdriver Real-world programming example
This is from the beginning of one of my scripts to find a zip file within a folder, and process the work for the job. This example has three parameters, and errors when it does not see three.

Code:
# verify correct number of parameters
if [ "$#" -ne 3 ]
   then
      echo "Incorrect number of arguments"
      echo "command jobnum zipfile fileloc -- examples are"
      echo "pcs211fid 51248 myzip.zip drop1  (assumes raw folder inside)"
      echo "pcs211fid 51248 myzip.zip raw"
      echo " "
      exit
fi

# read the parameters
jobn="$1"
zipf="$2"
locf="$3"
echo "Beginning process on job" $jobn "with zipfile" $zipf

Your last comment about not knowing how many variables... then they do not match up to specific functions as in my example? Are they a list of items to process against? I cannot imagine a realworld example of what you describe - thus cannot show sample code.
