Question

With first 9 arguments being referred from $1-$9, $10 gets interpreted as $1 followed by a 0. How do I account for this and access arguments to functions greater than 10?

Thanks.

Use :

#!/bin/bash
echo ${10}

To test the difference with $10, code in foo.sh :

#!/bin/bash
echo $10
echo ${10}

Then :

$ ./foo.sh first 2 3 4 5 6 7 8 9 10
first0
10

the same thing is true if you have :

foobar=42
foo=FOO
echo $foobar # echoes 42
echo ${foo}bar # echoes FOObar

Use {} when you want to remove ambiguities …
