Question

For a program I am writing, I need to read a value from a file. When I do that, I get a value in the form (x, y). I need to make a script that splits those, so $x is the x value and $y is the y value.

Then, I need to do a check. For example, check if $x is in between $x-max and $x-min, with $x-max and $x-min being integers.

Answer 1

To split the string into two numbers:

$ foo="(506,-664)"
$ declare -a bar=${foo//,/ }
$ for integer in ${bar[@]}
> do
>     echo "$integer"
> done
506
-664
