Hi,

You are using a loop that is never exited, no matter what the input.
Also, there is a difference between a string comparison and a numerical comparison.
A case statement can only match patterns. Like @jgt mentioned, in that syntax a pattern like [50-59] will match a single character, in this case when it is 5, 0-5 or 9.

The [ ... ] syntax does not allows for the use of || within the brackets.

You would need to use
Code:
if [ condition1 ] || [ condition2 ]; then

For numerical comparisons keywords like -eq, -lt, -le and such are used (see man test)




--
Note: Be careful with spaces < = is not the same as <=
