Question Help Running a Check in Bash Script
Hey guys, so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.
Code:
unknown-hacker|544> count.sh 1 3
1
2
3

My problem is I want to make it so that if you input invalid parameters, such as non-numerical characters, more than 2 numbers, etc., you'd get an error message. Any suggestions? Thanks in advance.

Edit: Here's what my script looks like so far:
Code:
#!/bin/bash

declare -i INDEX
declare -i RESULTS
if [ $1 -gt $2 ]; then
    INDEX=$1
    while [[ $INDEX -gt $2 ]] || [[ $INDEX -eq $2 ]]; do
        echo $INDEX
        INDEX=$INDEX-1
    done
elif [ $1 -le $2 ]; then
    INDEX=$1
    while [[ $INDEX -le $2 ]] || [[ $INDEX -eq $2 ]]; do
        echo $INDEX
        INDEX=$INDEX+1
    done
else
    echo $1
