BASH if conditions

Question

Hi, I did ask a question before. The answer made sense, but I could never get it to work. And now I gotta get it working. But I cannot figure out BASH's if statements. What am I doing wrong below:

START_TIME=9
STOP_TIME=17
HOUR=$((`date +"%k"`))
if [[ "$HOUR" -ge "9" ]] && [[ "$HOUR" -le "17" ]] && [[ "$2" != "-force" ]] ; then
    echo "Cannot run this script without -force at this time"
    exit 1
fi

The idea is that I don't want this script to continue executing, unless forced to, during hours of 9am to 5pm. But it will always evaluate the condition to true and thus won't allow me to run the script.

./script.sh [action] (-force)

Thx

Edit: The output of set -x:

$ ./test2.sh restart
+ START_TIME=9
+ STOP_TIME=17
++ date +%k
+ HOUR=11
+ [[ 11 -ge 9 ]]
+ [[ 11 -le 17 ]]
+ [[ '' != \-\f\o\r\c\e ]]
+ echo 'Cannot run this script without -force at this time'
Cannot run this script without -force at this time
+ exit 1

and then with -force

$ ./test2.sh restart -force
+ START_TIME=9
+ STOP_TIME=17
++ date +%k
+ HOUR=11
+ [[ 11 -ge 9 ]]
+ [[ 11 -le 17 ]]
+ [[ '' != \-\f\o\r\c\e ]]
+ echo 'Cannot run this script without -force at this time'
Cannot run this script without -force at this time
+ exit 1

Answer 1

#!/bin/bash
START_TIME=9
STOP_TIME=17
HOUR=$(date +"%k")
if (( $HOUR >= $START_TIME && $HOUR <= $STOP_TIME )) && [[ "$2" != "-force" ]] ; then
    echo "Cannot run this script without -force at this time"
    exit 1
fi

Answer 2

Use -a instead of &&:

if [ $HOUR -ge $START_TIME -a $HOUR -le $STOP_TIME -a "_$2" != "_-force" ]; then
    echo "Cannot run without -force at this hour"
    exit 1
fi
