Script to monitor a certain amount of files in a directory in bash

Question

I'm breaking my head with a simple script and I need help.

I have the following scenario:

I have a directory to monitor where the script will run until the number of files reaches the expected number (exit 0) or the expiration time arrives (exit 1)

---

Rules:

1. Number of files hit, exit 0
2. Time limit hit even without the amount of files reached, exit 0

Usage: ./filemonitor.sh <file_mask> <file_amount> <expire_time>

Eg: ./filemonitor.sh /home/abc/ dl*.txt 5 14

I don't know if I made myself clear but what am I doing wrong?

Script

#!/bin/bash

# Variables
now=$(date +"%H")

# User input
files_path=$1
files_msk=$2
files_qtde=$3
files_lmttime=$4

check() {

    while :; do

        file_count=$(find $files_path -mindepth 1 -maxdepth 1 -type f -iname "$files_msk" | wc -l)

        if [ $file_count -lt $files_qtde ]; then

            if [ $now -ge $files_lmttime ]; then

                echo 'Time is over!'
                exit 1

            elif [ $now -lt $files_lmttime ]; then

                echo 'On time, process running'
                echo 'Wait 5 secs'
                sleep 5

            fi

        elif [ $file_count -eq $files_qtde ]; then

            echo "file count="$file_count "file expected="$files_qtde
            echo 'Files OK'
            exit 0

        fi

    done
}

Problem solved. Thanks for all.
