Linux crontab 似乎不起作用

Question

I'm trying to use a cron job on linux to back up my minecraft server every 24 hours. The crontab looks like this:

00 00 * * * bash /home/pi/wgsanarchy/backup.sh

And backup.sh looks like this:

#!/bin/sh

var=$(date +"%FORMAT_STRING")
now=$(date +"%d_%m_%Y")

tar -zcvf $now-backup.tar.gz /home/pi/wgsanarchy
gupload $now-backup.tar.gz WGSAnarchy
rm /home/pi/$now-backup.tar.gz

(The gupload line pushes the file to my google drive)

I've tried to change the time so I can see if it works, but so far I don't think it does. Can anyone see any errors?

Thanks!

I do not understand why people undervoting instead of helping each other.

This is a common error in Linux bash script when binaries of tar, gunload and so on are not found at the current directory. To solve the issue, write the PATH variable at the beginning of the bash script. Just execute echo $PATH; in your terminal/bash and copy the result to make PATH variable like this

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin;
