    file not found during running a script

    I'd agree that it's likely a permissions or a path issue.. does the script assume paths or are they typed out pretty well?

    Installation of Kali Linux 2019.3

    Hey Griyan, He's hinting that you're probably not ready for Kali unless you have the experience in Linux to be able to troubleshoot some things.. or know that you'd need to post more information than "installation failed" in a forum to get some assistance with it. You'd want to post some...

    mounting NAS on CentOS 6.1

    I'd let it error out and see what you can get from it. See if it times out or whatever. Also, maybe look in /var/log/messages to see if there's any hints.. maybe even typing dmesg to see if there's anything

    How do I run the Scripts in the Startup

    Hey there - I've done this on a couple servers in the past. You can put a line in your crontab that starts with @reboot and it should run each time the machine is started up - or rebooted. Like: @reboot /path/to/your/script

    @Matthew1974 - welcome to the forum! sudo can get very granular, for instance you can add a user to sudoers and allow him to do anything, or limit them to just one (or a few commands). Here's a short video...
