Custom scripts and aliases that you can adapt to your own needs.
Introduction
Thanks for downloading the EzeeLinux BASH Script Collection! These
are scripts that I use on a daily basis and they've been discussed in YouTube videos and Facebook posts. You guys have asked for them and now they are all available in one happy .zip file. I will offer a brief explanation of each one here. Be aware that some will need to be edited to fit your specific needs. For instance, SyncIt is an automated script that uses rsync to sync data between machines on my network and it has directories listed that are peculiar to my setup. To use it on your system, you will have to setup static IP addresses, install and configure SSH to work with security keys and not passwords and you will have to substitute your own directories. All of these are designed to work with Ubuntu based Linux. They should work just fine with Linux Mint or any other distribution based on Ubuntu. They may or may not work with other distributions and I have not been tested on
BASH scripts don't require installation. All you need to do is
create a directory in your home directory called "bin" (must be lowercase) and then you may have to log out and log back in to get the system to see it. Any executable file placed in your personal bin directory can then be run by typing its name, just like any other command, at a terminal. Make sure the script is executable in a File Manager and it's ready to use. Keep in mind that scripts in your bin will not be seen by the system if you issue them with sudo. The system will prompt you if sudo privileges are required.
The Scripts
Here is a list of the scripts and a bit about what they do:
chksys
This script give you vital system information. I wrote it to quickly
check on the status of my server.
nr
This alias restarts Network Manager in Ubuntu and Linux Mint. It can be
useful if you're working on a bad wi-fi network and you need to reestablish a connection.
SFTPin and SSHin
These are small scripts that can also be set as aliases or functions
in your .bashrc file. They work with SSH and make logging into machines on your network super easy. You must know the IPv4 address of the machine you wish to log into and the script assumes that your LAN is using a subnet that uses 192.168.0.xx with the x's standing for the specific machine number. Different routers use different schemes so you may have to change that. The "$1" represents a variable that contains the first argument after the command. So, you would simply type 'sshin 12' to log into a machine on your LAN that has the address 192.168.0.12. The command 'sftpin 12' would open the SFTP file transfer program and you can use it to move move file from one machine to another just as you would use a public FTP server.
SyncIt
This script also works with SSH and let's you sync directories
across a network. The rsync command used here will make an exact copy of whatever is in the local machine's directories on a remote machine. Files that have changed or have been added to the local machine will be copied or updated on the remote machine. Files that have been deleted locally will be removed from the remote host, as well. WARNING! This script will also remove files that are on a remote machine that do not exist in the local machine you're sending from! It makes an exact copy of whatever is in the directory being synced so if you have files on the remote machine you want to keep that it's not a good idea to run SyncIt before using SFTPin to grab those remote files and make sure they are on the local machine first! The directories in the script are the ones I have chosen to sync but a bit of editing will make it work for you. Make sure that all the IP addresses match your network scheme. Just as in the scripts above, the way to issue a SyncIt command is: 'syncit 12' We're assuming here that the machine you're wanting to sync to has the IP address 192.168.0.12.
Syncall
Runs syncit for all the machines on the network. This script will require
you to customize it for your own network.
rbu
This is a simplified version of BU that is intended to run on a remote
machine through SSH. You must manually mount the BU_Drive before running this script.
firefox-purge.sh
This script removes the Firefox browser and replaces it with Google CHrome.
It works on Debian and Ubuntu based systems.
Ubuntu Installation Scripts
These are scripts that automate setting up Ubuntu for my Dell workstation.
They are highly customized to my needs. You can use them as a springboard to create your own installation scripts.
oldkernrm
This script is for CentOS. It will automatically remove all old kernels.
I use it as a clean-up tool for my server.
ocenaudio-installer.sh
This script installs the Ocenaudio editor. It can also be used to update
the application without having to go to Ocenaudio's web page.
Z-Clean and Z-Defrag
These are Anacron wrapper scripts that work with the Anacron
scheduling system. You use them by copying them to one of three directories on an Ubuntu based system. (Anacron may or may not be configured on other Linux distributions. Check the documentation to find out before adding these scripts.) Those directories are: /etc/cron.daily /etc/cron.weekly /etc/cron/monthly. Any script placed in these directories will run periodically in the background on your machine. They must be written for sh and there is a specific format so be cautious when editing them. Feel free to change the parameters of the commands and also these can be used as templates for commands you'd like to have run automatically. They begin with a Z to ensure that they're the last scripts to run. This way they will not conflict with system scripts that may already be in the Anacron directories. Anacron has several advantages over regular cron and you should take time to read some documentation before you start playing around with it. The manual page is well written and you can access it with the 'man anacron' command in a terminal.
Conclusion
Have fun with these! Feel free to do with them as you will but keep
in mind that I have not tested them on every other Linux distribution available and I cannot offer support to you if they don't work on yours. I would love to hear your comments and I will happily look at any suggestions for new features or code fixes but I do not have the time or inclination to run and test your modified versions, act as a beta tester or even offer useful advice if your changes are not working. I am NOT an expert; I am simply sharing tools that I use everyday.
