I need to unistall expose.sh on Linux - webhooks

I installed the expose.sh webhook service by mistake. Now I need to uninstall it, as it doesn't work for laravel projects I have a Linux Mint operating system. I've tried
sudo apt remove expose.sh
and
composer remove expose.sh
but neither works.

wget command not found on linux server

I have a linux server (completely new, web hosting, nothing is installed into it), and want to use a "wget" command. Currently, it is not found. Kernel version 2.6.32-896.16.1.lve1.4.54.el6.x86_64
I am completely new to linux, tried to solve this issue by myself, but couldn't do it. I log in into this linux server via PuTTY via my Windows OS laptop.
wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
To get "wget" to work, I will need to install it. I guess I will need to install first "sudo" and/or "apt" and/or "apt-get". But couldn't do it. Please give me a short list of steps in which order to install them.
Given your kernel version, it looks like your Linux distribution is CentOS 6 or RHEL 6. Try installing wget with this command:
yum install wget
You must be root when you run this command.
Incase you using Debian version of Linux, use the following:
sudo apt-get install wget
From kernel version, it looks like you are using RHEL/Centos 6.
Please check -
https://centos.pkgs.org/6/centos-x86_64/wget-1.12-10.el6.x86_64.rpm.html
If the mentioned dependencies exist in your system, you can directly fire the rpm command
rpm command guide -
https://docs.fedoraproject.org/ro/Fedora_Draft_Documentation/0.1/html/RPM_Guide/ch02s03.html
If it doesn't work, you need to use yum command. (You need to configure yum command first, if not configured already)
yum install wget
To configure yum command in centos6 -

Note - you need to be root user for above activities.

Install package managers over SSH & FTP

i have an device running on Pure Linux, there is no Package installer installed on that, the only thing i have is SSH and therefore also an Terminal. Commands like apt-get, dpkg, yum dont work.
How do i install apt-get over SSH? I've saw some suggestions that use yum, make or dpkg to install apt-get, but since i've neither of them...
For debian based systems exists a tool called apt-offline. That's perfect in that scenario.

Reset Realm Object Server on Linux

Can I ask that are there any scripts in Linux that similar to reset-server-realms.command on Mac that can delete all realms on server. Actually I need to reset the server and clean it before use the application officially. I try to uninstall regarding to the guides on Realm website but somehow the old data still comes up.
Thanks
Uninstalling the package doesn't remove any data. This is done on purpose, so that the upgrade process of RPMs and debs works properly.
We don't provide a script, but the easiest way to wipe everything is simply to run:
sudo rm -rf /var/lib/realm
# CentOS
sudo yum remove realm-object-server-de
sudo yum install realm-object-server-de
# Ubuntu
sudo apt-get install --reinstall realm-object-server-de
Please note that this will preserve your configuration, still. The configuration is stored in /etc/realm.

Linux: Console apt-get not available?

I need to install Java, Solr, and update Git on this dedicated server.
I have ssh root access and was going to use the apt-get method to install what I need. But says this command is not found. Is this not a core Linux thing? I am guess I need to now look into installing this before doing anything else?
I don't have CPanel access.
This is solved. I did not know there was a different package manager with CentOS and Ubuntu. I used yum and it worked. I will mark this answered once I am able.

How do I remove Xen from Ubuntu?

I was trying to install VM software on my Ubuntu system. Since I'm not very familiar with linux I followed a guide on the official Ubuntu site. Now I am running Ubuntu in a Xen environment, but I don't want to use Xen to make my virtual machines.
I installed Virtualbox in order to create my VM's, but Virtualbox doesn't run in a Xen environment.
I have tried googling for a way to remove Xen from my system, but I am unable to do it. This is what I've tried so far:
Editing /boot/grub/grub.cfg set default="Xen 4.1-amd64" to set default=1 which was recommended by a tutorial. It made my laptop start up in recovery mode and I had to generate a new grub config file which put the default back to xen.
Editing /boot/grub/menu.lst but I don't have any files called that on my system
user#BEL-8WF4XW1:~$ sudo find / -name menu.lst
user#BEL-8WF4XW1:~$
Looking through software center, but I couldn't find anything about Xen
The command make uninstall but I didn't use the source code.
I also tried to install yum and do sudo yum install kernel followed by sudo yum remove xen kernel-xen libvirt but that also didn't work.
I'm quite lost to be honest. Can anyone help me to get my Ubuntu back to how it was before I tried to follow that guide?
I'm no expert but I've executed
sudo apt-get purge xen*
and it worked for me.
You can just try
sudo apt-get remove xen-hypervisor-amd64
or
dpkg -i xen-hypervisor-amd64
to see which xen files have been installed in your machine
