Install zsh-autosuggestions&zsh-syntax-highlighting to Oh-my-zsh plugins.

Ather install Oh-my-zsh

If you havn't git in your Linux, you can:

$ sudo apt install git //Ubuntu

$ sudo yum install git //CentOS

Use git clone method

$ git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

Keep ssh connection alive

Here is the solution to keep the terminal ssh status alive

If you don't know where the file you should change, you can:

$ find / -name "ssh_config" it will tell where is it, such as /etc/ssh/sshd_config

change the default config

$ sudo vim /etc/ssh/sshd_config and find

Change Linux Timezone

Use `date -R` to display system time

Sometime the linux will use 0 timezone, so we need to change.

Type this:

$ timedatectl list-timezones

Change Hostname in CentOS or Ubuntu

I choose the manual way

type this to display current hostname:

hostname

and type this to change it:

sudo hostnamectl set-hostname NewName

Turn on the Google BBR on CentOS8

there is an easy way if you have kernel version above 4.9.0 type this to display the current version: uname -R

Just three steps to turn on BBR

Line by line to input:

echo 'net.core.default_qdisc=fq' | sudo tee -a /etc/sysctl.conf

Fixed chsh: command not found in CentOS 8

This problem happens on some vps provider.

Need to manual install to solve it

sudo dnf install util-linux-user

That means use dnf to solve it.

Change SSH port on CentOS 8

The key step is to turn your want listen-port and close the default ssh-port. For CentOS 8, will use firewalld

Open your want listen-port and close the default

sudo firewall-cmd --zone=public --permanent --add-port=30000/tcp
sudo firewall-cmd --zone=public --permanent --remove-service=ssh

If firewalld not installed, you can manually install and enable it.

Locations of Ubuntu's desktop shortcut

They will be on these three locations:

/usr/share/applications
/usr/local/share/applications
~/.local/share/applications

Normally, for not root user, it will be at the home directory, that mean is~/.local.
