Then exits a login shell / ssh session and log back in using the following command:
Open a terminal or log in using ssh:
$ ssh [email protected] Biz
Alternatively, use the following command to source completion code for bash:
$ source /etc/bash_completion
For newer version try:
$ source /etc/profile.
In this article we will show you how to install Zabbix 3. 4 on CentOS 7 and RHEL 7, Zabbix is a free and open source network monitoring Software tool which is used to monitor and track the availability and performance of your IT infrastracture: servers, network devices and other IT assets.
For example, the ls command can be used to display the files and directories in the current working directory:. Commands are entered at the shell command prompt simply by typing the command and pressing the Enter key. Whilst some commands perform tasks silently, most will display some form of output before returning to the prompt.
From within the GNOME desktop environment, the shell prompt may be accessed from a Terminal window either by selecting the Applications -> System Tools -> Terminal menu option or right clicking on the desktop and selecting Open in Terminal from the resulting menu. When remotely logging into a CentOS 6 server, for example using SSH, the user is also presented with a shell prompt. When booting a server based system in which a desktop environment has not been installed, the shell is entered immediately after the user completes the login procedure at the console terminal or remote login session.
Sometimes referred to as TAB completion, this feature permits you to easily. Bash (Bourne Again Shell) is undoubtedly the most popular Linux shell out there, no wonder it is the default shell on many Linux distributions. One of its most charming features is the built-in “auto-completion” support.
在 Linux 的環境下，如果你不懂 bash 是什麼，那麼其他的東西就不用學了！因為前面幾章我們使用終端機下達指令的方式.

You need to use the dnf command:
$ dnf search bash-completion
To get info just run the dnf command with info option:
$ dnf info bash-completion
Now all you have to do is type the following dnf command to install it:
$ sudo dnf install bash-completion.
For the current session use the source command to load it:
$ source /etc/profile. Sh
Press the [TAB] key while typing a command to auto-complete syntax or options:
sudo dnf i[TAB]. The script will get call automatically from your login session or when you start a fresh shell session.
I am trying to get tab-completion working in Yum in CentOS 6 (so I can do something like yum install firefo and get back firefox), and I have found many.
Since we will want to run JBoss as a non-root user with minimal privileges, we'll create a user, jboss, who will own the JBoss files and JBoss will run under his account.
