You may already know that PowerShell is a cross-platform command line tool developed by Microsoft that allows you to perform various tasks on Windows, Linux, and macOS. But do you know how to install and use PowerShell on Linux? In this article, we’ll cover how to install PowerShell on different Linux distributions and how to leverage its power to streamline and automate your workflows.
Install PowerShell Core 6.0 on Linux system
To install PowerShell Core 6.0 in Linux, we will use the Microsoft Software Repository, which allows us to install through the most popular Linux package manager tools, such as apt-get, yum, etc.
Installation in Ubuntu 16.04
First, import the GPG key for that public repository, then register the Microsoft Ubuntu repository into the APT source to install PowerShell:
$ curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add - $ curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list | sudo tee /etc/apt/sources.list.d/microsoft.list $ sudo apt-get update $ sudo apt-get install -y powershell
Installation in Ubuntu 14.04
$ curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add - $ curl https://packages.microsoft.com/config/ubuntu/14.04/prod.list | sudo tee /etc/apt/sources.list.d/microsoft.list $ sudo apt-get update $ sudo apt-get install -y powershell
Installation in CentOS 7
First, register the Microsoft RedHat repository into the YUM package manager repository list, and then install PowerShell:
$ sudo curl https://packages.microsoft.com/config/rhel/7/prod.repo > /etc/yum.repos.d/microsoft.repo $ sudo yum install -y powershell
How to use PowerShell Core 6.0 in Linux
In this section, we will briefly introduce PowerShell; we will see how to start PowerShell, run some basic commands, and operate files, directories, and processes. Then learn how to list all available commands, display command help, and aliases.
Enter the following command to start PowerShell:
$PSVersionTable
You can check the PowerShell version with the following command:
$ powershell
Run basic PowerShell commands in Linux:
get-date [# 显示当前日期] get-uptime [# 显示开机时间] get-location [# 显示当前工作目录]
Manipulating files and directories in PowerShell
1. You can create an empty file in two ways:
new-item tecmint.tex 或者 "">tecmint.tex
Then add content to it and view the file content:
set-content tecmint.tex -value "TecMint Linux How Tos Guides" get-content tecmint.tex
2. Delete a file in PowerShell
remove-item tecmint.tex get-content tecmint.tex
3. Create directory:
mkdir tecmint-files cd tecmint-files “”>domains.list ls
4. To perform a long-format list operation and list file/directory details, including mode (file type), last modification time, etc., use the following command:
dir
5. Display all processes in the system:
get-process
6. View the details of the running process/process group by the given name, and pass the process name as a parameter to the above command, as follows:
get-process apache2
The meaning of each part in the output:
- NPM(K) – Non-paged memory used by the process, unit: Kb.
- PM(K) – pageable memory used by the process, unit: Kb.
- WS(K) – The working set size of the process, unit: Kb. The working set consists of the memory pages referenced by the process.
- CPU(s) – The amount of processor time consumed by the process on all processors, in seconds.
- ID – Process ID (PID).
- ProcessName – Process name.
7. To learn more, get the PowerShell command list:
get-command
8. If you want to know how to use a command, check its help (similar to man in Unix/Linux); for example, you can get help for the command Describe like this:
get-help Describe
9. To display the aliases of all commands, enter:
get-alias
10、 最后，不过也很重要，显示命令历史记录（曾运行过的命令的列表）：
history
就是这些了！在这篇文章里，我们展示了如何在 Linux 中安装微软的 PowerShell Core 6.0。在我看来，与传统 Unix／Linux 的 shell 相比，PowerShell 还有很长的路要走。目前看来，PowerShell 还需要在命令行操作机器，更重要的是，编程（写脚本）等方面，提供更好、更多令人激动和富有成效的特性。
