What is PowerShell?
|
|
-------------------
|
|
PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language.
|
|
* it's **cross-platform**: available for Linux, Mac OS and Windows
|
|
* it's **powerful**: fully control your computer
|
|
* it's **open-source**: see the Github repository at https://github.com/PowerShell/PowerShell
|
|
* it's **easy to learn**: see the tutorial at https://www.guru99.com/powershell-tutorial.html
|
|
* it's **fully documented**: see the official docs at https://docs.microsoft.com/en-us/powershell/
|
|
|
|
How to get PowerShell?
|
|
----------------------
|
|
* **Windows 7 and newer** do provide PowerShell by default. It's recommended to install **Windows Terminal** (see the Microsoft Store at https://www.aka.ms/terminal) for a comfortable command-line usage.
|
|
* **On CentOS, Debian, Docker, Fedora, macOS, openSUSE, Red Hat, Ubuntu** visit https://github.com/PowerShell/PowerShell for installation.
|
|
|
|
Afterward, install CUPS by clicking on the green "Code" button or execute:
|
|
```
|
|
$ git clone https://github.com/fleschutz/PowerShell
|
|
```
|
|
|
|
Configure PowerShell as Default Shell
|
|
-------------------------------------
|
|
* **Linux:** make sure PowerShell is installed, then execute: `chsh -s /snap/bin/powershell <username>`
|
|
* **Windows:** no need to, PowerShell is the default shell
|
|
|
|
|
|
Adding Subfolder Scripts/ to the Search Path for Command-line Usage
|
|
-------------------------------------------------------------------
|
|
* **Bash or sh:** edit .profile in your home directory and add the line: PATH="$PATH:/path/to/PowerShell/Scripts"
|
|
* **Windows:** open the environment variables dialogue and add the full path to Scripts/ to the system environment variable "Path"
|
|
|
|
|
|
Using PowerShell in Windows Context Menus
|
|
------------------------------------------
|
|
* to enable "right-click > New > Windows PowerShell Script" just execute Context_Menus/add_ps1_to_New_context_menu.reg
|
|
* to disable it just execute Context_Menus/remove_ps1_from_New_context_menu.reg
|
|
|
|
Script Conventions
|
|
------------------
|
|
Each PowerShell script should follow the 7 golden rules:
|
|
|
|
* **Rule 1:** the filename should be named `<verb>-<object>.ps1`
|
|
* **Rule 2:** to support PowerShell on Linux the first line reads: #!/snap/bin/powershell
|
|
* **Rule 3:** to support PowerShell on Linux the script has execute file permissions (chmod a+rx <file>)
|
|
* **Rule 4:** add a metadata header containing the syntax, description, author, source, and license
|
|
* **Rule 5:** prefer command-line options, but may ask the user in case no option is given
|
|
* **Rule 6:** the encoding of the script is in UTF-8 with BOM to support Unicode characters
|
|
* **Rule 7:** exit 0 for success, else print an error message and exit with the error code (mostly 1)
