| Write a PowerShell 7 Core script that lists installed WSL distributions in a nicely formatted table, including: | ||
| Write a PowerShell 7 Core script that lists installed WSL distributions in a table. | ||
|
|
||
| - The distribution name, listed under the heading "Distribution Name" | ||
| - The distribution's default UID, by reading the default UiD key, listed under the heading "Default UID" | ||
| The table should show: | ||
|
|
||
| - Whether the distribution is the default distribution, by reading the DafaultDistribution key at HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Lxss. If the distribution name matches the DefaultDistribution key, then the distribution is the default distribution, display an asterisk (*) next to the distribution name. If the distribution is not the default distribution, then do not display an asterisk next to the distribution name. | ||
| - The distribution name from the Windows Registry, listed under the heading "WSL Distro Name" | ||
| - The distribution PRETTY_NAME, by spawning a process in that respective distribution and reading the distribution's /etc/os-release file for PRETTY_NAME, listed under the heading "Linux Distro Name" | ||
| - The distribution's version, by spawning a process in that respective distribution and reading the distribution's /etc/os-release file for VERSION, listed under the heading "Distro Version" | ||
| - Whether the distribution has systemd enabled or not, by spawning a process in that respective distribution and reading /etc/wsl.conf for the systemd=true key, listed under the heading "systemd" | ||
| - The distribution's default UID, by reading the default UiD key in the Windows Registry, listed under the heading "Default UID" | ||
| - The distribution's default username, by spawning a process in that respective distribution, running "id -un -- " followed by the default UID key in the respective WSL distribution, and parsing the output, under the heading "Default User" | ||
| - The distribution's state, by reading the State key, and listing "Installed" for a value of 0x1, "Installing" for a value of 0x3, or "Uninstalling", for a value of 0x4, under the heading "State" | ||
| - The distribution's WSL version as 1 or 2, by reading the Version key, listed under the heading "Version" | ||
| - The distribution's state, by reading the State key in the Windows Registry, and listing "Installed" for a value of 0x1, "Installing" for a value of 0x3, or "Uninstalling", for a value of 0x4, under the heading "State" | ||
| - The distribution's WSL version as 1 or 2, by reading the Version key in the Windows Registry, listed under the heading "WSL Version" | ||
|
|
||
| Additionallly: | ||
|
|
||
| Do not check for, display the default username, or default username header if the optional flag --skip-username is passed to the script. | ||
| - Do not display the distro GUID in the table. | ||
| - Do not create a column for default distro, simply append an asterix next to the default distro's name. | ||
| - Do not use \\wsl$\ to access the /etc/os-release file or /etc/wsl.conf file. | ||
| - Get the /etc/os-release and /etc/wsl.conf files through \AppData\Local\Packages, get them by spawning a process with wsl.exe -d followed by the distribution name then cat each file and parse the output. | ||
| - If /etc/wsl.conf is not found, then the distribution does not have systemd enabled. | ||
| - Do not check for, display the default username, or default username header if the optional flag --skip-username is passed to the script. |
