Store Header Transcript For Free

The transcript more or less echoes the PowerShell window's contents. You can see the command prompt, as well as the command that was entered. You can also see the command output if output exists. Having this information makes it a lot easier to see exactly what was done during a PowerShell session.

The Start-Transcript cmdlet creates a record of all or part of a PowerShell session to a text file. The transcript includes all command that the user types and all output that appears on the console.

$PSScriptRoot is the Root Path of where the current script is saved. When used in a command it will return blank as there is no script who's current path you are looking for.

To log everything that would normally be written to the console, like -verbose you can use Start-Transcript and when you are finished Stop-Transcript .

You can either start the transcript in your PowerShell session or include it in your script. Without any parameters, the transcript will be saved in the user's documents folder. The filename will automatically be generated and consists of the device name, random characters followed by a timestamp.

$PSScriptRoot Contains the full path of the executing script's parent directory. In PowerShell 2.0, this variable is valid only in script modules ( . psm1 ). Beginning in PowerShell 3.0, it's valid in all scripts.

The $PSScriptRoot automatic variable is $null if used from outside a PowerShell code file. If used inside a PowerShell script, it automatically defined the fully-qualified filesystem path to the directory that contains the script file. In Windows PowerShell 2.0, this variable is valid only in script modules (. psm1).

The Start-Transcript writes everything in your session when you are run a script in a log file. It's straightforward to use it with a couple of parameters.

If you are writing a Powershell script and want to redirect some output, here is how you can do it. You can either use > , like in a Linux script, or pipe ( | ) the output to a file, with the Out-File cmdlet. It is also possible to redirect it to a null target, effectively suppressing it. The two have the same result.

The Start-Transcript cmdlet writes everything that happens during a session to a log file. These are the commands that you enter in a PowerShell session and all output that normally appears in the console. You can use this during your normal PowerShell session, but it's more useful for creating log files.
