We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

puppetlabs/pwshlib — version 1.1.1 Feb 21st 2024


Code Owners ci GitHub release (latest by date)

The PowerShell gem.

This gem enables you to execute PowerShell from within ruby without having to instantiate and tear down a PowerShell process for each command called. It supports Windows PowerShell as well as PowerShell Core (and, soon, just PowerShell) - if you're running *PowerShell v3+, this gem supports you.

The Manager class enables you to execute and interoperate with PowerShell from within ruby, leveraging the strengths of both languages as needed.


Add this line to your application's Gemfile:

gem 'ruby-pwsh'

And then execute:

bundle install

Or install it yourself as:

gem install ruby-pwsh


Instantiating the manager can be done using some defaults:

# Instantiate the manager for Windows PowerShell, using the default path and arguments
# Note that this takes a few seconds to instantiate.
posh = Pwsh::Manager.instance(Pwsh::Manager.powershell_path, Pwsh::Manager.powershell_args)
# If you try to create another manager with the same arguments it will reuse the existing one.
ps = Pwsh::Manager.instance(Pwsh::Manager.powershell_path, Pwsh::Manager.powershell_args)
# Note that this time the return is very fast.
# We can also use the defaults for PowerShell Core, though these only work if PowerShell is
# installed to the default paths - if it is installed anywhere else, you'll need to specify
# the full path to the pwsh executable.
pwsh = Pwsh::Manager.instance(Pwsh::Manager.pwsh_path, Pwsh::Manager.pwsh_args)

Execution can be done with relatively little additional work - pass the command string you want executed:

# Instantiate the Manager:
posh = Pwsh::Manager.instance(Pwsh::Manager.powershell_path, Pwsh::Manager.powershell_args)
# Pretty print the output of `$PSVersionTable` to validate the version of PowerShell running
# Note that the output is a hash with a few different keys, including stdout.
# Lets reduce the noise a little and retrieve just the version number:
# Note: We cast to a string because PSVersion is actually a Version object.
# We could store this output to a ruby variable if we wanted, for further use:
ps_version = posh.execute('[String]$PSVersionTable.PSVersion')[:stdout].strip
pp("The PowerShell version of the currently running Manager is #{ps_version}")
