How to Install and Use Microsoft PowerShell on Linux

As Microsoft has made Powershell open source and can be installed and used on different operating system family (Linux and MacOS), Basically Microsoft is working towards new Powershell Core make it available everywhere now and it is cross platform. As I don't have much knowledge on bash scripting, I can use my PowerShell scripting knowledge on Linux to write some scripts for automation. Powershell core can be downloaded from There are different powershell application packages available on github for different OS flavors.

Once downloaded PowerShell rpm file I have used WinSCP tool to copy/transfer rpm file on Linux server. When I list directory where RPM file is stored with ls -l, file name shows in Red. Red color means it can not be executed and installed. To make it executable and modify permissions run command chmod +777 powershell-xxx.rpm, once again I run ls -l, file color shows Green and good to execute run. (I don't have yum repository configured so I am using rpm file)

To install package run command - sudo yum install -y powershell-xxx.rpm. This ask for sudo root password, while installation few lines need to read from onscreen installation logs, there are no dependencies for Powershell, and it is installed successfully.

Next I am using putty to login Linux server (Powershell yellow colored commands are not visible correctly on white background terminal). I can view and verify Powershell rpm is installed successfully using rpm -qa powershell command. Type powershell in the console (case sensitive) to execute powershell, but in my case it shows error as bash: powershell: command not found... Instead use pwsh command. and try normal cmdlets (ie: Get-Process, Get-Command) to check it is working as expected.

Command exit will close powershell and come back to bash shell. I am not master on Linux, but I do normal troubleshooting very well, here I can add alias powershell to pwsh in /etc/profile using command echo 'alias powershell='pwsh'' >> /etc/profile. next time I can execute powershell by running powershell only.

When Powershell is installed on Linux it is located under default path /opt/microsoft /powershell/6.xxxxx/. Next verify powershell version using command $PSVersionTable.

Note: If you see any message or dependency error, make sure you have active internet for download so by default it downloads required rpm from internet. In case if if you don't have internet setup repo or I found one of the dependency libunwind on centos 7 minimum installation and downloaded and installed it separately from
