Add bash style commands to the Windows PowerShell
As a developer that spends 99% of my time on Linux, doing things on Windows gets cumbersome trying to remember the PowerShell syntax. Here’s an easy way to add the most common bash commands to the PowerShell.
Create the file ‘bash-style-commands.ps1’ in your $HOME directory. Open PowerShell and copy/paste the following:
New-Item -Path "$HOME\bash-style-commands.ps1" -ItemType "file" -Force
To open the file in notepad:
notepad $HOME/bash-style-commands.ps1
In notepad, paste the following and save.
# Bash-style commands for PowerShell
# Claude 3.7 & Eric Hammond
# Usage: Add '. $HOME\bash-style-commands.ps1' to your PowerShell profile
# Basic Linux commands

notepad $PROFILE
Add this line at the end of your profile file and save:
. $HOME\bash-style-commands.ps1
Restart PowerShell, and you should see:
