Most people who quit the terminal in week one quit because they copied a command off the internet, it failed, and they figured they were the problem. They weren't. They were on Windows running a Linux command. The commands are different. That was all it ever was. Here's the one that does the most damage. On Mac or Linux you list files one per line with "ls -1". Run that same thing in PowerShell and you get this: Get-ChildItem: Cannot find path 'D:\Office-Agent\-1' because it does not exist. Read it again. It's complaining about a folder you never typed. PowerShell took the "-1" and read it as the name of the place you wanted to look in. Nothing in that message tells you the flag was the problem, so you sit there staring at a path that doesn't exist wondering what you broke. The ones that catch people most often: ls -1 -> Get-ChildItem -Name ls -la -> Get-ChildItem -Force cat file -> Get-Content file head -n 10 file -> Get-Content file -TotalCount 10 tail -n 10 file -> Get-Content file -Tail 10 tail -f file -> Get-Content file -Wait grep "error" app.log -> Select-String -Path app.log -Pattern "error" find . -name "*.txt" -> Get-ChildItem -Recurse -Filter *.txt which git -> (Get-Command git).Source touch a.txt -> New-Item -ItemType File a.txt mkdir -p a/b -> New-Item -ItemType Directory -Force a/b rm -rf old/ -> Remove-Item -Recurse -Force old export KEY=abc -> $env:KEY = "abc" echo $PATH -> $env:PATH cmd 2>/dev/null -> cmd 2>$null One more worth knowing. The && that chains two commands together works in PowerShell 7 and up, but it's a syntax error on the older Windows PowerShell 5.1 that ships with Windows. Check yours with $PSVersionTable.PSVersion. If it starts with a 5, install PowerShell 7. It sits alongside the old one, it doesn't replace it. The rule that saves you the most time: when something fails, read the error before you retype anything. "The term X is not recognized" means the command doesn't exist on Windows at all. "A parameter cannot be found" means the command is right and the flag is wrong. Those two sentences cover most of what goes wrong in your first month.
