How do I run multiple commands on one line in PowerShell?


Use a semicolon to chain commands in PowerShell:

ipconfig /release; ipconfig /renew

A semicolon will link the commands as the previous answer stated, although there is a key difference to the behaviour with the & operator in the MS-DOS style command interpreter.

In the command interpreter, the variable substitution takes place when the line is read. This allows some neat possibilities such as swapping variables without an interim:

set a=1
set b=2
set a=%b% & set b=%a%
echo %a%
echo %b%

Would result in:


As far as I know, there is no way to replicate this behaviour in PowerShell. Some may argue that’s a good thing.

There is in fact a way to do this in PowerShell:

$b, $a = $a, $b

It will result in a single line swapping of the variable values.

In PowerShell 7, we have Pipeline chain operators which allows you to add some conditional element to your sequential one-line commands

The operators are:

  • && this will run the second command only if the first one succeeds.
  • || this will run the second command only if the first one fails.


PS Z:Powershell-Scripts> Write-Host "This will succeed" && Write-Host "So this will run too"
This will succeed
So this will run too

PS Z:Powershell-Scripts> Write-Error "This is an error" && Write-Host "So this shouldn't run"
Write-Error "This is an error" && Write-Host "So this shouldn't run": This is an error

PS Z:Powershell-Scripts> Write-Host "This will succeed" || Write-Host "This won't run"
This will succeed

PS Z:Powershell-Scripts> Write-Error "This is an error" || Write-Host "That's why this runs"
Write-Error "This is an error" || Write-Host "That's why this runs": This is an error
That's why this runs

of course you can chain them even more together like x && y || z etc.

this also works for old cmd-like commands like ipconfig

PS Z:Powershell-Scripts> ipconfig && Write-Error "abc" || ipconfig


Ethernet-Adapter Ethernet:

   Verbindungsspezifisches DNS-Suffix: xxx

   IPv4-Adresse  . . . . . . . . . . : xxx
   Subnetzmaske  . . . . . . . . . . :
   Standardgateway . . . . . . . . . : xxx
ipconfig && Write-Error "abc" || ipconfig: abc


Ethernet-Adapter Ethernet:

   Verbindungsspezifisches DNS-Suffix: xxx
   Verbindungslokale IPv6-Adresse  . : xxx
   IPv4-Adresse  . . . . . . . . . . : xxx
   Subnetzmaske  . . . . . . . . . . :
   Standardgateway . . . . . . . . . : xxx

These operators use the $? and $LASTEXITCODE variables to determine if
a pipeline failed. This allows you to use them with native commands
and not just with cmdlets or functions.
