Bash cheat-sheet for PowerShell devs Coming from years of Windows dev experience to using a Bash shell took a while to know some of the differences between the two. Since I often still run into these things, I thought it would help me and perhaps other people as well if I wrote some of it down.

Bash to PowerShell Cheat Sheet. Posted by 2 years ago. Bash to PowerShell Cheat Sheet. I am pretty comfortable with Bash and want to do. Sometimes, you want to access shortcuts, su, nano and autocomplete in a partially tty shell. ⚠️ OhMyZSH might break this trick, a simple sh is recommended. The main problem here is that zsh doesn't handle the stty command the same way bash or sh does.
Foreward
I haven't located a good cheat sheet for basic PowerShell commands to manage your Network Card/IP stack, so I thought I should make one. If you like this please share it with your mom because I'm sure she's been waiting to set a static IP address via PowerShell for some time. Also you should call her more.
Assumptions
- Windows 2012/Windows 8 or higher
- Administrator access to the machine in question
- Powershell ran as administrator on the machine in question
CMDLet List:
Most of the commands used to manipulate IP settings can be found by typing Get-Command -Module NetTCPIP
To find out more about any given command, type Get-Help <cmdlet name>Common Tasks
Here are walkthroughs of some of the more common tasks you may want to perform.
List Network Adapters
Gets a list of all adapters in the machine; you'll need to know your adapter name or index # (both listed) for some of the commands below.Change an Adapter Friendly Name
Powershell Command Cheat Sheet Pdf
You may want to consider changing the friendly name of the adapter you intend to manipulate. By giving it shorter, more meaningful name you'll have an easier time going forward. Use the old name you got from the last command. Syntax is Rename-NetAdapter -Name '<Current Name>' -NewName <'New Name'>Get the Current IP Address
Gets all IPv4 addresses on the machine; you'll almost always have multiple as your loopback interface (127.0.0.1) will be listed. Ignore that guy.Powershell Cheat Sheet Pdf
Optionally, you can specify -InterfaceAlias <friendly name> or -InterfaceIndex <index #> to limit the command to a single adapter.
Assign a Static IP Address to your Network Adapter
This command will set the one and only (overwriting what is there) IP address for the specified network adapter. You also can (and should) set the subnet mask with this command. The subnet mask is set via CIDR using the -PrefixLength; see the link for more info about CIDR, but if you're not familiar with CIDR it is likely that you want -PrefixLength 24 which translates to 255.255.255.0 meaning the first three octets are the network while the last is the host. Syntax is New-NetIPAddress -InterfaceAlias <name> -IPAddress <IP address> -PrefixLength <CIDR> -DefaultGateway <Gateway IP> . You can substitute -InterfaceIndex <index #> for -InterfaceAlias .Note: You will get an error if you already have a static IP address with a default gateway. To fix this problem see 'Delete Existing Static IP' below and then try again.
Note2: We're not using 'Set-NetIPAddress' here because it doesn't allow you to set a default gateway. BOOOO.
Set DNS Servers for your Adapter
To look up names you'll need to set DNS server(s). Syntax is Set-DNSClientServerAddress -InterfaceAlias <name> -ServerAddresses ('<IP Address 1','IP Address 2') . You can set as many DNS servers as you like. You can substitute -InterfaceIndex <index #> for -InterfaceAlias .Set a Default Gateway
It's generally easier to set the default gateway as part of the New-NetIPAddress command above, but if you want to set one separately see 'Set a Static Route' below.Delete Existing Static IP (to prep for a new)
This is a two step process; you need to delete the IP, then the gateway. No need to worry about the DNS servers here as it works to overwrite them with the command above. You will need to know the IP address you want to delete first; use get-netipaddress (above) to get it (write it down to use below if necessary). You'll then need to know the NextHop of the gateway. To get this, use the get-netroute command and write down the entry(ies) that have a nexthop of the gateway you intend to remove (see screenshot).The syntax for these commands are
Remove-NetAddress <IPAddress> -Confirm:$False
Remove-NetRoute -NextHop <Gateway IPAddress> -Confirm:$False
Note: If you have multiple routes set with that default gateway it will delete them all. If you haven't manually set routes, don't worry about it (you just have the one).
Set Your Adapter to Use DHCP
This is another two step process; first set the desired adapter IP/Gateway to DHCP then set the DNS servers to pull from DHCP as well.The syntax for these commands are:
Set-NetIPInterface -InterfaceAlias <name> -Dhcp Enabled
Set-DNSClientServerAddress -InterfaceAlias <name> -ResetServerAddress
You can substitute -InterfaceIndex <index #> for -IterfaceAlias if you prefer.
Note: If you have a static gateway set you'll need to perform the second step 'Remove-NetRoute' from the step above as well.
Advanced Tasks
Here are walkthroughs of some of the more common tasks you may want to perform. My assumption here is that you know what you want to do so I won't be discussing the details of what each of these means.
Add/Delete a Static Route
Add: (use -RouteMetric to specify metric or -PolicyStore to control persistence through reboots)Add default route:
Delete: (while this command is very specific you can be more generic; see above)
Test Network Connectivity (Ping)
Test-Connection replaces ping.exe. In addition to the ping functionality Test-Connection supports authentication (if firewall is set accordingly), multiple targets in a single command, running as a job, as well as more detailed returns.Assign a DNS Suffix
This is the domain under which your IP will be registered and under most circumstances will be used to append to hostname searches. Note this is per-adapter. You can substitute InterfaceIndex for InterfaceAlias if you like.Assign an Additional IP Address to your NIC
If you want to add another IP (usually only applicable on a server)References/More Information
