```powershell
Get-Command
Get-Help Get-Command
Get-Help Get-Command -Online
Get-Command New-SmbShare | Select-Object Name
Get-Command New-SmbShare | Format-List
Get-Command *Smb*

```
Enabling scripts
```powershell
Get-ExecutionPolicy
Set-ExecutionPolicy RemoteSigned # allows local scripts
```
## Strings, Patterns, Wildcards
```powershell
Get-ChildItem -Path "C:\Windows\*" -Filter *.exe
Get-ChildItem -Path "C:\Windows\*" | Where-Object { $_.Name -Match "^se" } # find files whose names start with "se"
```
the latter is the equivalent of the bash
```bash
ls /c/Windows/* | grep ^se
```
### String Manipulation
```powershell
"hello world".Split(" ")               # hello, world
"hello/world/mr.flibble".Split("[/.]") # hello, world, mr, flibble -- argument to Split is a regex
"a/b/c/d".Split("/").Count             # 4
```
