# Bash to PowerShell

Sometimes you need to leave your favorite tool to use a lesser loved one...

## variable and env vars

read:
`$<variable-name>`
`$Env:<variable-name>`

set:
`$<variable-name>=<numerical value>`
`$<variable-name>="<text value>"`
`$Env:<variable-name>=<var value>`

## multi line command


| bash | powershell
|:-----|:----------|
| \ | \` |

exemple:
```
docker run `
 -env var1=val1 `
myimage:latest
```

## chaining commands

in PowerShell, use a semicolon to chain commands :
`ipconfig /release ; ipconfig /renew `  
Use the `&&` or `||`operators to execute conditionnaly second command.


## GREP => Select-String

Basic usage:
`grep <searchedString> <file>`
`Select-String <searchedString> <file>`  

*searchedString* can be a regexp 

to search lines that do not contains use `-NotMatch` option  
`grep -v <searchedString> <file>`
`Select-String -NotMatch <searchedString> <file>`  

## rm -rf

`rm -rf <pathto-remove>`
`Remove-Item -Force -Recurse -Path "<pathto-remove>"`
