# Command Detail - C

## cal

There's no one-liner equivalent for the Linux `cal`, but there's a useful script, with much of the `cal` functionality here :

## cd

The PowerShell equivalent of `cd` is:

```
Set-Location
```

...although there is a builtin PowerShell alias `cd` which points at `set-location`

### cd \~

`cd ~` moves you to your home folder in both unix and Powershell.

## clear

The unix `clear` command clears your screen. The Powershell equivalent to the unix `clear` is

```
clear-host
```

PowerShell also has built-in alias `clear` for `clear-host`.

However, it's possibly worth noting that the behaviour of the two commands is slightly different between the two environments.

In my Linux environment, running putty, `clear` gives you a blank screen by effectively scrolling everything up, which means you can scroll it all back down.

The Powershell `Clear-host` on the other hand seems to wipe the previous output (actually in the same way that cmd's `cls` command does....). This *could* be quite a significant difference, depending on what you want to clear and why!

## cp

The Posh version of cp is

```
copy-item
```

The following are built-in aliases for copy-item:

```
cp

copy
```

## cp -R

To recursively copy:

```
copy -recurse
```
