No operation command

Question

With Bash, you have the command :

Null command.

No effect; the command does nothing.

Exit Status:
Always succeeds.

Example

: 'foo'

Does PowerShell have something similar to this?

Answer 1

With the above example, the ForEach-Object alias % works

% 'foo'

Or

function : {}
: 'foo'

Or

[void] 'foo'

Answer 2

Another even shorter solution is to use the alias of Where-Object which is ?.

This command line does nothing (and succeeds):

? .

The trick is simply to pass a single-character argument so that the command does not fail and which has no special meaning in powershell.
