Alias error with Exec on Linux

While doing Powershell development on Linux I encountered an issue running a psakefile.ps1. The component:

...
Task GitPull {
  Exec { git pull }
}
...

Expected Behavior

❯ invoke-psake GitPull
psake version 4.9.0

psake succeeded executing psakefile.ps1

At /home/paulhey/Projects/labcollector/psakefile.ps1:377 char:3 +   Exec { git pull } +   ~~~~~~~~~~~~~~~~~ [<<==>>] Exception: Command '' was not found. The specified command must be an executable.

Possible Solution

Current work around is to remove the alias so I can continue to run the script.

❯ Remove-Alias exec

Or add this line to your Profile script

Steps to Reproduce (for bugs)

Install Powershell 7.3.0
Install psake powershell module (4.9.0)
Create a psakefile.ps1 with an Exec statement in it
Run the Invoke-PSake against the task with the Exec statement

Context

I was attempting to use my psakefile to handle some automation steps. After the error was thrown I had though there was an issue with my psakefile (typo, etc) and so I opened it up into VSCode where I discovered that it was reporting Exec as an alias for Switch-Process (I found this online documentation). I may also have to open an issue with PSScriptAnalyzer or VSCode-PowerShell as the analyzer reports it as an alias instead of a function and the formatting tool wants to replace it as such. So with some additional troubleshooting, I am unable to reproduce this in PowerShell 7.2.* and with a bit of digging I found a PR on the main PowerShell repo for PowerShell 7.3.1, which looks to create a colliding function instead of an alias.

I have been unable to reproduce in Windows, as the alias Exec and function Switch-Process don't exist there.
