In PowerShell, the equivalent of bash's exec() function is the Start-Process cmdlet. This cmdlet allows you to start a new process, just like exec() in bash, by specifying the path to the executable file and any arguments that need to be passed. Additionally, the Start-Process cmdlet also provides various options and parameters that can be used to control how the new process is started and managed.

How to run commands asynchronously in Powershell?
To run commands asynchronously in Powershell, you can use the Start-Job cmdlet. Here's how you can do it:
- Use the Start-Job cmdlet to start a background job for the command you want to run asynchronously. For example:
1
|
Start-Job -ScriptBlock { Get-Process }
|
In this example, the Get-Process command will be run in a background job.
- You can also specify a name for the job using the -Name parameter:
1
|
Start-Job -Name "GetProcesses" -ScriptBlock { Get-Process }
|
- You can check the status of the job using the Get-Job cmdlet:
1
|
Get-Job
|
This will show you a list of all the background jobs that are currently running.
- You can retrieve the output of the job using the Receive-Job cmdlet:
1
|
Receive-Job -Name "GetProcesses"
|
This will show you the output of the job with the specified name.
- You can also remove a job using the Remove-Job cmdlet:
1
|
Remove-Job -Name "GetProcesses"
|
This will stop and remove the job with the specified name.
By using the Start-Job cmdlet and other related cmdlets, you can run commands asynchronously in Powershell and manage background jobs effectively.
