The first step might be to reduce excessive whitespace: ps -aux | grep cron | tr -s ' ' Assuming this is the case, we need to access the second column in the first line.

The cron PID appears to be 1041 although it's hard to tell without seeing the table headers. A first attempt might be as follows: ps -aux | grep cron For example, say you would like to find the PID of the cron service. And because PowerShell objects generally have a plethora of properties associated with them, you can do some fairly powerful things relatively easily. For example, there's no need to parse text to extract information from another output stream. Which begs the question, why would you want to use PowerShell over the native version? One key reason is that objects, and not simple data streams, are piped between PowerShell cmdlets. The PowerShell analog of this is as follows: Get-ChildItem | Sort-Object -Descending | Out-Host -Paging That is, the data stream output of the ls command is piped to the sort command whose data stream output is then piped to the more command. This reverse sorts the contents of the current directory and paginates the list (if necessary). In Linux, the output of one command can be piped into another command. To view a list of the available Linux PowerShell cmdlets, run Get-Command. For example, the PowerShell Get-Acl cmdlet is not applicable for Linux systems in that the Linux file system does not use NTFS access control lists (ACLs). Because of fundamental differences in operating systems, some PowerShell commands (called cmdlets) do not make sense. PowerShell runs on Windows, Linux, and the macOS operating systems.

PowerShell is made up of a command-line shell, a scripting language, and a configuration management framework. PowerShell is a cross-platform solution commonly used for automating the management of computer systems but it can be used for general coding as well.
