Piping in PowerShell

Piping in PowerShell

In PowerShell, the | character, also known as the pipe operator, is used to pass the output of one command as the input to another command.

This allows you to chain multiple commands together to create more complex and powerful scripts.

Examples

Example 1

Here's an example of using the pipe operator to pass the output of one command as the input to another command:

Get-Process | Where-Object CPU -gt 50

In this example, the Get-Process cmdlet is used to get a list of running processes on the system.

The | character is used to pass the output of this command as the input to the Where-Object cmdlet. The Where-Object cmdlet is used to filter the output of the Get-Process cmdlet, and it only includes processes with a CPU usage greater than 50%.

The code will output a list of processes with a CPU usage greater than 50%.

Example 2

You can also use the pipe operator to pass the output of multiple commands as the input to another command.

Here's an example:

Get-Process | Sort-Object CPU | Format-Table ProcessName, CPU

In this example, the Get-Process cmdlet is used to get a list of running processes on the system.

The Sort-Object cmdlet is used to sort the output of the Get-Process cmdlet by CPU usage. The Format-Table cmdlet is used to format the output as a table, with the columns ProcessName and CPU.

The code will output a table with the process name and CPU usage for each running process, sorted by CPU usage.

Conclusion

In PowerShell, the | character, also known as the pipe operator, is used to pass the output of one command as the input to another command.

The pipe operator is a tool in PowerShell that allows you to chain multiple commands together and pass the output of one command as the input to another. This allows you to create more complex and powerful scripts.
