Display running processes with the Get-Process cmdlet

\n

In PowerShell, you can use the Get-Process command to retrieve a list of running processes.

\n

With Get-Process, you can obtain parameters such as the process name and process ID, as shown below.

\n

The aliases for Get-Process are gps and ps.
\nIt is convenient that it can be used in a Linux-like way.

\n
PS C:\\Users\\yuki> Get-Process\n\nHandles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName\n-------  ------    -----      -----     ------     --  -- -----------\n    393      23    16348      30068       0.19   7836   2 ApplicationFrameHost\n    569      28    65592      75100   5,603.98  10060   0 audiodg\n    308      35    33364      82540       1.48   1308   2 Code
\n

In addition, with Get-Process you can specify which process to display by using the process ID or process name, as shown below.
\nThis is normally used to obtain a known running process, so an error occurs if no matching process is found.

\n
# Specify a process by process name\nPS C:\\Users\\yuki> Get-Process -Name code\n\nHandles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName\n-------  ------    -----      -----     ------     --  -- -----------\n    821      44    38760      87176      12.59   1364   3 Code\n    245      21    15188      27940       0.19   4216   3 Code\n    531      82   158264     180296      37.78   4984   3 Code\n    657      29   180360     197764       8.73   7232   3 Code\n    400      51    43332      70696      13.98  10328   3 Code\n    438      20     9688      25920       1.11  10820   3 Code\n    311      35    33060      51808       1.48  11996   3 Code\n    227      16     6896      14048       0.09  14204   3 Code\n\n# Specify a process by ID\nPS C:\\Users\\yuki> Get-Process -Id 4216\nHandles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName\n-------  ------    -----      -----     ------     --  -- -----------\n    245      21    15188      27948       0.19   4216   3 Code
\n

By the way, you can also use wildcards in the process-name search like this.
\nIn this example, specifying note* successfully extracts the notepad process.

\n
PS C:\\Users\\yuki> Get-Process -Name note*\n\nHandles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName\n-------  ------    -----      -----     ------     --  -- -----------\n    290      17     4068      18728       0.17   4504   3 notepad
\n

Stop a specific process with the Stop-Process command

\n

You can also use the Stop-Process command to stop a specific process by specifying the process name or process ID.
\nThe aliases for Stop-Process are kill and spps.

\n

The kill command is the same as in Bash, so it is very easy to use.

\n

In the following example, Stop-Process is used to stop the notepad process.

\n
# Confirm that the notepad process is running\nPS C:\\Users\\yuki> Get-Process -Name note*\n\nHandles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName\n-------  ------    -----      -----     ------     --  -- -----------\n    290      17     4068      18728       0.17   4504   3 notepad\n\n# Stop the notepad process\nPS C:\\Users\\yuki> Stop-Process -Name notepad\n\n# When you check for the notepad process again, an error is returned because the process is no longer found\nPS C:\\Users\\yuki> Get-Process -Name notepad\npython -q\necho  行:1 文字:1\n+ Get-Process -Name notepad\n+ ~~~~~~~~~~~~~~~~~~~~~~~~~\n    + CategoryInfo          : ObjectNotFound: (notepad:String) [Get-Process], ProcessCommandException\n    + FullyQualifiedErrorId : NoProcessFoundForGivenName,Microsoft.PowerShell.Commands.GetProcessCommand
\n

You can also perform more complex processing by using command output in this filter portion.

\n

For example, the official documentation introduces the following one-liner for stopping all processes in a “Not Responding” state.

\n
Get-Process | Where-Object -FilterScript {$_.Responding -eq $false} | Stop-Process
\n

It is pretty convenient to be able to quickly stop non-responsive processes.
\nYou no longer have to visually search for them one by one in Task Manager.

\n

Summary

\n

This time, I summarized the Get-Process command for checking PowerShell processes and the Stop-Process command for stopping any process.
\nMany PowerShell commands are assigned the same aliases as familiar Bash commands, and I find them very comfortable to use.
