Common PowerShell Commands

Recently, WebShell needed to support file management under PowerShell. To perform file-related operations, it’s necessary to understand the relevant commands. Here’s the summary.

Compress Folder

Compress-Archive -Path '${formatted}' -DestinationPath '${zipTempPath}'

Copy File/Folder

Copy-Item -Path '${filePath}' -Destination '${dirPath}' -Recurse -Force

Move File/Folder

Move-Item -Path '${filePath}' -Destination '${targetPath}' -Force

Extract ZIP Archive

Expand-Archive -Path '${path}.zip' -DestinationPath '${destinationPath}';Remove-Item -Path '${path}.zip' -Force

Delete File/Folder

Remove-Item -Path '${formatted}' -Recurse -Force

Create Folder

New-Item -Path '${formatted}' -ItemType Directory

Rename

Rename-Item -Path '${formatted}' -NewName '${newName}'

Multiple Command Execution

If need to execute multiple commands, unlike using && in Linux, PowerShell requires ;.

Move-Item -Path '${path}' -Destination '${path}.zip';Expand-Archive -Path '${path}.zip' -DestinationPath '${destinationPath}';Remove-Item -Path '${path}.zip' -Force

Common Issues

w2: Cannot load file C:\Program Files\node js\w2.ps1 because running scripts is disabled on this system.

# Run PowerShell as administrator

# Check the current PowerShell script execution policy
get-ExecutionPolicy
# Set PowerShell's execution policy to RemoteSigned
set-executionpolicy remotesigned

Path Contains Square Brackets []

If the path contains [], for example, executing Move-Item doesn’t throw an error but the execution is unsuccessful. The reason is that [] in the path is treated as regex, regardless of whether it’s a single or double quote. There are two solutions:

1. Escape []

   For example:

   Move-Item -Path 'C:\\Windows\\Temp\\`[漫威`] xxx.jar_1717312576427' -Destination 'C:\\Windows\\system32\\config\\systemprofile\\`[漫威`] xxx.jar' -Force
   

2. Change -Path to -LiteralPath

   Move-Item -LiteralPath 'C:\\Windows\\system32\\config\\systemprofile\\123 456\\[漫威] xxx.jar' -Destination 'C:\\Windows\\system32\\config\\systemprofile\\789\\[漫威] xxx.jar' -Force
   

Final Thoughts

When executing Windows commands, you can choose between PowerShell and CMD. According to Microsoft’s recommendation, using PowerShell is advised, as CMD has entered the maintenance phase.
