There are times when you want to batch rename files with a specific rule in a large number of files such as logs.
Renaming one by one is troublesome, so use Powershell to finish it in an instant.
Composing the commands is not difficult, so it's useful to remember.
Program
Get-ChildItem -File "Search condition to replace" | Rename-Item -NewName { $_.Name -replace 'Search condition to replace','Afterreplacement' }
sample
"-"
Get-ChildItem -File -path "*-*" | Rename-Item -NewName { $_.Name -replace '-','' }
Description
1) Get-ChildItem:
Only the file is extracted by attaching File Get-File. If you want to remove the folder, remove -File.
By the way, the ls command is an alias for Get-ChildItem, so ls will give the same result.
-path Sets the search condition to extract.
2)Rename-Item -NewName : Replace the specified characters
Rename-Item
Normally Rename-Item File before change File after change , since it is a pipeline, it works without specifying the pre-change file.
