Powershellでフォルダ内のファイル名の取得
結果はコピペでexcelに貼り付けできます。
get-childitem は、lsでもdirでも同じく使えるよ。
select-objectのエイリアスは%。
拡張子あり
get-childitem | select-object name
拡張子なし
get-childitem | select-object basename
拡張子のみ
get-childitem | select-object extension
エイリアスで
ls | % name
ls | % basename
ls | % extension
ls | % name は
For-Eachを使って ls | %{ $_.name }にもなる。
CSVに出力も。
get-childitem | select-object basename | export-csv c:\tmp\aaa.csv
ls | % basename | export-csv c:\tmp\aaa.csv
ついでにファイル名の一括変更
使い方
Get-ChildItem ＜対象ファイル＞ | Rename-Item -NewName { $_.Name -replace '旧文字列','新文字列' }
エイリアスで、
ls *.jpg | ren -newname { $_.name -replace '旧文字列', '新文字列' }
拡張子を変更する
dir | rename-item -newname {$_.name -replace '\.jpg$','.jpeg'}
-whatif 付きでテスト
dir | rename-item -newname {$_.name -replace '\.jpg$','.jpg'} -whatif

変数はこれ
プロパティはselect-objectできるはず。
