資料夾有一堆檔案感覺很亂.....

若想要依據檔案的最後修改日期分類,例如依據年月
我們可使用以下的Script

#使用get-content path顯示檔案內容
PS C:\> get-content c:\a.txt

#使用${path} 顯示檔案內容
PS C:\> ${C:\a.txt}

#產生內容為PowerShell的char陣列
PS C:\> [char[]]$Array = "P","o","w","e","r","S","h","e","l","l"

#預設將陣列轉為字串時是以空白隔開

• 輸入:  "2+2 is (2+2)"
  結果:   2+2 is (2+2)
• 一般字串
• 輸入:  "2+2 is $(2+2)"
  結果:   2+2 is 4
• 雙引號中會將$開頭的作解析,括號內解析為4
• 輸入:  "2+2 is $2+2"
  結果:   2+2 is +2
• 雙引號中會將$開頭的作解析,$2無此變數因此不顯示,+2視為一般字串;若是事先定義$2="a",則結果為2+2 is a+2
• 輸入:  '2+2 is (2+2)'
  結果:   2+2 is (2+2)
• 單引號所見及所得
• 輸入:  '2+2 is $(2+2)'
