If you just want to delete the duplicate data and sort out the list without duplicate. you can easily use the excel function is okay.
Highlight the column that you need to sort
Under the data -> Remove Duplicates
Then a table pop out
press OK
Then it will show how many duplicate data is delete and how many data is unique and remain.
press OK
windows下安裝 UnxUtils -- 仿 unix/linux 命令
sort.exe -u -m < input.txt > output.txt
註: -u 表示 "唯一" 或 "相同者取其一"
如何利用 仿unix命令 sed 一次替換文字中的 "某些相似性的字串"
