相同的文件內容但不同的md5sum值？

Question

我發現了一個奇怪的問題。 pam 無法正確讀取common-account.puppet pam可以正確讀取common-account.written。

但他們的文字是一樣的，採用MELD和Vimdiff可以

md5sum common-account.puppet common-account.written 
7e80513f6dc8f7604ec36dbf6248780d common-account.puppet 
47425f79f81d38eadbadb0c3de89aafc common-account.written 

我不知道什麼是兩者之間的區別。任何顯示更多差異日誌的命令？

kithokit@15:46:58 ~ $ md5sum common-account.puppet common-account.written 
7e80513f6dc8f7604ec36dbf6248780d common-account.puppet 
47425f79f81d38eadbadb0c3de89aafc common-account.written 
kithokit@15:47:08 ~ $ diff common-account.puppet common-account.written

謝謝如果你能幫助

這些文件看起來是一樣的，但7e80513f6dc8f7604ec36dbf6248780d與Windows EOL字符的文件，而47425f79f81d38eadbadb0c3de89aafc和Unix的EOL相同的文件。

我們可以使用

vim -b <filename> 

顯示，如果有^該文件字符M。

如果是的話，手動刪除它或者exec

dos2unix <filename>
