dos2unix, unix2dos 用來實現 DOS <=> UNIX text file 轉換
aptitude install sysutils
行末：
DOS 格式 0d 0a
UNIX 格式 0a

可用功能相同的指令組合
dos2unix:
sed -i'' "s/\r//" file
或
cat file | col -b > newfile
或
cat file | tr -d "\r" > newfile
或
cat file | tr -d "\015" > newfile

unix2dos:
sed -i'' "s/$/\r/" file
或
sed -i'' "s/$/\x0d/" file

-i后面的是單引號組成

以上適用 GNU sed, FreeBSD 下的 sed 不適用

dos2unix 命令

這是一個很簡單的命令.功能是將DOS/MAC下的文件轉化為UNIX的文本文件格式.用法詳見下面.
就是這樣一個簡單的命令折騰了我大半天.我在用mysql查詢數據庫,執行的批處理放在了一個文件里.如果我執行這個文件,那個存放查詢結果的 文件名字總是在后面附加一個?號.而如果我一行一行敲入命令,執行就正常.而且比較了兩個文件后沒有差別.還有一個奇怪的事情就是總是出現一個類似 "quit"出現mysql語法錯誤的提示.這個奇怪的現象使我很困惑.后來在一位老大的幫助下想到了是不是由于文件格式的差別.因為我這個文件在 windows下編輯過,后來一試,果然很靈啊.
