I have found that many of my files have DOS line endings. In VI they look like this: "^M". I don't want to modify files that don't have these DOS line endings. How do I do this using a bash script? Thanks!

推荐答案

grep -URl ^M . | xargs fromdos

grep 为您提供当前目录下具有 DOS 行结尾的所有文件的列表.

grep gets you a list of all files under the current directory that have DOS line endings.

-U 使 grep 考虑行尾而不是默认将它们剥离

-U makes grep consider line endings instead of stripping them away by default

-R 使其递归

-l 使它只列出文件名而不列出匹配的行

-l makes it list only the filenames and not the matching lines

然后您将该列表传送到转换器命令中(在 ubuntu 上为 fromdos，dos2unix 我来自哪里).

then you're piping that list into the converter command (which is fromdos on ubuntu, dos2unix where i come from).

注意:实际上不要输入 ^M.相反，您需要按 然后按 插入 ^M 字符并使grep 明白你要做什么.或者，您可以输入 $' ' 代替 ^M (但我认为这可能只适用于 bash ......).

NOTE: don't actually type ^M. instead, you'll need to press <Ctrl-V> then <Ctrl-M> to insert the ^M character and make grep understand what you're going for. or, you could type in $' ' in place of ^M (but i think that may only work for bash...).
