查找并删除在Ubuntu DOS行结束 [英] Find and remove DOS line endings on Ubuntu
问题描述
我发现我的很多文件具有DOS行结束。在六,他们看起来是这样的:^ M。
我不想修改没有这些DOS行结尾的文件。我如何做到这一点使用bash脚本?谢谢!
EV
的grep -url ^ M。 | xargs的fromdos
的grep让你有DOS行结束当前目录下的所有文件的清单。
-U
使得grep的考虑行结尾,而不是默认剥夺他们带走
-R
使得递归
-l </ code>使它只列出文件名,而不是匹配的行
那么你的管道,列出入转炉命令(即 fromdos
在Ubuntu上, DOS2UNIX的
我在哪里来自)。
注意:不实际键入 ^ M
。相反,你需要preSS &LT;按Ctrl-V&GT;
然后&LT;按Ctrl-M&GT;
插入 ^ M
字符,让grep的了解你要什么。或者,你可以代替键入 $'\\ r'
^ M
(但我认为这可能只是工作对于bash ...)。
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!
EV
grep -URl ^M . | xargs fromdos
grep gets you a list of all files under the current directory that have DOS line endings.
-U
makes grep consider line endings instead of stripping them away by default
-R
makes it recursive
-l
makes it list only the filenames and not the matching lines
then you're piping that list into the converter command (which is fromdos
on ubuntu, dos2unix
where i come from).
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 $'\r'
in place of ^M
(but i think that may only work for bash...).
