SED without backup file
提问by LA_
I use the following sedcommand to replace text in the file:
我使用以下sed命令替换文件中的文本：
sed -i -e 's/noreply@\(.*\).example.com/[email protected]/' cron.yaml
But it create backup of the file cron.yamlunder name cron.yaml-e.
但它会cron.yaml在 name 下创建文件的备份cron.yaml-e。
I tried to move -ito the end:
我试图-i走到最后：
sed -e 's/noreply@\(.*\).example.com/[email protected]/' -i cron.yaml
but in this case sedreturns an error.
但在这种情况下会sed返回错误。

根据手册页，您应该在 macOS 上指定零长度扩展

On Windows the GNUWIN32 sed FAILS, when putting any of this:
在 Windows 上，GNUWIN32 sed 失败，当输入以下任何内容时：
sed -i "s/WhatToFind/WhatToPut/g" ".\MyDir\*"
sed -i "s/WhatToFind/WhatToPut/g" ".\MyDir\*"
sed -i.BackUp "s/WhatToFind/WhatToPut/g" ".\MyDir\*"
sed -i.BackUp "s/WhatToFind/WhatToPut/g" ".\MyDir\*"
The BackUps are allways created on actual folder with a file name pattern of sed$$$$$$, where that six $ represents random leters and numbers.
备份总是在实际文件夹中创建的，文件名模式为sed$$$$$$，其中六个 $ 代表随机字母和数字。
I see no way for it to not create any BackUP at all, neither to create BackUPs that can be know to which file was the source, neither create backups on the same folder as source file.
我看不出它根本不创建任何备份，既不能创建可以知道哪个文件是源的备份，也不能在与源文件相同的文件夹上创建备份。
And it also tries to read sub-foldersas is they where files, of courrse showing an impossible to readmessage for such sub-folders; and of course it does not recurse sub-folders, it only works with all on the same folder, but not with what is on sub-folders (not recursive).
并且它还尝试按sub-folders原样阅读files，当然会显示impossible to read此类信息sub-folders；当然它不会递归子文件夹，它只适用于同一文件夹中的所有内容，但不适用于子文件夹中的内容（非递归）。
In shorts words: -iis not working at all as spected.
简而言之：-i根本没有像预期的那样工作。

在 Google 上，我找到了一个讨论该 BUG 的网站，并建议下载一个ssed替代sed工具，我有点害怕没有official；链接到我在 Google-i上发现的关于该BUG 的内容sed：http: //www.thinkplexx.com/learn/snippet/cmd/one-liner/working-in-place-sed-option-under-windows
