sed脚本-临时文件的权限被拒绝

问题描述

我只是使用find和sed的组合来替换目录文件中的字符串.

find . -type f -exec sed -i 's,foo,bar,g' {} +

它完成了工作.之后，我注销了服务器(通过SSH连接)，然后记住，我需要再次运行该命令.所以我用稍微修改的查找/替换字符串触发了相同的命令，但是它不再起作用，并给出以下错误:

sed: couldn't open temporary file ./sedPFq4Ck: Permission denied

现在怎么了?

FWIW:每次尝试后，上述临时文件的文件名都会更改.

解决方案

在适当位置编辑文件时，sed创建一个临时文件，保存结果，然后最终将mv与该临时文件保存在一起.mv /p>

问题是您在sed试图创建临时文件的目录中没有写许可权.

由于文件为./sedPFq4Ck，请检查运行find命令的目录的权限.

I just used a combination of find and sed to replace strings in files of a directory.

find . -type f -exec sed -i 's,foo,bar,g' {} +

It got the job done. After that I logged off the server (connected via SSH), and then remembered, that I need to run the command again. So I fired the same command with slightly modified find/replace strings, but it did not work anymore giving the following error:

sed: couldn't open temporary file ./sedPFq4Ck: Permission denied

What is wrong now?

FWIW: the file name of the mentioned temporary file changes after each new try.

解决方案

While editing a file in place, sed creates a temporary file, saves the result and then finally mv the original file with the temporary one.

The problem is that you don't have write permission in the directory where sed is trying to create the temp file.

As the file is ./sedPFq4Ck, check the permission of the directory where you are running the find command.
