How would I create a text file and fill it with sudo permission in bash
提问by richard_d_sim
I'm trying to create and fill a file in a directory that requires sudo permission.
我正在尝试在需要 sudo 权限的目录中创建和填充文件。
EDIT: It seems that based on tested the suggested similar post.
编辑：似乎基于测试建议的类似帖子。
sudo su -c "echo 'put in file' > file_name"
echo "Some text" | sudo tee /etc/file
will both create a file within the directory that requires sudo permission
都将在需要 sudo 权限的目录中创建一个文件

The question has been edited to include a log of the problem being introduced, which includes the command:
该问题已被编辑为包括所引入问题的日志，其中包括以下命令：
# Taken from edited question
$ echo 'hello' > sudo tee /data/hello
In bash (which allows redirection operators at any point in a simple command), this is precisely equivalent to running:
在 bash 中（它允许在简单命令中的任何点使用重定向操作符），这完全等同于运行：
# From question, with redirection moved to end to make actual behavior more readable
echo 'hello' tee /data/hello > sudo
That is, it's creating a file named sudoin your current directory, not using sudoto run tee(in the above, teeis just an argument to echo).
也就是说，它正在创建一个在您当前目录中命名sudo的文件，而不是sudo用于运行tee（在上面，tee只是一个参数echo）。
What you want, by contrast, is:
相比之下，你想要的是：
# CORRECT: Using a pipe, not a redirection
echo 'hello' | sudo tee /data/hello
with a pipe (|) rather than a >.
使用管道 ( |) 而不是>.

Assuming you have the required sudo privileges you could use an editor like vior nano
假设您拥有所需的 sudo 权限，您可以使用vi或nano等编辑器
sudo vi /etc/file
or
或者
sudo nano /etc/file
If you don't have sudo for those programs you can su to root first and then try:
如果你没有这些程序的 sudo 你可以先 su 到 root 然后尝试：
sudo su -
vi /etc/file
or
或者
nano /etc/file

If you want to do it all on one command line, you can make sure that the file exists by running touch(1) on it. E.g.
如果您想在一个命令行上完成所有操作，您可以通过在文件上运行 touch(1) 来确保该文件存在。例如
sudo touch /etc/file && echo "Some text" | sudo tee /etc/file
sudo touch /etc/file && echo "Some text" | sudo tee /etc/file
