[英]Executed piped commands via System.Diagnostics.Process on Mono
Is it possible to execute the following piped commands via System.Diagnostics.Process
? 是否可以通过System.Diagnostics.Process
执行以下管道命令?
echo "test" | sudo -S shutdown -r +1
I've tried setting the file name to "/bin/bash", with the above as arguments, with no success. 我已经尝试将文件名设置为“/ bin / bash”,以上为参数,但没有成功。
...
var processStartInfo = new ProcessStartInfo { FileName = "/bin/bash", Arguments = "echo \"test\" | sudo -S shutdown -r +1" };
process.StartInfo = processStartInfo;
...
bash
is interpreting your command as a file name followed by arguments, meaning it invokes echo
and passes all the rest (including the pipe |
) to it for printing so you will get test | sudo -S shutdown -r +1
bash
的解释你的命令为文件名后面的参数,这意味着它调用echo
并将所有其他(包括管道|
)将其打印所以你会得到test | sudo -S shutdown -r +1
test | sudo -S shutdown -r +1
echoed and sudo
won't be executed. test | sudo -S shutdown -r +1
echoed和sudo
将不会被执行。
You should use the -c
option to execute a command. 您应该使用-c
选项来执行命令。 Furthermore, you should quote the command itself so that it gets passed as a single argument. 此外,您应该引用命令本身,以便它作为单个参数传递。 Something like this should work: 这样的事情应该有效:
var processStartInfo = new ProcessStartInfo
{
FileName = "/bin/bash",
Arguments = "-c \"echo test | sudo -S shutdown -r +1\""
};
