Bash将所有stdout输出到控制台和文件(Bash output all stdout both to console and file)

 我试图将所有stdout和stderr到控制台和文件。 我知道./script | tee somefile ./script | tee somefile ，但这对我不起作用。 我想让它自动完成，而不是我从控制台管道。 我试过了 
 
#!/bin/sh
exec 2>&1 | tee somefile
echo "..."
 
 但那没用。 什么是正确的解决方案？ 

I am trying to output all stdout and stderr both to console and to a file. I know about ./script | tee somefile , but that doesn't work for me. I want it to do it automatically, without me piping it from the console. I've tried 
 
#!/bin/sh
exec 2>&1 | tee somefile
echo "..."
 
but that didn't work. What would be the correct solution?
