Trying to get a rought sense, how postgresql got compiled. I want it run ./configure and also pipe the output info into a text file.

 sudo ./configure | /home/jian/fo1.txt

Error:

./configure: line 2885: printf: write error: Broken pipe

This could be helpful: What are the shell's control and redirection operators? — terdon, Jul 14 '22 at 15:47

The operator you search for is >. This redirects the output of a command to a specific device or file:

sudo ./configure >output_file.txt

If you want to capture errors (STDERR) in different file you should use:

 sudo ./configure >output_file.txt 2>>output_err.txt

If you want to append the output to existing file you should use >>

sudo ./configure >>output_file.txt

You don't need sudo on your ./configure line.

Your command should probably be:

./configure. |& tee home/jian/fo1.txt

You will probably have to clean up all the root-owned files you created with your previous attempt, thusly:

sudo find . -maxdepth 1 -user root -ls
# when you're happy with the list of files, replace `-ls` with `-delete`.
sudo find . -maxdepth 1 -user root -delete
