试图弄清楚postgresql是如何编译的。我希望它运行./配置，并将输出信息输送到文本文件中。

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

错误：

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

Answer 1

您搜索的运算符是>。这会将命令的输出重定向到特定的设备或文件：

sudo ./configure >output_file.txt

如果要捕获不同文件中的错误(STDERR)，应使用：

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

如果要将输出附加到现有文件，则应使用>>

sudo ./configure >>output_file.txt

Answer 2

您不需要sudo在您的./configure线路上。

你的命令应该是：

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

您可能需要清理之前尝试创建的所有root-owned文件，如下所示：

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
