Question

以下是我发现的解决方案： Create a pipe that writes to multiple files (tee)

因此，下面的代码将stdout和stderr重定向到日志文件，同时在终端中显示它们。我想知道是否还有将stdin重定向到终端和日志文件。

#!/bin/bash 
LOG=./file.log 
PIPE=./logPipe
mkfifo ${PIPE}
exec 3>&1 4>&2
tee -a ${LOG} <${PIPE} >&3 &
exec 1>${PIPE} &
exec 2>&1

printf "%s\n" " Enter Something "
read something

printf "%s\n" " Enter Something "
read something2
printf "\n"

printf "%s\n" " Enter Something "
read something3

mkdir ./test
mkdir ./test
mkdir ./test here

printf "$something $something2 $something3" >> something.out

您可以使用脚本命令

script -c infile.sh

-c, --command command
  Run the command rather than an interactive shell. This makes it easy for a
  script to capture the output of a program that behaves differently when its
  stdout is not a tty.
