在Unix shell脚本中,可以从内部脚本本身重定向stderr和stdout,如下所示:
#!/bin/ksh
# script_name: test.sh
export AUTO_LOGFILE=`basename $0 .sh`.log
# stdout and stderr Redirection. This will save the old stdout on FD 3, and the old stderr on FD 4.
exec 3>&0 4>&1 >>$AUTO_LOGFILE 2>&1
echo "Hello World"
# The above echo will be printed to test.log实际上,test.sh可以简单地执行为:
test.sh而不是:
test.sh >> test.log 2>&1 我正在试着在批处理脚本中做类似的事情。我的批次代码如下:
@echo off & setlocal enableextensions enabledelayedexpansion
REM script_name=test.bat
set AUTO_LOGFILE=%~n0.log
REM How to do the stdout and stderr redirection from within the script itself here?如何从批处理脚本本身重定向stderr和stdout?我更感兴趣的是将这个unix shell脚本语句转换成等价的批处理代码:
exec 3>&0 4>&1 >>$AUTO_LOGFILE 2>&1发布于 2012-04-22 01:03:41
下面的test.bat批处理文件在功能上等同于您的Unix脚本,即它将所有标准输出发送到日志文件,并将错误输出发送到屏幕:
@echo off
if defined reEntry goto reEntry
set reEntry=TRUE
set AUTO_LOGFILE=%~N0.log
rem stdout Redirection. Leave stderr as is.
"%~F0" %* >>%AUTO_LOGFILE%
:reEntry
set reEntry=
echo "Hello World"
rem The above echo will be printed to test.log
rem and error messages will be printed to the screen:

我以为OP希望将stdout与stderr分开,以便在屏幕上看到错误消息,但也许我误解了他。要将stdout和stderr发送到该文件,请使用dbenham注释中提到的以下行:
"%~F0" %* >>%AUTO_LOGFILE% 2>&1或者用上面的评论中已经建议的更简单的方式:
@echo off
set AUTO_LOGFILE=%~N0.log
rem stdout and stderr Redirection.
call :Main %* >>%AUTO_LOGFILE% 2>&1
goto :EOF
:Main
echo "Hello World"
rem The above echo will be printed to test.log但是,如果目的是区分错误消息和正常输出,则可以通过以下技巧在同一屏幕中完成此操作:
"%~F0" %* 2>&1 1>&3 | findstr /N /A:4E "^"这样,错误消息的前面会出现一个红色背景上的黄色行号。这种方法可以直接用于几种情况;例如,在任何编程语言源程序的编译中:
anycompiler %1 2>&1 1>&3 | findstr /N /A:4E "^"发布于 2012-04-20 16:02:39
将这些行括在括号中
