how to direct output into a txt file in bat script in windows
提问by jojo
in linux, let say i want to start tomcat, and want to direct all the console log into a text file, i can do write a bash script:
在 linux 中，假设我想启动 tomcat，并且想将所有控制台日志定向到一个文本文件中，我可以编写一个 bash 脚本：
./startup.sh > output.txt
./startup.sh > 输出.txt
but in windows, can we do the similar stuff using .bat script.
但是在 Windows 中，我们可以使用 .bat 脚本来做类似的事情吗？
how can i write this bat script???
我该如何编写这个 bat 脚本？？？
(i know the proper way should ask the application to do the log, but the application is not written by me, they print the log using system.out.print, all the logs are in the console, but i want to archive the log, in case something happen i can back trace)
（我知道正确的方法应该让应用程序做日志，但应用程序不是我写的，他们使用 system.out.print 打印日志，所有日志都在控制台中，但我想归档日志，万一发生什么事我可以回溯）

It's exactly the same in Windows.
这在 Windows 中完全相同。
i.e
IE
ping google.com > logfile.txt
or in powershell you could do the following to display the log to console as well
或者在 powershell 中，您也可以执行以下操作以将日志显示到控制台
ping google.com | tee-object -filepath C:\mylog.txt

You can write a bar script to do all that you want and then send the entire output to a file or you can specify some portion of the output to file by specifying the redirection in side the .bat file.
您可以编写一个 bar 脚本来完成您想要的所有操作，然后将整个输出发送到一个文件，或者您可以通过在 .bat 文件旁边指定重定向来指定输出的某些部分到文件。
