运行批处理文件时找回的7-Zip的错误 [英] Retrieve an error of 7-zip when running a batch file

问题描述

我有一个批处理文件中，我执行以下命令行来列出归档的内容：

I have a batch file in which I execute the following line to list the contents of an archive:

"\Program Files\7-Zip\7z.exe" l "\Backup Google Docs.7z"

归档故意损坏。

cmd.exe的显示这样的：

cmd.exe displays this:

在同一批处理文件，执行以下，如何测试，有单词错误或不？

At the same batch file, following the execution, how to test that there is the word "error" or not?

推荐答案

所有程序的退出code存储在％ERRORLEVEL％在批处理脚本变量。

Any program's exit code is stored in the %ERRORLEVEL% variable in a batch script.

从7-ZIP手册：

7-Zip returns the following exit codes:

Code Meaning 
0 No error 
1 Warning (Non fatal error(s)). For example, one or more files were locked by some other application, so they were not compressed. 
2 Fatal error 
7 Command line error 
8 Not enough memory for operation 
255 User stopped the process 

所以：你可以这样做：

So: you can do:

"\Program Files\7-Zip\7z.exe" l "\Backup Google Docs.7z"
if errorlevel 255 goto:user_stopped_the_process
if errorlevel 8 goto:not_enough_memory
if errorlevel 7 goto:command_line_error
if errorlevel 2 goto:fatal_error
if errorlevel 1 goto:ok_warnings

注意，如果％ERRORLEVEL％大于或小于N等于错误级别ñ检查，因此，你应该把他们按降序排列。

Caution, if errorlevel N checks that %ERRORLEVEL% is greater or equal than N, therefore you should put them in descending order.
