While creating a batch file, you can also enable loops (for), conditional statements (if), control statements (goto), etc. You can run a batch file directly from the command prompt by typing its name. Also, you can run one batch file from another batch file using the CALL command. Wha...
This batch script snippet checks for the existence of a file named “myfile.txt” using the “if-not-exist” conditional statement. If the file doesn’t exist, it echoes “File not found” and uses “goto” to jump to the “:error” label which indicates that an error occurred. If th...

goto:goto用于在同一个batch file中进行跳转,该命令会让cmd直接跳转到指定的标签行继续往下执行,如果遇到exit就直接退出了。而call在调用同一batch file中的过程调用的时候,也会跳转标签处继续往下执行,遇到exit不会直接退出,而是回到call的下一行继续执行。 call:call可以调用同一batch file中的过程调用,也可以调用外部...

You can include any command in a batch file. Certain commands, such as for, goto, and if, enable you to do conditional processing of the commands in the batch file. For example, the if command carries out a command based on the results of a condition. Other commands allow you to ...

批处理文件具有.bat或者.cmd的扩展名,其最简单的例子,是逐行书写在命令行中会用到的各种命令。更复杂的情况,需要使用if,for,goto等命令控制程序的运行过程,如同C,Basic等中高级语言一样。如果需要实现更复杂的应用,利用外部程序是必要的,这包括系统本身提供的外部命令和第三方提供的工具或者软件。
For example, use: if "%1" == somestring somecommand The "goto" command Generally, the execution of a batch file proceeds line-by-line with the command(s) on each line being run in turn. However, it is often desirable to execute a particular section of a batch file while skipping ...
