Whereas Windows Script Host programs use objects as tools to perform Windows management and data-processing tasks, batch files use entire programs as their tools.

WSH scripts give you great control of the details of a task, whereas batch files let you work at a grosser, macro level. So, just as it's an advantage to have both small and large wrenches in your toolbox, it's an advantage to know how to write both scripts and batch files.

Furthermore, like Windows Script programs, batch files serve as a form of documentation, because they capture critical business management information—procedures and configuration data—in written form.

In unix-style shells, this is done via backquoting. The Windows command processor does not have direct backquoting, but you can fake it by abusing the FOR command.

The loop variable in the FOR command takes one percent sign if you are executing it directly from the command prompt, but two percent signs if you are executing it from a batch file. By default, the FOR command sets the loop variable to the first word of each line. If you want to capture the entire line, you need to change the delimiter. There are other options for capturing say the first and third word or whatever.

Since the program has only one line of output, the loop executes only once, and the result is that the directory is changed to the path that the printappdir program prints. Exercise: What if you want to extract more than 26 words? Note also that the above script works only for US-English systems, since the phrase IPv4 Address will change based on your current language. This alternate version makes the findstr program do the heavy lifting, and then saves the fourteenth word.

But this version will get fooled by the line Autoconfiguration IPv4 Address. This site uses cookies for analytics, personalized content and ads. By continuing to browse this site, you agree to this use.
