How to do a for loop in windows command line

Question

I was wondering if this was possible  I m not familiar with using windows command line  but I have to use it for a project I m working on  I have a a number of files  for which I need to perform a function for each  I m used to working with python  but obviously this is a bit different  so I was hoping for some help    Basically I need the for loop to iterate through 17 files in a folder  perform a function on each  that s using the specific software I have here for the project  and then that will output a file with a unique name  the function normally requires me to state the output file name  I would suck it up and just do it by hand for each of the 17  but basically it s creating a database of a file  and then comparing it to each of the 17  It needs to be iterated through several hundred times though  Using a for loop could save me days of work   Suggestions

You might also consider adding     For example for  i in    wav  do opusenc    ni wav     ni opus  is very good idea

The commandline interpreter does indeed have a FOR construct that you can use from the command prompt or from within a batch file   For your purpose  you probably want something like   FOR  i IN    ext  DO my-function  i   Which will result in the name of each file with extension   ext in the current directory being passed to my-function  which could  for example  be another  bat file    The    ext  part is the  filespec   and is pretty flexible with how you specify sets of files  For example  you could do   FOR  i IN  C  Some Other Dir   ext  DO my-function  i   To perform an operation in a different directory   There are scores of options for the filespec and FOR in general  See  HELP FOR   from the command prompt for more information

This may help you find what you re looking for    Batch script loop   My answer is as follows    echo off  start set  a var  1 if  var  EQU 100 goto end    Code you want to run goes here goto start   end echo var has reached  var   pause exit   The first set of commands under the start label loops until a variable   var  reaches 100  Once this happens it will notify you and allow you to exit  This code can be adapted to your needs by changing the 100 to 17 and putting your code or using a call command followed by the batch file s path  Shift Right Click on file and select  Copy as Path   where the comment is placed
