You can execute commands in parallel with `start` like this:

    start &quot;&quot; ping myserver
    start &quot;&quot; nslookup myserver
    start &quot;&quot; morecommands

They will each start in their own command prompt and allow you to run multiple commands at the same time from one batch file.

Hope this helps!

I suggest you to see &quot;[How do I run a bat file in the background from another bat file?][1]&quot;

Also, good answer (of using `start` command) was given in &quot;[Parallel execution of shell processes][2]&quot; question page [here][3];

But my recommendation is to use *PowerShell*. I believe it will perfectly suit your needs.

if you have multiple parameters use the syntax as below. I have a bat file with script as below:

    start &quot;dummyTitle&quot; [/options] D:\path\ProgramName.exe Param1 Param2 Param3 
    start &quot;dummyTitle&quot; [/options] D:\path\ProgramName.exe Param4 Param5 Param6 

This will open multiple consoles.


You can execute commands in parallel with `start` command, like:
```
start &quot;&quot; ping google.com
```
But to execute WITHOUT new window, use the [`/b`](https://www.computerhope.com/starthlp.htm) option, like:
```
start /b ping google.com -t
start /b ping example.com -t
```
&gt;Moreover, the `-t` option makes ping repeate infinite times.

I have a question about if - else structure in a batch file. Each command runs individually, but I couldn&#39;t use &quot;if - else&quot; blocks safely so these parts of my programme doesn&#39;t work. How can I do make these parts run? Thank you.

How to use if - else structure in a batch file?

I have a batch file that runs several python scripts that do table modifications.  

1. I want to have users comment out the 1-2 python scripts that they don&#39;t want to run, rather than removing them from the batch file (so the next user knows these scripts exist as options!)

2. I also want to add comments to bring to their attention specifically the variables they need to update in the Batch file before they run it. I see that I can use `REM`. But it looks like that&#39;s more for updating the user with progress after they&#39;ve run it.  

Is there a syntax for more appropriately adding a comment?


How to &quot;comment-out&quot; (add comment) in a batch/cmd?

I have a small utility script called `clear.bat` that does some housekeeping work on my sources.

It is a `.bat` file so that I could easily double-click it in Windows Explorer.

Sometimes, I find it more handy to execute it from my Git bash (msysgit, if this matters).

To do this, I type

    cmd
    clear.bat
    exit

`cmd` turns my Git bash into a normal `cmd` window where I could easily execute my batch. When I type `exit`, the `cmd` environment is terminated and I&#39;m back in my Git bash.

Could this be achieved in an easier way?

I tried `cmd /C clean.bat` since [the docs][1] say 

    Syntax
          CMD [charset] [options]

          CMD [charset] [options] [/c Command] 

          CMD [charset] [options] [/k Command] 

    Options   
       /C     Run Command and then terminate

       /K     Run Command and then return to the CMD prompt.
              This is useful for testing, to examine variables

- - -
**Edit:**  
Just noticed that the post is broken. 

What I want is to execute `clean.bat` from within the Git bash without having to type the three commands above (`cmd`, `clear.bat`, `exit`). I just want to execute the `.bat` file from within my Git bash. Obvious way would be to create a separate `.sh` file that does the same work but this will lead to double code.

- - -
**Edit 2:**
When I execute `cmd /C clean.bat`, the Git bash turns into a plain CMD environment and only displays the prompt. The file `clean.bat` does not get executed. It&#39;s the same as if I just type `cmd`.

Also, adding a `/debug` switch does literally nothing. Seems like only `cmd` gets evaluated and all further parameters are getting ignored.

Out of a git console: how do I execute a batch file and then return to git console?

I&#39;ve been writing some batch files, and I ran into [this user guide](http://www.tacktech.com/display.cfm?ttid=307), which has been quite informative. One thing it showed me was that lines can be commented not just with `REM`, but also with `::`. It says:

&gt; Comments in batch code can be made by using a double-colon, this is better than using the REM command because labels are processed before redirection symbols. `::&lt;remark&gt;` causes no problems but `rem &lt;remark&gt;` produces errors. 

Why then, do most guides and examples I see use the `REM` command? Does `::` work on all versions of Windows?

Which comment style should I use in batch files?

I need to delete all .jpg and .txt files (for example) in dir1 and dir2. 

What I tried was:

    @echo off
    FOR %%p IN (C:\testFolder D:\testFolder) DO FOR %%t IN (*.jpg *.txt) DO del /s %%p\%%t

In some directories it worked; in others it didn&#39;t. 

For example, this didn&#39;t do anything:

    @echo off
    FOR %%p IN (C:\Users\vexe\Pictures\sample) DO FOR %%t IN (*.jpg) DO del /s %%p\%%t

What I&#39;m I missing in the second snippet? Why didn&#39;t it work? 

Delete all files of specific type (extension) recursively down a directory using a batch file

I&#39;m trying to compile some java (learning java currently), and to do so I need to change command-prompt&#39;s directory.

    C:\...\Admin&gt; cd D:\Docs\Java
    C:\...\Admin&gt; cd
    C:\...\Admin

It doesn&#39;t change the directory. I try again using quotes:

    C:\...\Admin&gt; cd &quot;D:\Docs\Java&quot;
    C:\...\Admin&gt;

Again it doesn&#39;t change the directory. What am I doing wrong?
