Suppress error messages in Windows commandline

Question

Let's say I already have a folder created on the next path file: "C:\users\charqus\desktop\MyFolder", and I run the next command on CMD:

mkdir "C:\users\charqus\desktop\MyFolder" 

I get a message like this: "A subdirectory or file C:\users\charqus\desktop\MyFolder already exists".

Therefore, is there any command in the commandline to get rid of this returned messages? I tried echo off but this is not what I looking for.

Answer 1

Redirect the output to nul

mkdir "C:\users\charqus\desktop\MyFolder" > nul 

Depending on the command, you may also need to redirect errors too:

mkdir "C:\users\charqus\desktop\MyFolder" > nul 2> nul 

Microsoft describes the options here, which is useful reading.

Answer 2

A previous answer shows how to squelch all the output from the command. This removes the helpful error text that is displayed if the command fails. A better way is shown in the following example:

C:\test>dir      Volume in drive C has no label.      Volume Serial Number is 4E99-B781       Directory of C:\test      20/08/2015  20:18    <DIR>          .     20/08/2015  20:18    <DIR>          ..                    0 File(s)              0 bytes                    2 Dir(s)  214,655,188,992 bytes free  C:\test>dir new_dir >nul 2>nul || mkdir new_dir >nul 2>nul || mkdir new_dir  C:\test>dir new_dir >nul 2>nul || mkdir new_dir >nul 2>nul || mkdir new_dir 

As is demonstrated above this command successfully suppress the original warning. However, if the directory can not be created, as in the following example:

C:\test>icacls c:\test /deny "Authenticated Users":(GA) processed file: c:\test Successfully processed 1 files; Failed processing 0 files  C:\test>dir new_dir2 >nul 2>nul || mkdir new_dir2 >nul 2>nul || mkdir new_dir2 Access is denied. 

Then as can be seen, an error message is displayed describing the problem.
