How to get name off current directory - batch-file

Question

I have been wanting my script to find a folder that starts with the string "onedrive...".
My code looks like this,
#echo off
set path="C:\Users\%USERNAME%"
if exist %path% (
cd "%path%\onedrive*"
echo %cd%
cd
)
pause
and the output I get is,
C:\Users\310176421\Backupscript\source
C:\Users\310176421\OneDrive for Business
where the first one is my .bat file directory and the second one is the line i want to make into a variable.
Any ideas?

Answer 1

Oh man don't do this, you are overwriting the system PATH. You have to use another name for that variable. And also you have to set it as local.
#echo off
SETLOCAL
REM blah blah
set _my_custom_path=....
ENDLOCAL

Answer 2

Here is a simple batch code which searches in profile directory of current user for a directory starting with string OneDrive and assigns the full path of first found folder without quotes to an environment variable output next before exiting batch.
#echo off
for /F "delims=" %%I in ('dir /AD /B /S "%USERPROFILE%\OneDrive*" 2^>nul') do (
set "OneDriveFolder=%%~I"
goto FoundFolder
)
echo Could not find a folder OneDrive.
goto :EOF
:FoundFolder
echo Found folder: %OneDriveFolder%
set "OneDriveFolder="
For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.
dir /?
for /?
goto /?
set /?
Note 1: C:\Users\%USERNAME% is not always equal %USERPROFILE% as the profile directory can be also on another drive than drive C: and Users is just the default parent directory for the user profiles on Windows Vista and later.
Note 2: 2^>nul redirects error message output by command DIR to stdout to device nul which means suppressing the error message in case of no directory starting with OneDrive is found case-insensitive. ^ escapes redirection operator > for command FOR to get 2>nul applied on command DIR.
