My computers have mixed case names and I use these mixed case names in directories on some NAS devices. I wanted to use these names in some .bat files and would prefer to have the same .bat files on each computer rather than custom files on each computer. But I just discovered that %computername% returns upper case. Is there some other variable that returns the true name?
This is on Win10 1909.
The easiest workarounds would be
1 In any If statement, use the /I switch so that the comparison is done without regard to case.
2 At the start of your batch files you could insert an If statement that retrieves the proper computername and uses it to set a ThisComputer variable that has the format you prefer to work with within the batch file.

Try3 is right. Don't depend on case to make decisions.
But if you must get the "right" spelling, get it from the registry.
One place is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.
The "HostName" value found there will contain the proper host name.
An "If" statement is not involved. I'm using the computer name as part of a (case sensitive) path name on a NAS device:
Uh, OK. How do I access registry records in a .bat file. Or do I need to switch to a PowerShell script? (I know little about .bat scripting and nothing about PowerShell.)Synchronize Remote -Delete "F:\Test" "/Backups/%computername%/Test/"
So, as advised,
Code:If "%ComputerName%"=="FRED" Set ThisComputerName=Fred Synchronize Remote -Delete "F:\Test" "/Backups/%ThisComputerName%/Test/"
But, if you learn the For & Reg commands, you will also be able to use
Code:For /F "usebackq tokens=3 " %%X in (`Reg Query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters" /v HostName`) Do Set ThisComputerName=%%X Synchronize Remote -Delete "F:\Test" "/Backups/%ThisComputerName%/Test/"

Thanks.
Just to round things off -
Here are links to useful study materials for batch file scripting & PowerShell
Batch file, PowerShell guides - post #13 - TenForums
Manipulating variables in batch files - post #14 - TenForums
I believe that, if you are going to invest time & energy to study any form of scripting, then PowerShell is the one most likely to generate the biggest return on that investment.

Even better ... use bash shell under WSL.
Real Linux, on Windows.
Thanks, is there web to discuss when to apply PowerShell vs VBscript vs VBA?
Example of my dilemna:
PS is powerful but cryptic & Import-Modules isn't ez. VBscript isn't suitable as modules nor Class. VBA is being replaced by Java.
As a non-IT user, how to know when to use which.
My superiors equates lots-of-code-line to complexity and few line of codes is best.
I need some guidance if any! Thanks!
