Batch - Converting variable to uppercase

Question

How would I go about changing the destl variable to uppercase before it is used. I assume some sort of character swap, however I couldn\'t get it working. C

Answer 1

If you have any POSIX utilities installed on Windows, like many developers (e.g., GNUWin utilities at https://sourceforge.net/projects/gnuwin32/)

You could use the tr.exe utility, which has: [:upper:]

@echo off
SETLOCAL EnableDelayedExpansion
echo Before: SCEINST is: %SCEINST%
set upper=
for /f "usebackq delims=" %%g in (`echo %SCEINST% ^| tr [:lower:] [:upper:]`) do (
    SET upper=%%g
    :: get rid of any leading whitespace
    set upper=!upper: =!
    goto :done
)
:done
echo After: SCEINST (in upper) is now: !upper!

----------OUTPUT----------

Before: SCEINST is: scprd
After: SCEINST (in upper) is now: SCPRD
