159} How do I test that a name does not contain lowercase letters?
Let's limit the lowercase letters to the English alphabet a-z only.
@echo off & setlocal enableextensions
set name_=%~1
if "%name_%"=="" (
echo Usage: [NameToBeChecked]
goto :EOF
)
::
echo %name_%|findstr "[abcdefghijklmnopqrstuvwxyz]">nul
if %errorlevel% EQU 0 (
echo The name "%name_%" is not uppercase only
) else (
echo The name "%name_%" is uppercase only)
endlocal & goto :EOF
Examples of the output
C:\_D\TEST>cmdfaq "My Test File.txt"
The name "My Test File.txt" is not uppercase only
C:\_D\TEST>cmdfaq "MY TEST"
The name "MY TEST" is uppercase only
There is a catch in using findstr regular expressions. In the above
FINDSTR "[a-z]"
would not work as expected from the common regular
expressions definitions. The set option [a-z] seems to case
insensitive in the XP command line interface!
The central line of the task could be written in a "one-liner" style
as follows
@echo off & setlocal enableextensions
set name_=%~1
if "%name_%"=="" (
echo Usage: [NameToBeChecked]
goto :EOF)
::
echo %name_%|findstr "[abcdefghijklmnopqrstuvwxyz]">nul
&&echo Not upcase
||echo Upcase
endlocal & goto :EOF
Examples of the output
C:\_D\TEST>cmdfaq "My Test File.txt"
Not upcase
C:\_D\TEST>cmdfaq "MY TEST"
Upcase
Run the command following && only if the command preceding the symbol is successful.
Run the command following || only if the command preceding || fails.
What if we wish to list the UPPERCASE-only files in a folder?
@echo off & setlocal enableextensions
if "%~1"=="" (
echo Usage: "%~f0" "FolderName"
goto :EOF)
if not exist "%~1\" (
echo Folder "%~1" not found ^(or is a file^)
goto :EOF)
pushd "%~1\"
for /f "tokens=*" %%f in ('
dir /a:-d /b^|findstr /v "[abcdefghijklmnopqrstuvwxyz]"') do (
call :DisplayDateSizeName "%%~ff")
popd
endlocal & goto :EOF
::
:DisplayDateSizeName
set filename_="%~f1"
set filesize_= %~z1
set filesize_=%filesize_:~-10%
echo %~t1 %filesize_% "%~1"
goto :EOF
Part of the output could be e.g.
06.06.1998 06:18 334 "TESTADD.BAT"
04.06.1998 09:31 146 "TESTFNGT.BAS"
