I want to have a batch file which checks what the filesize is of a file.
If it is bigger than %somany% kbytes, it should redirect with GOTO to somewhere else.
Example:
[check for filesize]
IF %file% [filesize thing Bigger than] GOTO No
echo Great! Your filesize is smaller than %somany% kbytes.
pause
exit
:no
echo Um... You have a big filesize.
pause
exit
If the file name is used as a parameter to the batch file, all you need is %~z1 (1 means first parameter)
If the file name is not a parameter, you can do something like:
@echo off
setlocal
set file="test.cmd"
set maxbytesize=1000
FOR /F "usebackq" %%A IN ('%file%') DO set size=%%~zA
if %size% LSS %maxbytesize% (
echo.File is ^< %maxbytesize% bytes
) ELSE (
echo.File is ^>= %maxbytesize% bytes
)
%~z1 expands to the size of the first argument to the batch file. See
C:\> call /?
and
C:\> if /?
Simple example:
@ECHO OFF
SET SIZELIMIT=1000
SET FILESIZE=%~z1
IF %FILESIZE% GTR %SIZELIMIT% Goto No
ECHO Great! Your filesize is smaller than %SIZELIMIT% kbytes.
PAUSE
GOTO :EOF
:No
ECHO Um ... You have a big filesize.
PAUSE
GOTO :EOF
If your %file% is an input parameter, you may use %~zN, where N is the number of the parameter.
E.g. a test.bat containing
@echo %~z1
Will display the size of the first parameter, so if you use "test myFile.txt" it will display the size of the corresponding file.
As usual, VBScript is available for you to use.....
Set objFS = CreateObject("Scripting.FileSystemObject")
Set wshArgs = WScript.Arguments
strFile = wshArgs(0)
WScript.Echo objFS.GetFile(strFile).Size & " bytes"
Save as filesize.vbs and enter on the command-line:
C:\test>cscript /nologo filesize.vbs file.txt
79 bytes
Use a for loop (in batch) to get the return result.
After a few "try and test" iterations I've found a way (still not present here) to get size of file in cycle variable (not a command line parameter):
for %%i in (*.txt) do (
echo %%~z%i
)
You'll need two things.
filesize.bat
@echo off
echo %~z1
And then what you're actually trying to size up.
Copy a file only if it's larger than zero / copy only a non-zero file
for /f %i in ('filesize filesize.bat') do set z=%i
if %z% gtr 0 ( copy filesize.bat noodles.bat )
I found this thread and it was almost what I needed, I tried a bunch of different things - this was mildly frustrating because robocopy looked to have /min:1 but got ALL bunged up because I wanted to rename the file in transit which made me have to use @#$!! batch script.
Just an idea:
You may get the filesize by running command "dir":
>dir thing
Then again it returns so many things.
Maybe you can get it from there if you look for it.
But I am not sure.
