Question:
I have a .bat that is used to change names to .jpg files
The original file name is a 4 or 5 digit numeric code followed by a space and a string of alphanumeric characters. Such that:
1001 ASDFGJHJS.jpg
I have this code that renames them taking the first 5 characters.
for %%i in ("*.jpg") do (set fname=%%i) & call :rename
goto :eof
:rename
::Cuts off five chars, then appends .jpg
ren "%fname%" "%fname:~0,5%.jpg"
goto :eof
How do I detect the space so that it is the first 4 or 5 digits that I take?
Answer:
The solution I found was something simple that I hadn't tried:
IF "%fname:~4,1%"==" " (ren "%fname%" "%fname:~0,4%.jpg") else (ren "%fname%" "%fname:~0,5%.jpg")
With the IF "%fname:~4,1%"==" " I check the 5th character, if it is a blank space I take the first 4 characters, if it is not a space I take the first 5
