Batch scenario: what is the difference between% 0 and% ~ f0?

Question

I have a script package in which I want to get the full path to the script. I am curious if there is a difference between this:

set scriptpath=%0

and this:

set scriptpath=%~f0

Thanks for the help.

Answer 1

%0 refer argument 0 - the name of the batch file - always exactly the same as specified on the command line or in another batch file.

So, if a batch file with the name Test.batstored in C:\Tempis launched, for example, from a command window with the current directory C:\c temp\test, then the link %0is replaced with temp\teston.

%~f0 - , 1 , &()[]{}^=;!'+,`~ .

Test.bat C:\Temp

@echo %0
@echo %~f0

"temp\test.bat" C:\:

"temp\test.bat"
C:\Temp\Test.bat

:

• ,
• .

%~f0 CALL call /? FOR for /? .
