echo %0 does not display extension (.cmd)

[miskox]

I have a strange situation:

User runs a .cmd from command prompt and receives an error (findstr command to search within %0):

batch_filename.cmd:

Code: Select all

FINDSTR: Cannot open batch_filename  <----- note there is no extension displayed

I checked my computer and in the system settings I have 'File name extensions' checked (open File Explorer -> View -> File name extensions). I played with this and if I run a .cmd (@echo %0&pause) it displays extension regardless of this settings. From command prompt it does not work after I changed settings (and even if I enable it again) (I cannot reboot the computer at the moment to see the result).

I use this FINDSTR within a FOR statement so I thought that this might have something to do with this (because new CMD.EXE is executed and would default to another working direcotory) - if this would be the case @echo %0 (not used within FOR) would work always.

Ideas?

Update: I created another .cmd in a way that FINDSTR command writes to a temporary file which is then read by FOR. When users makes a test I will write an update to this post.

Thanks.

Why do you expect that %0 contains the file extension? It only contains the own call. That is, if the script was called without file extension, %0 would never expand to something with file extension as long as you don't use the typical modifiers.

test.cmd on my desktop:

Code: Select all

@echo off
echo %0
echo "%~f0"
echo ~~~~~~~~~~~~~~

CMD prompt with the desktop being the current workdir:

Code: Select all

Thanks. You know there has always been something like "%0 is a batch file itself."

I never encountered this 'problem' because I always use full filename (I use TAB key).

test.cmd

Code: Select all

@echo %0
@echo %~x0

When run as 'test' only:

Code: Select all

C:\>test
test
.cmd

and when run as 'test.cmd':

Code: Select all

C:\>test.cmd
test.cmd
.cmd

So my FINDSTR command should be something like:

Code: Select all

findstr /B /C:"something" %~f0

instead of

Code: Select all

findstr /B /C:"something" %0

Thanks.
