mkdir creates file instead of directory ...

[Joe HM]

Hello -

I have this strange intermittent problem where a mkdir command in a
batch file will create a file with the name of a directory instead of
the directory itself. This has happened for several people and I have
no clue what is causing it.

Here is the code ...

if not exist "C:\Program Files\X" mkdir "C:\Program Files\X"
if not %ERRORLEVEL% == 0 goto error
if not exist "C:\Program Files\X\Y" mkdir "C:\Program Files\X\Y"
if not %ERRORLEVEL% == 0 goto error

Could this be because I am creating two directories or is this a bug
with mkdir?

I/we have XP SP2.

Thanks,
Joe

The probability of there being a bug with mkdir is extremely small.
It is far more likely that you created a file called "mkdir.bat", which
is not a good idea. What happens if you replace the command
"mkdir" with its alias "md"?

By the way, you could tighten your code like so:
if not exist "C:\Program Files\X" md "C:\Program Files\X" || goto error
if not exist "C:\Program Files\X\Y" md "C:\Program Files\X\Y" || goto error

Hello -

The batch file is called INSTALL.XXX.bat and not mkdir.bat.

I will try the md ... what is the difference? Is the || always
equivalent to if not %errorlevel% == 0?

Thanks a lot!

====================

I did not say that your batch file is called mkdir.bat. I suggested that
you have a file mkdir.bat (or mkdir.cmd) hanging about, perhaps from
a previous exercise.

The || connector executes the command following it if the preceding
command returns an error level > 0. Its twin brother is the && connector.

Hello -

I see ... I searched my machine and found a mkdir.exe in C:\cygwin
\bin. I think this is somewhere at the end of my path so it should
not be executed. I have actually not seen the problem on my own
machine but on other people's machines. They do not have Cygwin
installed ... why would the mkdir.exe help???

What is the && doing? I assume it is not an "and" since I have
unsuccessfully tried to find such a thing ...

Thanks!
Joe

You need to search the other machines for mkdir.*

A quick test would show you that the || connector detects
ErrorLevel > 0 whereas its twin && detects ErrorLevel = 0 . . .

mkdir (or its synonym "md") belongs to the class of commands such as copy,
cd, rd or del that are internal to the Command Processor cmd.exe.

oh fine so , internal commands can't be found inside our system?????

They exist as commands but the do not have files associated with them.

internal commands are not separate files. At the command prompt type Help MD
