mkdir creates file instead of directory ...

[Guest 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.

Re: mkdir creates file instead of directory ...

 

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

Re: mkdir creates file instead of directory ...

 

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 . . .
