Problem with temporary folder location in NodeJs Azure Function - node.js

In my function I'm writing something to a file.
The file path provided by me is d:/local/temp, as suggested in documentation.
The command successed and next in the same function I'm listing the directory content, the file is there.
But when I go via console or Kudu to d:/local/temp, it doesn't contain the content I created. I can confirm it with 'dir filename /s on D drive'
When I run the function again I still can list all previously generated files, so they didn't go
So the d:/local/temp in Kudu/console for the App function and the nodejs code is not the same path, but how I can find the real location of my files?

Please try to add an additional option /B or /b for the command dir <filename> /S to show the full path of a file, as below.
dir <filename> /S /B
# the result is like D:\<full-parent-path>\filename

Hard symbolic link: Specifiy "Start in:" and Parameters

I'm using
mklink /h "C:\Shortcut.exe" "C:\Real.exe"
to create a hard symbolic file link.
However, I don't see how I could specify the "Start in:" property for the Target file or parameters.
Is there a way to do that?
You can create Shortcut.bat (instead of a link) and write below command into it:
call "absolute\path\of\your\excecutable" %*
Example:
#call "C:\Program Files (x86)\GnuWin32\bin\openssl.exe" %*
Save above lines in openssl.bat everywhere you need a shortcut.

Search for a file and open the path in CMD

I would like to achieve the following in CMD:
Will search for a specific filename - This I know how to do, with dir /s filename
Once found it will bring me to that path.
Example: I am now on C:\, if that file was found in C:\test then it will open C:\test in command prompt.
Alternatively, I would like just to copy the found file to a path I will specify. I just don't know how to do it, since I don't know the path where the file will be stored (it's different every time).
Thanks in advance!
I'm a liitle confused with your question but I will try to walk you through a batch code I wrote to help you with this.
dir /b /s "test.txt" > "%userprofile%/Desktop/result.txt"
::find the file path to the file you want to find and insert it in a .txt file
::you made called result.txt (also %userprofile% is a variable that brings you to
::your user directory ex C:/users/admin)
for /F "tokens=*" %%A in (%userprofile%/desktop/result.txt) do (
set var1=%%A
)
::set the variable var1 equal to the first (well... only) line in the file.
::I could explain what that for loop means in detail but just remember that %%A
::is a variable set from what was found when looping through the result.txt.
xcopy /s "%var1%" "C:/wherever/you/want/it/to/go"
did this help??

Move 300 images from a folder (contains 800 images) to another based on file name list

I need to move 300 images from a folder (contains 800 images) to another folder. The file name list of these 300 images are available in the excel format. Is it possible to move them via programming instead of search the file and move it one by one? Our IT told me he can't separate these files. Do you have any solution? Many thanks in advance!!!
Here's one way of doing this - I am assuming you are on Windows. First, save text file called ListOfImages.txt that contains the names of the images you wish to move - put one image on each line and include the extension. Then, save the following into a file called movefiles.cmd:
#echo off
set Source=C:\Users\YourName\Desktop\moving\MovingFrom
set Target=C:\Users\YourName\Desktop\moving\MovingTo
set FileList=C:\Users\YourName\Desktop\moving\ListOfImages.txt
echo.
if not exist "%Source%" echo Source folder "%Source%" not found & goto Exit
if not exist "%FileList%" echo File list "%FileList%" not found & goto Exit
if not exist "%Target%" md "%Target%"
for /F "delims=" %%a in ('type "%FileList%"') do move "%Source%\%%a" "%Target%"
:Exit
echo.
echo press the Space Bar to close this window.
pause > nul
You will want to change the variables for Source, Target, and FileList to match where you have those folders and the ListOfImages.txt on your machine. After you have saved this file (make sure it has the .cmd extension, you should be able to double-click it and it will run the commands in your Command Prompt.
For example, say my MovingFrom folder contains the following:
And I only want to move Image1.png and Image2.png -- then my ListOfImages.txt file would like this:
After running moveFiles.cmd (provided I have changed the necessary variables to point to the right folders/places on my machine), my MovingTo folder should contain the following:
Notice that Image2.png was not moved because it was not listed in the ListOfImages.txt text file.

what is Batch file (.bat) equivalent for if [-f $path ] [duplicate]

I have to create a .BAT file that does this:
If C:\myprogram\sync\data.handler exists, exit;
If C:\myprogram\html\data.sql does not exist, exit;
In C:\myprogram\sync\ delete all files and folders except (test, test3 and test2)
Copy C:\myprogram\html\data.sql to C:\myprogram\sync\
Call other batch file with option sync.bat myprogram.ini.
If it was in the Bash environment it was easy for me, but I do not know how to test if a file or folder exists and if it is a file or folder.
You can use IF EXIST to check for a file:
IF EXIST "filename" (
REM Do one thing
) ELSE (
REM Do another thing
)
If you do not need an "else", you can do something like this:
set __myVariable=
IF EXIST "C:\folder with space\myfile.txt" set __myVariable=C:\folder with space\myfile.txt
IF EXIST "C:\some other folder with space\myfile.txt" set __myVariable=C:\some other folder with space\myfile.txt
set __myVariable=
Here's a working example of searching for a file or a folder:
REM setup
echo "some text" > filename
mkdir "foldername"
REM finds file
IF EXIST "filename" (
ECHO file filename exists
) ELSE (
ECHO file filename does not exist
)
REM does not find file
IF EXIST "filename2.txt" (
ECHO file filename2.txt exists
) ELSE (
ECHO file filename2.txt does not exist
)
REM folders must have a trailing backslash
REM finds folder
IF EXIST "foldername\" (
ECHO folder foldername exists
) ELSE (
ECHO folder foldername does not exist
)
REM does not find folder
IF EXIST "filename\" (
ECHO folder filename exists
) ELSE (
ECHO folder filename does not exist
)
Here is a good example on how to do a command if a file does or does not exist:
if exist C:\myprogram\sync\data.handler echo Now Exiting && Exit
if not exist C:\myprogram\html\data.sql Exit
We will take those three files and put it in a temporary place. After deleting the folder, it will restore those three files.
xcopy "test" "C:\temp"
xcopy "test2" "C:\temp"
del C:\myprogram\sync\
xcopy "C:\temp" "test"
xcopy "C:\temp" "test2"
del "c:\temp"
Use the XCOPY command:
xcopy "C:\myprogram\html\data.sql" /c /d /h /e /i /y "C:\myprogram\sync\"
I will explain what the /c /d /h /e /i /y means:
/C Continues copying even if errors occur.
/D:m-d-y Copies files changed on or after the specified date.
If no date is given, copies only those files whose
source time is newer than the destination time.
/H Copies hidden and system files also.
/E Copies directories and subdirectories, including empty ones.
Same as /S /E. May be used to modify /T.
/T Creates directory structure, but does not copy files. Does not
include empty directories or subdirectories. /T /E includes
/I If destination does not exist and copying more than one file,
assumes that destination must be a directory.
/Y Suppresses prompting to confirm you want to overwrite an
existing destination file.
`To see all the commands type`xcopy /? in cmd
Call other batch file with option sync.bat myprogram.ini.
I am not sure what you mean by this, but if you just want to open both of these files you just put the path of the file like
Path/sync.bat
Path/myprogram.ini
If it was in the Bash environment it was easy for me, but I do not
know how to test if a file or folder exists and if it is a file or
folder.
You are using a batch file. You mentioned earlier you have to create a .bat file to use this:
I have to create a .BAT file that does this:
Type IF /? to get help about if, it clearly explains how to use IF EXIST.
To delete a complete tree except some folders, see the answer of this question: Windows batch script to delete everything in a folder except one
Finally copying just means calling COPY and calling another bat file can be done like this:
MYOTHERBATFILE.BAT sync.bat myprogram.ini

How to set a string from a txt to a variable with cmd

I have a txt file to a specific path that contains one or more line just like
the following:
Directory of c:\folderA\folderB
Directory of c:\folderC\folderD
these are the paths of a program example.exe. I want automatically to find the path that example.exe exists in my computer and to run it from a .cmd script. So far i have succeed to log the paths of existence to a txt. How can I set a variable with only the path of
the first line?
The final result should be var_path=c:\folderA\folderB
A quick and dirty solution is:
#echo off
Call :getFirstDirectory
::do your stuff with %var_path%. For example:
#echo %var_path%
exit /b
:getFirstDirectory
for /f "tokens=3" %%a in (dirs.txt) do (
set var_path=%%a
exit /b
)
Which assumes that dirs.txt is the file containing:
Directory of c:\folderA\folderB
Directory of c:\folderC\folderD
