Скрипт IF EXIST

Помогите, пожалуйста написать скрипт по установке компонента Win7. Условие: если есть файл в директории, то запустить службу, если нет — запустить установку. Что-то начал воять, но даже не знаю на каком языке. Результата нет. Само собой, ведь программист из меня не оч) Заготовка:

IF EXIST — синтаксис
С чем может быть связано такое? Версия SQL server 2016. Microsoft SQL Server Management.

если ты админ или собираешься им стать,
то для подобных задач можно порекомендовать освоение Ansible
вместо ‘вояния’ на незнамо каком языке.

Решение

lacostewin, всё правильно.
Только переменную нужно раскрывать через знаки %
И скрипт запускать с повышенными привилегиями.
И немного поправить синтаксис.

How to verify if a file exists in a batch file?

I have to create a .BAT file that does this:

1. If C:\myprogram\sync\data.handler exists, exit;
2. If C:\myprogram\html\data.sql does not exist, exit;
3. In C:\myprogram\sync\ delete all files and folders except ( test , test3 and test2 )
4. Copy C:\myprogram\html\data.sql to C:\myprogram\sync\
5. 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 you do not need an «else», you can do something like this:

Here’s a working example of searching for a file or a folder:

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:

Here is a good example on how to do a command if a file does or does not exist:

We will take those three files and put it in a temporary place. After deleting the folder, it will restore those three files.

Use the XCOPY command:

I will explain what the /c /d /h /e /i /y means:

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

You are using a batch file. You mentioned earlier you have to create a .bat file to use this:

Batch program to to check if process exists

I want a batch program, which will check if the process notepad.exe exists.

if notepad.exe exists, it will end the process,

else the batch program will close itself.

Here is what I’ve done:

But it doesn’t work. What is the wrong in my code?

TASKLIST does not set errorlevel.

should do the job, since «:» should appear in TASKLIST output only if the task is NOT found, hence FIND will set the errorlevel to 0 for not found and 1 for found

taskkill /f /im «notepad.exe»

will kill a notepad task if it exists — it can do nothing if no notepad task exists, so you don’t really need to test — unless there’s something else you want to do. like perhaps

which would appear to do as you ask — kill the notepad process if it exists, then exit — otherwise continue with the batch

This is a one line solution.

It will run taskkill only if the process is really running otherwise it will just info that it is not running.

This is the output in case the process was running:

This is the output in case not running:

TASKLIST doesn’t set an exit code that you could check in a batch file. One workaround to checking the exit code could be parsing its standard output (which you are presently redirecting to NUL ). Apparently, if the process is found, TASKLIST will display its details, which include the image name too. Therefore, you could just use FIND or FINDSTR to check if the TASKLIST ‘s output contains the name you have specified in the request. Both FIND and FINDSTR set a non-null exit code if the search was unsuccessful. So, this would work:

There’s also an alternative that doesn’t involve TASKLIST at all. Unlike TASKLIST , TASKKILL does set an exit code. In particular, if it couldn’t terminate a process because it simply didn’t exist, it would set the exit code of 128. You could check for that code to perform your specific actions that you might need to perform in case the specified process didn’t exist:

That’s why it’s not working because you code something that is not right, that’s why it always exit and the script executer will read it as not operable batch file that prevent it to exit and stop so it must be

Create folder with batch but only if it doesn’t already exist

Can anybody tell me how to do the following in in a Windows batch script? ( *.bat ):

• Create a folder only if it doesn’t already exist

In more detail, I want to create a folder named VTS on the C:\ drive, but only if that folder doesn’t already exist. I don’t want to overwrite the contents of the folder if it already exists and the batch is executed.

You just use this: if not exist «C:\VTS\» mkdir C:\VTS it wll create a directory only if the folder does not exist.

Note that this existence test will return true only if VTS exists and is a directory. If it is not there, or is there as a file, the mkdir command will run, and should cause an error. You might want to check for whether VTS exists as a file as well.

Just call mkdir C:\VTS no matter what. It will simply report that the subdirectory already exists.

Edit: As others have noted, this does set the %ERRORLEVEL% if the folder already exists. If your batch (or any processes calling it) doesn’t care about the error level, this method works nicely. Since the question made no mention of avoiding the error level, this answer is perfectly valid. It fulfills the needs of creating the folder if it doesn’t exist, and it doesn’t overwrite the contents of an existing folder. Otherwise follow Martin Schapendonk’s answer.
