I need to set up a long list of temporary environment variables every time when I start a Python Flask app on Windows 10. Now I would like to create a batch file to run with all settings in one double click. The following lines run well if I copy them and paste to cmd prompt, but I couldn't run them in the batch file.
The execution of batch file always gets tripped and exited at the 2nd line venv\scripts\activate in the batch file, which has no issue at all if I copy and paste line by line at cmd.
cd C:\py\project
venv\scripts\activate
set env1=val1
set env2=val2
set FLASK_APP=some.py
flask run
One of the many (far too many) quirks of .bat files is that if you launch another .bat file, it doesn't know where to return to.
You need to explicitly call it:
call venv\scripts\activate
you can just use
start venv\Scripts\activate
This will open up a new terminal just like that... you can pass other commands using the && or & sign.

I'm setting up an external hard drive with portable apps, and there are some CLI tools that I'd like to easily access.
I've done it before but I forgot how; basically, I have a file which sets the PATH variable for all the required CLI programs, and then allows me to use the command prompt normally.
How do I do this without having to run the file from another command prompt, but by double clicking the Batch file?
If your command line tools are in a folder named CLiTools next to the batch-file, then you could have 2 lines as the batch-file content.
#set "path=%path%;%~dp0CLiTools"
#cmd
You can double click the batch-file, it will open cmd with the modified setting of %path% and you can enter commands as you would normally do. If you have i.e. xyz.exe in the CLiTools folder, then you can type xyz at the current command prompt and will be recognized as a command.
The changed environment applies to the current child cmd session that inherited the environment.
%~dp0 is the drive and path of argument 0 which is the drive and path to the batch-file in this case.
I want to create an application in ionic from a batch file, executing commands from a file named appgenerator.bat.
I have created the batch file but commands aren't recognized.
It works correctly when I enter the command at the Command Prompt, but not inside the file.
appgenerator.bat:
#echo %off
set nombreAPP=nuevaAPP2
set path=C:\Users\Antonio
ionic start %path%\%nombreAPP% blank
And this is the screen in cmd.exe (first I put "ionic" to probe that the command works and after "appgenerator" to start with my batch file)
I dont think that the problem is in system environment variables, because in the cmd window, work correctly.
Currently this is how I have written the code in the batch file:
C:\ cd C:\abc\xyz\build-scripts-master
call setEnv.cmd
cmd ant do-clean
cmd ant do-dist
This is not working. It just executes the setEnv and breaks out. It does not run the remaining commands
Manually this is how it works:
I first go to the folder C:\abc\xyz\build-scripts-master through the Command Prompt
Then I type in setEnv, which is a windows command script, and hit return.
Then I type in ant do-clean
And then ant do-dist
I want to automate this process and hence was trying to achieve this using batch file.
Try the following:
#CD /D "C:\abc\xyz\build-scripts-master"
#Call setEnv.cmd
#Call ant.bat do-clean
#Call ant.bat do-dist
The latter two lines assume that ant.bat is located somewhere in the current working directory or %PATH%
It is not imperative that the directory path is doublequoted in this case, just good practice.You could continue not to use the .bat extension with ant. I've included it just to make it clear that it is a batch file, and should be Called in the same way as the setEnv batch file.
it didn't run the bat files because you didn't specify the files' location in the code. As it stands right now, the script expects the .bats to exist in the working directory or it has been placed in the folder. The only way it will run the files arbitrarily is if you had placed your working location in the system variables or set the Path to the folders location. I don't know if the cmd and call are needed. I have never used them in my scripts.
I have three different commands that I want to execute my running one script,
I created a file called as myscript.bat
I want the following two commands to run in sequence when I run the script:
cd C:\Users\johnDoe\Idea\View\Proxy
node proxy.js
PS:And after that I want the cmd to be left open, not close automatically
Leave the bat file as it is, but run it with cmd /k myscript.bat. Also, if there's a chance of the command window opening by default on another drive, you might want to add the line C: to the beginning of the script to change volumes. cd changes folders within a given volume, but it doesn't actually change volumes.
Alternatively, if you just want the window to stay open so you can read the output, but you don't actually want to run any additional commands in it after your commands finish, you can just add the line pause at the end of the script.
#reirab's answer contains the crucial pointer: use cmd /k to create a console window that stays open.
If you don't want to use cmd /k explicitly - say, because you want to open the batch file from Explorer, you have 2 options:
[Suboptimal] Add a cmd /k statement as the last statement to your batch file.
[Better] Write a wrapper batch file that invokes the target batch file with cmd /k.
For instance, if your batch file is startProxy.bat, create another batch file in the same folder, name it startProxyWrapper.bat, and assign the following content:
#cmd /k "%~dp0startProxy.bat"
When you then open startProxyWrapper.bat from Explorer, a persistent console window (one that stays open) will open and execute startProxy.bat.
Experts, I am trying to run a bat file using the below.
start /wait "D:|Silent_installer.bat"
start /wait 'D:def.bat"
It's happening like both bat files running at the same time.
But I wanted the first bat file to run completely then def.bat should start. The first bat file takes approx 60 min and inbetween second bat file starting.Ideally I wanted the first batch to complete 100% then second bat file should start.
I also used call like below but no luck
call "abc.bat"
call "def.bat"
Any suggestions would be of great help
You have to use start "" /wait command with the program in the abc.bat file itself. One of the programs being used inside abc.bat is multi-threaded and lets the batch file end before it finishes.
why not simply
"abc.bat"
"def.bat"
in your batch file ?
You could use Start command to start application
Ok. Two points here.
The start command is used for asynchronous execution, so if you " wanted the first batch to complete 100% then second bat file should start", just don't use it!
In order to execute two Batch files from inside another one, you must use call command as you show us in your question, that is:
.
call "abc.bat"
call "def.bat"
Perhaps if you explain what "I also used call like below but no luck" means, we may help you in a better way.
PS - Did you realized that your first example
"D:|Silent_installer.bat"
contain an invalid character | in the name of the Batch file?
