I'm writing scripts to automate some task to be executed from windows machine to remote ubuntu server, which uses putty-tools like plink.exe, pscp.exe and psftp.exe.
My python program is able to run successfully but I'm trying to build a single independent standalone file which can be run in another PC even if that PC do not have these putty tools available.
I'm using below commands
python -m nuitka --enable-plugin=tk-inter --windows-disable-console --onefile --standalone my_program.py
I'also found related question here but it was not answered
Bundle third party .exe in Python code and produce another portable .exe
Can someone please help me on this.
Fortunately I found answer for my question by reading the nuitka user manual, we need to use one of the below format based on the requirement. In my case I used second one.
# This will find a file near your onefile.exe
open(os.path.join(os.path.dirname(sys.argv[0]), "user-provided-file.txt"))
# This will find a file inside your onefile.exe
open(os.path.join(os.path.dirname(__file__), "user-provided-file.txt"))
And while packing my command become something like below,here it will include all the files available in source directory to target directory in "onefile.exe"
python -m nuitka --enable-plugin=tk-inter --windows-disable-console --onefile
--include-data-dir=<source>=<target> --standalone my_program.py

I want to execute a Linux binary from a QT application running on W10.
In QT we have QProcess to launch additional processes. However, since my binary is for Linux, I've thought of two possible approaches:
Running the binary in a container (i.e.: Docker, Kubernetes, Singularity...).
Executing the binary through WSL (Ubuntu) bash.
In any case, the QT application should initiate the process (the container or the bash) and, in turn, this process should launch my binary.
I've been searching on the web and I could not find something related, what makes me think that it will be difficult. For this reason, I am posting the question in order to know the viability of the proposed approaches.
EDITED
It looks like the WSL is easier, the problem is that the user has to have install ed it. Apart from requiring the sudo password when installing new software via apt-get.
The binary that I have to execute only exists for Linux, and let's say that cross-compiling is dismissed because of its complexity. Furthermore, this application needs CGAL, BOOST, MPI, among other pieces of software.
If you want to go with WSL, you can just run wsl myLinuxProgram --options.
Using WSL is the easiest way I believe as the current directory (PWD), is the current one i.e. the same as the PWD of your Qt app.
You can read Microsoft documenation for more info: https://learn.microsoft.com/en-us/windows/wsl/interop
If your linux binary depends on a lots of things, I really suggest you use docker for windows. Then, you have chance to pre-build an own docker image which put all dependency software also the linux binary you need to run in it.
Of course, to let your customer to use it, you should put it to dockerhub, register an account for yourself.
Then, the solution is simple: let the QT application to call docker run to setup a container base on your own image, execute it, and also let the linux binary to write the log or others to the bind mount volume among linux container & windows. After it run, the QT application fetch the linux binary output from this shared folder.
Finally, I give a minimal workable example for your reference:
Suppose the shared folder between windows & linux container is: C:\\abc\\log_share, it will mapped to linux container as /tmp folder. Of course you need to allow volume share by right click the docker icon in windows tray area & choose settings, like described here
Simplify the windows application as bat file, and simplfy the docker image as ubuntu, you should use your own prebuilt docker image with all dependency in it:
win_app.bat:
ECHO OFF
::New a shared folder with linux container
RD /s/q C:\\abc\\log_share > NUL 2>&1
MKDIR C:\\abc\\log_share
::From windows call docker to execute linux command like 'echo'
echo "Start to run linux binary in docker container..."
docker run -it -v C:\\abc\\log_share:/tmp ubuntu:16.04 bash -c "echo 'helloworld' > /tmp/linux_log_here.txt"
::In windows, get the log from shared bind mount from linux
echo "Linux binary run finish, print the log generated by the container..."
type C:\\abc\\log_share\linux_log_here.txt
Simplify the linux binary just as echo command in linux, the output things should be all write to shared directory:
echo 'helloworld' > /tmp/linux_log_here.txt
Now, execute the bat file with command win_app.bat:
C:\abc>win_app.bat
C:\abc>ECHO OFF
"Start to run linux binary in docker container..."
"Linux binary run finish, print the log generated by the container..."
helloworld
You can see the windows application already could fetch things(here is helloworld) which generated by linux binary from docker container.
I am trying to install the pyperclip module for Python 3.6 on Windows (32 bit). I have looked at various documentations (Python documentation, pypi.python.org and online courses) and they all said the same thing.
1) Install and update pip
I downloaded get-pip.py from python.org and it ran immediately, so pip should be updated.
2) Use the command python -m pip install SomePackage
Okay here is where I'm having issues. Everywhere says to run this in the command line, or doesn't specify a place to run it.
I ran this in the command prompt: python -m pip install pyperclip. But I got the error message "'python' is not recognized as an internal or external command, operable program or batch file.
If I run it in Python 3.6, it says pip is an invalid syntax. Running it in IDLE gives me the same message.
I have no idea where else to run it. I have the pyperclip module in my python folder. It looks like a really simple problem, but I have been stuck on this for ages!
You need to add the location of the python.exe to your $PATH variable. This depends on your installation location. In my case it is C:\Anaconda3. The default is C:\Python as far as I know.
To edit your path variable you can do the following thing. Go to your Control Panel then search for system. You should see something like: "Edit the system environment variables". Click on this and then click on environment variables in the panel that opened. There you have a list of system variables. You should now look for the Path variable. Now click edit and add the Python path at the end. Make sure that you added a semicolon before adding the path to not mess with your previous configuration.
How am i able to execute UNIX commands on my PC Command prompt? Note i do not have cygwin installed, although i was going to before i discovered this.
This is a development machine so i have a lot installed on it like ruby, python, git, github, node and so on.
What does this mean? can i use this without cygwin?
Here is a list of programs installed on my PC program list
How am I able to execute UNIX commands on my PC Command prompt?
You can use the where command in a cmd shell to find out the exact location of your Unix commands, for example:
where ls
This assumes, of course, that ls is located somewhere in your current PATH.
The location returned will show you in which directory your Unix commands are installed and may be enough for you to determine how they were installed.
The where command is roughly equivalent to the Unix which command.
By default, the search is done in the current directory and in the
PATH.
Syntax
WHERE [/r Dir] [/q] [/f] [/t] Pattern ...
WHERE [/q] [/f] [/t] [$ENV:Pattern

Running Unix commands in windows can be done by having a tool like Cygwin which has those commands.
You can also get many of those commands compiled for windows and then run them using the command with the full path or only the command if the executable is in a path known by adding the paths to the executable files in Windows by :
1) Running in the terminal: PATH %PATH%;C:\<new_path>
2) Creating command aliases like: doskey np=C:\<new_path>\new_command.exe $*. $* is used to be able to transmit parameters
I am a newbie to UNIX, i want to print tree structure of files in a directory. below image is example in DOS, what will be the command of Unix to achieve same objective
I think you are looking for the "tree" command. If you are having issues running it you might have to find out how to install it on your specific distribution. For ubuntu installs you can find instructions here:
https://askubuntu.com/questions/507588/not-able-to-install-tree-comand-in-ubuntu
Not sure what you mean by "on Unix". What OS are you running, specifically? Tree should be compatible on Unix systems. You may just have to compile it for your particular OS.
This command prints output like the following (on cygwin):
I'm trying to build an application from source in windows that requires some Unix tools. I think it's the apparently standard ./configure; make; make install (there's no INSTALL file). First I tried MinGW but got confused that there was no bash, autoconf, m4, or automake exes in \bin. I'm sure I missed something obvious but I installed Cygwin anyways just to move forward. For some reason when I run
sh configure.sh
I get:
platform unix
compiler cc
configuration directory ./builds/unix
configuration rules ./builds/unix/unix.mk
My OS has identity problems. Obviously the makefile is all wrong since I'm not on unix but win32. Why would the configure script think this? I assume it has something to do with Cygwin but if I remove that I can't build it at all. Please help; I'm very confused.
Also is it possible to build using MinGW? What's the command for bash and is mingw32-make the same as make? I noticed they're different sizes.
Everything is fine. When you are inside CygWin, you are basically emulating an UNIX. sh runs inside CygWin, and thus identifies the OS correctly as Unix.
Have a look at GCW - The Gnu C compiler for Windows
Also, you might be interested in this help page, that goes into some detail about the minimal system (MSYS), such as how to install, configure et. c.
That should help you get bash, configure and the rest to work for MinGW as well.
From the Cygwin home page
Cygwin is a Linux-like environment for Windows. It consists of two parts:
A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
A collection of tools which provide Linux look and feel.
Since configure is using the Cygwin environment, it is interacting against the emulation layer and so it is just like it's working on a Unix environment.
Have you tried building the application and seeing if it works?
