I am trying to run a .run file in cygwin, but I always seem to get this error:
Unable to start '~.run': There is no application associated with the given file name extension.
I needed to be a superuser, so I tried using the command: cygstart --action=runas "$#"
I read somewhere that cygstart is for invoking registered Windows handler, so this may be the problem, but I am unsure. Is there any way that I can run my .run file as a superuser using cygwin?
Well, as has been said, no application is associated with .run files on your
system. So you can do that one of two ways
Call the file with the program, example
cygstart notepad.exe ~.run
Tell the registry what to do with unknown extensions
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Unknown]
#=""
[HKEY_CLASSES_ROOT\Unknown\shell\Open\command]
#="notepad.exe \"%1\""
This question is not related to Cygwin but rather to Windows. cygstart works the same as Windows' start. That means, if you use [cyg]start file.extension it works very similarly as if you double-click on that file in Windows Explorer.
Therefore if you configure Windows to do what you need when you double-click on your *.run file, cygstart will work fine too.
I think that easier is to use appropriate extension which Windows already knows. It depends on what you have inside your *.run file. If it's executable, use exe extension, if it's batch script, use cmd or bat, if it's JavaScript, use js etc.
If you use Linux or some derivation, you need to execute the .run file with an absolute path, even if you have already navigated to the appropriate directory containing the file. See here:

I am trying to install pumba from the OS release page. Once it is downloaded, I try running
pumba --help
It gives a command not found error.
Can anyone suggest what am I missing? The amd_64 file has all read, write and execute permissions.
If the name of the file is pumba_linux_amd64, you have to use that. Additionally, since the file is (assuming) not in your $PATH, you can't launch it directly.
If your file is in your current directory, run
./pumba_linux_amd64
Well the idea goes as followed,
I have a bash file for linux, there I obviously run it by making ./my_run.
The problem is I'm in windows so I downloaded and installed cygwin.
I added cygwin bin to the Enviromental Variables and check that at least "ls" works so I guessed I did it well.
When I try to run it with the cmd it displays:
'.' is not recognized as an internal or external command,
operable program or batch file.
As if the cygwin variables were not correctly installed (as I said I tried ls and works).
Then I tried it directly with cygwin and when doing the ./my_run I got it to work right.
So how is that I can use some commands like ls but when doing ./ it doesn't work on the cmd? How can I fix this?
Well, cygwin is only a shared library and a lot of stuff (the programs) using it (read Cygwin doc). cygwin.dll changes internally path resolution / chars to allow you to say ./my_script and converts it to .\my_script before doing the actual windows call, it also adds the proper extension to executables to allow it to execute windows binaries. This magic persists as long as you use it. cmd.exe is a Microsoft Windows command shell that is completely unaware of Cygwin's shared library and by that reason it doesn't use it, so it will not call it for path translation, even if you populate the environment of zetabytes of stuff. When you run in Cygwin terminal, you are running bash shell, which is a Cygwin executable, linked to cygwin.dll. It manages to use Cygwin library for all the unix system call emulations, so when you pass it e.g. to exec("./my_script", ...);, it internally converts that to try for ./my_script, then .\my_script, ./my_script.exe, ... and the same for .com and .bat extensions.
This fact often makes some people to say that Cygwin is not a good, efficient, environment. But the purpose was not to be efficient (and it is, as it caches entries and makes things best to be efficient) but to be compatible.
In your example ls is a Cygwin executable that mimics the /bin/ls executable from unix systems. It uses the Cygwin library, so all path resolution will be properly made (well, under some constraints, as you'll see after some testing) and everything will work fine. But you cannot pretend all your Windows applications to suddenly transform themselves and begin working as if they where in a different environment. This requires some try and error approach that you have to try yourself. And read Cygwin documentation, it is very good and covers everything I've said here.
If you open up Cygwin and run the command there you should be fine.
I was watching a speedy workflow tutorial about Atom text editor, and saw how the guy uses Linu commands like ls (to check the files in the directory), touch (to create files eg. style.css) and mkdir (to create folders). Now in my Atom editor I am able to open the command line using the following command.
CTRL + SHIFT + T
Now in my command line the default windows command line opens up, I am able to create folder using mkdir, but the commands touch and ls don't work, which makes me wonder weather Atom has its own command line?
See the SCREENSHOT to see how this guy is creating folders, files and using the ls command.
So my question is, how do I create files in Atom? How do I get the touch command to work?
It looks like the tutorial is using the Term2 package for opening a shell within the editor (http://code.tutsplus.com/courses/speedy-workflows-with-atom/lessons/term2). Since you seem to be able to open a terminal using the described screenshot, you seem to have the Term2 package installed - so far so good.
This package opens a standard command window within the editor. The tutorial seems to be using Linux or Mac OS X as the operating system. If you're running Windows, you will only have the Windows CMD interpreter available.
Windows does not natively support the touch command (but it has a mkdir command). There is a unxtools project that provides some of the common Gnu tools. If you install that, you should be able to run touch from the Windows command shell as well. More details can be found here.
I recently installed Cygwin on Windows 8.1, it works great but I can't execute file using the dot, for example "./hello.ml". I'm using the Windows's command prompt.
When I try using it, it show me that "." is not reconized. How can I make it works ?
Thanks.
You need to use the cygwin terminal or powershell instead.
The command interpreter doesn't think that your files are executable because they aren't one of the types that are recognized as binary executables. In general, Windows would use file associations from the registry to make things happen when you try to run a file. The cygwin terminal follows the unix-like convention and knows that your scripts are ml files and they are executable by using the ml interpreter, most likely from a #! at the top of your file.
im trying to install xampp on "new" linux mint machine.
However im quite a noob to linux since i havnt used it for that long.
When i try to run the file that ive download from the following page:
Xampp download
i get the following error two errors:
Could not display "/home/marc/Downloads/xampp-linux-x64-1.8.3-0-installer.run".
and if i click yes
Installing mime type handlers isn't supported
To search and install software which can open certain file types you have to install app-install-data.
can anyone tell me what the problem is and how i might fix it?
you need to execute the file (e.g. open a terminal, navigate to your Downloads folder and run bash xampp-linux-x64-1.8.3-0-installer.run (possibly it might need to be run otherwise, but thats my best guess)).
alternatively you might be presented to run/execute the file (instead of displaying it). if so, choose this option.
on the other hand, you might consider installing apache/php/mysql via your package manager.
what you can do is that you can use the chmod +x /your folder location/.run file that you want to install
after that you can run following command
./and your .run file name
example:-
in my case :- User#user~$su root
it will ask for password so give it
User#user~chmod +x /Downloads/xampp-linux-x64-1.8.3-0-installer.run
User#user~./xampp-linux-x64-1.8.3-0-installer.run
