Create exe file in linux

How to make a file executable in linux

A Unix kernel will need absolute path of an executable file in system call (see ). To obtain the absolute path of a file, the shell first looks up the command in directories specified in $PATH variable.

Build a Linux executable using GCC

That executable is a «Linux executable» — that is, it’s executable on any recent Linux system. You can rename the file to what you want using

rename a.out your-executable-name 

or better yet, tell GCC where to put its output file using

gcc -o your-executable-name your-source-file.c 

Keep in mind that before Linux systems will let you run the file, you may need to set its «executable bit»:

chmod +x your-executable-name 

Also remember that on Linux, the extension of the file has very little to do with what it actually is — your executable can be named something , something.out , or even something.exe , and as long as it’s produced by GCC and you do chmod +x on the file, you can run it as a Linux executable.

To create an executable called myprog , you can call gcc like this:

gcc -c -o myprog something.c 

You could also just rename the *.out file gcc generates to the desired name.

That is the executable. If you don’t like a.out , you can pass an -o flag to the compiler. If the executable isn’t marked with an executable bit, you need to do so yourself:

How can I create an executable in Linux (beginner)?

Initially, you need to write a shell script. Just open a text editor and write

Next, all you need to do is just to create a .desktop file in Ubuntu.

Open your terminal and type as

sudo -i cd /usr/share/applications/ nano

Then, it will give you an opened file and copy & paste these lines there one by one.

[Desktop Entry] Type=Application Terminal=true Name= Icon= Exec=

Save and close with CTRL+X+Y and hit Enter. You will have that script on your desktop as an application.

Like this, you can similarly create three applications for the three scripts you made.

Running executable files on Linux [duplicate]

Like any other program, a shell is also a program which is waiting for input. Now when you type in command1 arg1 arg2 . , the first thing a shell does is to try to identify command1 from among the following:

1. a function (try typeset -f in Bash shell)
2. an in-built command (such as type )
3. a shell alias (try alias in Bash shell)
4. a file that can be executed

Now the question concerns the last point a file that can be executed . A Unix kernel will need absolute path of an executable file in exec() system call (see man exec ).

To obtain the absolute path of a file, the shell first looks up the command in directories specified in $PATH variable.

So if you specify the relative path such as ../abc/command1 or ./command1 then Bash will be able to find that file and pass it to exec() system call.

If all the above four steps fail to locate the command1 input to the shell, you will get:

$ command1 command1: command not found 

However, if the file’s absolute path is resolved, but it is not executable, you get:

$ command1 bash: ./command1: Permission denied 

It means the current directory and the script is in the current directory.

The OS searches your $PATH when using a bare executable name ( foo vs ./foo ). In your case, the file may not reside on the path, so you need to tell the OS exactly where it is. You do that by specifying the path to the executable. That’s what the ./ i saying: look for the executable in my current working directory. It’s called a «relative path», and they’re handy for when the thing you want to reference is close to your current working directory.

Creating executable files in Linux

One thing I plan to be doing is writing (painfully simple) Perl scripts, and I’d like to be able to run them without explicitly calling Perl from the terminal. I appreciate that, to do this, I need to grant them execute permissions. Doing this with chmod is easy enough, but it also seems like a slightly laborious extra step. What I would like is one of two things: Firstly, is there a way to set the execute flag when saving a file? Currently I’m experimenting with gedit and geany, but would be willing to switch to a similarly- (or better-) featured editor if it had this capability. Failing that, is there a way to declare that all files created in a particular directory should have execute permissions? My umask is set to 022, which should be OK, as far as I understand, but it would appear that the files are created as text files (with 666 default permissions) rather than executable files (with 777 default permissions). Perhaps I’m just being lazy, but I figure there must be a more convenient way than chmodding every single script one creates.

You have to print the output of every file. You have to import the right libraries of every file. This seems like another step in the process of programming, and one that is dangerous to circumvent.

This should return something like

Then in the first line of your script add:

Then you can execute the file

There may be some issues with the PATH, so you may want to change that as well .

Thanks, but that’s not quite my problem. I’ve already gotten into the habit of starting my scripts with #!/usr/bin/perl. I can run scripts fine once I’ve given them executable permissions; I was just looking for a simpler way of doing so.

May I recommend #!/usr/bin/env perl instead? The env program basically finds the argument given (in this case, «perl») on the PATH and runs that. It’s useful when you’re sending scripts to other people — for example, I use a Mac, and Perl is located in /opt/local/bin.

No need to hack your editor, or switch editors.

Instead we can come up with a script to watch your development directories and chmod files as they’re created. This is what I’ve done in the attached bash script. You probably want to read through the comments and edit the ‘config’ section as fits your needs, then I would suggest putting it in your $HOME/bin/ directory and adding its execution to your $HOME/.login or similar file. Or you can just run it from the terminal.

This script does require inotifywait, which comes in the inotify-tools package on Ubuntu,

sudo apt-get install inotify-tools 

Suggestions/edits/improvements are welcome.

#!/usr/bin/env bash # --- usage --- # # Depends: 'inotifywait' available in inotify-tools on Ubuntu # # Edit the 'config' section below to reflect your working directory, WORK_DIR, # and your watched directories, WATCH_DIR.

Create executable application in linux

I wanna know how to create executable application in linux just like .exe file in windows. most of you have used/seen «Pidgin IM» in linux on click of that it will open the window where you can see your buddies and more similar to gnome-caculator. i want to create the same executable file for my application. thank you adavnce.

Could you further clarify your question? Is your question about wanting to know how to create a desktop/»Start menu» shortcut which the users could click on?

The most common way to create executables is to use a compiler. (Just like on windows.) The GNU Compiler Collection (GCC) may already be installed on your Linux system, see if you can find it with:

If not, you’ll have to install it. It has man pages ( man gcc ), info pages ( info gcc ), and an online manual.

Note the gcc command itself is the C compiler part, there’s g++ for C++ and others for other languages (though you have considerable control through command line options).

It sounds like you are looking for a framework such as Qt or WxWidgets. Both these frameworks allow you to create windowed GUI applications for Linux (and Windows and Mac OS X).

You first have to write your program. You could write it in C, C++, Python, Java, or anything. If you want the program to have a GUI, rather than just being command-line based, then you have to write code that paints windows, buttons, etc.

After doing that, you’ll have an executable. In Linux, in contrast to Windows, executable files don’t have a «.exe» suffix. Were you to open a terminal, you could just type in «pidgin» and the program would run.

Finally, to create the desktop/menu shortuct, that is specific to the GUI environment. In gnome, you can right-click on the desktop, select «Create Launcher», and follow the menu to select the executable file you have created — similarly to what you do in Windows.

Not sure if this is what you were asking about, but I hope that is helpful!
