Open a terminal, browse to the directory where the files are, and run the command "ls -l". On the left-most side there will read something that looks like -rwx-. "r" means readable, "w" means writable, and "x" means that the file is executable. If the "x" is not there, then the file is not executable.
chmod +x is the command to set the executable flag in Linux but, Linux does not use exe files.
In general you do not. Nearly all executable files are coded in a computer programming language, and then compiled into executable files. So to modify an executable, you would need the source code for the program, you would modify the source code and then recompile into a NEW version of the executable. Linux does provide for an executable script file, but these are more scripts than executable files.
The cp command does that.
Executable means that the file has a series of instructions used to execute a program. Non-executable files are ones that do not have these instructions.
Executable files usually contain a header, which identifies it as an executable file, and a list of commands to be executed by the processor.
Check for the executable permission. ls -l will tell you the precise permissions of a file. On the very end of the permissions string, an executable will have an x there. Linux does not determine things like executability the same way Windows does. While Windows will happily (And blindly.) treat a file as an executable when it has certain file extensions, Linux thinks instead about two things: Whether it has a certain permission to run, and if its "interpreter" is available. Yes, even precompiled binaries run this way. In their case their "interpeter" is merely the loader that passes the program to the kernel for launch. There is a way to run scripts in Linux without the execute permission, and that's by invoking their interpreter directly yourself, such as the command: $ python2 /path/to/python/program.py In this case to Linux you're merely running python with the program you want as an argument. This does NOT work for precompiled binaries, which MUST be given executable permissions to load and run.
If it's already in your PATH variable, then simply the name of the executable would do. If not, then use the full path of the executable or navigate to the directory of the executable and then ./executable where "executable" is the name of the executable.
difference between executable file and non-executable file in dos
They're .exe files
The main Excel program file (excel.exe) is an executable file, but the workbooks it creates are not executable files.
Files with an extension of .exe are executable files. This type of file is one which is used to open applications games etc. it is the main file for each program. For example to open Internet Explore when you doubel click on the icon it actually make the ie.exe file open up and this gives you the internet explorer window.
the command to make anything executable is chmod +x <file>
