REM stands for remark. It is strictly a comment and can not be executed. It keeps the programmer oriented.
Yes
the command to make anything executable is chmod +x <file>
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.
An internal command is a command built into the command interpreter (such as Command Prompt in Windows), allowing it to execute without needing a separate executable file. Examples include commands like COPY, DIR, and DEL. An external command, on the other hand, is a separate executable file (like .exe, .com, or .bat files) that the command interpreter can run, such as PING or FORMAT. If a command is not recognized, it may indicate that it is not an internal command or that the external command's executable file is not found in the system's PATH.
The command used to determine the path of an executable file in a Unix-like operating system is which. For example, running which python will return the path to the Python executable. In Windows, the equivalent command is where, such as where python.
ICON
chmod +x is the command to set the executable flag in Linux but, Linux does not use exe files.
Yes it is used to comment Dos line
Run program.exeorthe name of the program, with or without .exe (if the command prompt is in the same directory/folder of the executable)
"find / -executable" will search the root directory for executables. Not that this will also show directories that are accessible.
exe stands for Executable. FYI... com stands for command bat stands for batch
if the file is allready runnable you can type in the terminal: ./filename
