How to set file permission programmatically? I've created a compiler


Hi, I have written a simple back-end compiler for Linux x64 using Pascal which supports two commands only: ReadLine and WriteLine.

Now the issue is after my compiler generating the ELF64 binary program, I do not know how to set the file permission so that it can be allowed to execute.

In the mean time, I have to set each one manually:

--- Code: ---chmod u=rwx,g=rx,o=rx test
--- End code ---

BTW, if anyone is interested, can try this back-end compiler, open-source.
ELF64 binary file format is quite simple if used with only sys_read and sys_write.

If you had searched on chmod in the manuals, you would have found:
