executable

I wonder if I could write a program in the C -programming language that is executable, albeit not using a single library call, e.g. not even exit()? If so, it obviously wouldn't depend on libraries (libc, ld-linux) at all. I suspect you could write such a thing, but it would need to have an endless loop at the end, because you can't ask the operation system to exit your process. And you couldn't do anything useful. Well start with compiling an ELF program, look into the ELF spec and craft together the header, the program segments and the other parts you need for a program. The kernel would

I had a small python script that takes input from the command line arguments and done some operations using the inputs taken and display the result Below is the working example code some_file.py import sys arguments = sys.argv first_name = sys.argv[1] second_name = sys.argv[2] print "Hello {0} {1} !!!!".format(first_name,second_name) Now i am executing this as python some_file.py Steve jobs Result : Hello Steve Jobs !!!! Now what all i want is, i don't want to use python command before file name and extension of python file name, that is i want to run the file as a command tool as below some

Compilation using gcc -s and Unix strip remove all symbol table and relocation information from an executable (making it smaller in size). Could this ever affect the functioning of the executable? Do some operating systems which perform ASLR need this information? If not, why keep them around in the first place? A slightly- detailed overview of the above would be helpful. It seems pretty clear that removing relocation information would interfere with ASLR. However, I've taken a look at man strip on a couple of my systems, and none of them suggest that strip does (or indeed can?) remove

There appear to be some similar-looking long alphanumeric strings that commonly occur in Mach-O 64 bit executables and ELF 64-bit LSB executables among other symbols that are not alphanumeric: cat /bin/bash | grep -c "AWAVAUATSH" has 181 results, and cat /usr/bin/gzip | grep -c "AWAVAUATSH" has 9 results. What are these strings? Interesting question. Since I didn't know the answer, here are the steps I took to figure it out: Where in the file does the string occur? strings -otx /bin/gzip | grep AWAVAUATUSH 35e0 AWAVAUATUSH 69a0 AWAVAUATUSH 7920 AWAVAUATUSH 8900 AWAVAUATUSH 92a0 AWAVAUATUSH

I'm writing a small chrome extension for personal use and I would like to run an executable via the context menu and pass certain information as arguments to said executable. What the simplest and/or cleanest way to achieve this? To me it seems that it is impossible due to chrome's sandboxing. JSuar This can be accomplished via NPAPI Plugins . Code running in an NPAPI plugin has the full permissions of the current user and is not sandboxed or shielded from malicious input by Google Chrome in any way. You should be especially cautious when processing input from untrusted sources, such as when
