gcc hello.c -o hello ./hello

argc parte da 1 => argv[0] è il nome del programma stesso

int main(int argc, char* argv[]){ if(argc != 3){ printf("ERR! Usage: %s PID 8_CHAR_MSG\n", argv[0]); exit(EXIT_FAILURE); }

Python

`import sys import os import magic import subprocess

path = '.'

if (len(sys.argv) > 1): #get arguments with sys.argv path = sys.argv[1]

for (dirpath, dirnames, filenames) in os.walk(path): #how to access a path with os.walk if(dirpath == path): for file in filenames: #iterate through dir's files filep = (dirpath + '/' + file) if(os.access(filep, os.X_OK)): #check if a file is executable filetype = (magic.from_file(filep)) #get file type with magic lib if not ("ELF" in filetype): #check if a file is NOT an ELF subprocess.call(filep, shell=True) #exec script with subprocess lib `

How to check if you're the owner of the file: def ismine(path): return pwd.getpwuid(os.stat(path).st_uid).pw_name == os.getlogin()

Get time of last modify:

os.path.getmtime(path)
