But most of the people suggested to write a daemon in C language, which is alien to me(I have learnt C language some 9 years back but now totally forgot it 🙁 ). Here is one such link which will describe you how to create a daemon in Linux using C programming. http://www.netzmafia.de/skripten/unix/linux-daemon-howto.html. I went through many documentations and other stuff but come to a conclusion to go with Shell script. Which will work same as daemon. Here is the code for the daemon which we accomplish using while loop while true; do if [ -f /testing/*.txt ] then echo “file created” mv /testing/*.txt /tst/ fi done This while loop continuously runs because we give...
