Using c language, write an initialization subroutine to set up inti as falling- edge triggered and int2 as rising-edge triggered interrupt inputs having high priorities. explain how you can find the source of the interrupt when an interrupt occurs. write the high priority interrupt subroutine (handler) that turns on the right led (pin 1 on porta) when the interrupt initialized in (a) is coming from inti and turns on the left led (pin 3 on porta) when it comes from int2.

Write the command that can be used to answer the following questions. (hint: try each out on the system to check your results.) a. find all files on the system that have the word test" as part of their filename. b. search the path variable for the pathname to the awk command. c. find all files in the /usr directory and subdirectories that are larger than 50 kilobytes in size. d. find all files in the /usr directory and subdirectories that are less than 70 kilobytes in size. e. find all files in the / directory and subdirectories that are symbolic links. f. find all files in the /var directory and subdirectories that were accessed less than 60 minutes ago. g. find all files in the /var directory and subdirectories that were accessed less than six days ago. h. find all files in the /home directory and subdirectories that are empty. i. find all files in the /etc directory and subdirectories that are owned by the group bin."
