Assume you are in your home directory, write the shell commands to perform the following tasks in sequential:

a. Run the command sleep 100 in background mode

b. List all processes with detailed information on the system

c. make a relative directory tree in the current directory adir/bdir/cdir (means creating adir as a subdir of current working directory, then create bdir inside adir, then cdir inside bdir)

d. move all files with the extension csv in current working directory to cdir
