#Say you have a data file called datafile, e.g. containing some numerical data. You
#want to append the content of datafile to a file called targetfile. The shell script is:


cat datfile >> targetfile | cat targetfile


#The command '| cat targetfile' is optional. It means the screen will print out the content of targetfile
#right after the action of appending has been done to targerfile.

#Note that the file targetfile may not need to exist in the bigining. It will be created if it is 
#not in existence in the begining.
