REPETITIVE TASKS WITH XARGS

Save yourself a lot of typing when you have to perform repetitive
commands on a list of files. Put the list of files in a text file
with one file per line ie: find . -name version.C > filename
Then have xargs build a command line for each file in the list as
follows:

cat filename |xargs -n 1 cp anotherfile

This will copy anotherfile over all the files listed in
filename one at a time until the end of filename is reached.
