MOVING FILES AROUND

Here is another way to move
files around.

Sometimes you find yourself 
wanting to move a bunch of 
files into a new directory 
that is to be created in the 
current working directory. 

Rather than using a temporary 
directory, or grep and variable
substitution; use a subshell:

$ ( \ls; echo dir; mkdir dir ) | xargs mv

The trick is in using a subshell 
to run a number of commands 
_before_ the output is piped to 
xargs. This idiom is also useful 
for plenty of other applications.
