xargs is a command useful for acting upon the output of an earlier command; for instance, you could pipe the output of the find command to xargs rm to recursively delete all .tmp files below the current directory:
server# find . -name "*.tmp" | xargs rm
from the manpage:
The xargs utility reads space, tab, newline and end-of-file delimited
strings from the standard input and executes utility with the strings as
arguments.
Any arguments specified on the command line are given to utility upon
each invocation, followed by some number of the arguments read from the
standard input of xargs. The utility is repeatedly executed until stan-
dard input is exhausted.
