xargs is part of the "find" package. Arg list too long comes from the
kernel settings and can't be easily changed. xargs takes __words__ on
standard input and makes them arguments and passes then to as many
invocations of the program as needed.

In this case, then perl -pi... will probably be invoked about 30 times
with roughly 2000 args each time (unless the filenames are long, then
more invocations with fewer args each).
