The original sbase implementation of

-supported multiple input-file arguments,
-as e.g. cat and grep do.
-Unfortunately, POSIX uniq treats its second argument (if present)
-as an output filename and clobbers it.
-Since users and scripts which rely on uniq
-supporting multiple input-file arguments
-would be at risk of data loss
-if they ever ran into a POSIX-compatible uniq,
-support for multiple input-file arguments
-was removed from this implementation.

+.Sh DESCRIPTION
xargs reads space, tab, newline and EOF delimited strings from stdin
and executes the specified cmd with the strings as arguments.
-
+.Pp
Any arguments specified on the command line are given to the command upon
each invocation, followed by some number of the arguments read from
stdin. The command is repeatedly executed one or more times until stdin
is exhausted.
-
+.Pp
Spaces, tabs and newlines may be embedded in arguments using single (`'')
or double (`"') quotes or backslashes ('\\'). Single quotes escape all
non-single quote characters, excluding newlines, up to the matching single
quote. Double quotes escape all non-double quote characters, excluding
newlines, up to the matching double quote. Any single character, including
newlines, may be escaped by a backslash.
