.SH NAME
xargs \- constuct argument list(s) and execute command
.SH SYNOPSIS
.B xargs
.RB [ \-r ]
.RI [ cmd
.RI [arg... ] ]
.SH DESCRIPTION
xargs reads space, tab, newline and EOF delimited strings from stdin
and executes the specified cmd with the strings as arguments.
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.
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.
.SH OPTIONS
.TP
.BI \-r
Do not run the command if there are no arguments. Normally the command is
executed at least once even if there are no arguments.
