       This manual page documents the GNU version of xargs.  xargs reads
       arguments from the standard input, delimited by blanks (which can be
       protected with double or single quotes or a backslash) or newlines, and
       executes the command (default is /bin/echo) one or more times with any
       initial-arguments followed by arguments read from standard input.
       Blank lines on the standard input are ignored.

       xargs exits with the following status:
       0 if it succeeds
       123 if any invocation of the command exited with status 1-125
       124 if the command exited with status 255
       125 if the command is killed by a signal
       126 if the command cannot be run
       127 if the command is not found
       1 if some other error occurred.

       --null, -0
              Input filenames are terminated by a null character instead of by
              whitespace, and the quotes and backslash are not special (every
              character is taken literally).  Disables the end of file string,
              which is treated like any other argument.  Useful when arguments
              might contain white space, quote marks, or backslashes.  The GNU
              find -print0 option produces input suitable for this mode.

       --eof[=eof-str], -e[eof-str]
              Set the end of file string to eof-str.  If the end of file
              string occurs as a line of input, the rest of the input is
              ignored.  If eof-str is omitted, there is no end of file string.
              If this option is not given, the end of file string defaults to

       --help Print a summary of the options to xargs and exit.

       --replace[=replace-str], -i[replace-str]
              Replace occurences of replace-str in the initial arguments with
              names read from standard input.  Also, unquoted blanks do not
              terminate arguments.  If replace-str is omitted, it defaults to
              "{}" (like for `find -exec').  Implies -x and -l 1.

       --max-lines[=max-lines], -l[max-lines]
              Use at most max-lines nonblank input lines per command line;
              max-lines defaults to 1 if omitted.  Trailing blanks cause an
              input line to be logically continued on the next input line.
              Implies -x.

       --max-args=max-args, -n max-args
              Use at most max-args arguments per command line.  Fewer than
              max-args arguments will be used if the size (see the -s option)
              is exceeded, unless the -x option is given, in which case xargs
              will exit.

       --interactive, -p
              Prompt the user about whether to run each command line and read
              a line from the terminal.  Only run the command line if the
              response starts with `y' or `Y'.  Implies -t.

       --no-run-if-empty, -r
              If the standard input does not contain any nonblanks, do not run
              the command.  Normally, the command is run once even if there is
              no input.

       --max-chars=max-chars, -s max-chars
              Use at most max-chars characters per command line, including the
              command and initial arguments and the terminating nulls at the
              ends of the argument strings.  The default is as large as
              possible, up to 20k characters.

       --verbose, -t
              Print the command line on the standard error output before
              executing it.

              Print the version number of xargs and exit.

       --exit, -x
              Exit if the size (see the -s option) is exceeded.

       --max-procs=max-procs, -P max-procs
              Run up to max-procs processes at a time; the default is 1.  If
              max-procs is 0, xargs will run as many processes as possible at
              a time.  Use the -n option with -P; otherwise chances are that
              only one exec will be done.
