DESCRIPTION

       This manual page documents the GNU version of xargs.  xargs reads arguments from the standard input, delimited by blanks (which can be pro-
       tected 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.

   OPTIONS
       --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 termi-
	      nate 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.

       --version
	      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.
