Output Multiple Files in the For Loop
Code:
while IFS= read -r line
do
# sV for version detection
	nmap -T4 -Pn -v -sS "$line" > "text/$line"
done < <(grep '' $file)

Hi,
where
Code:
line

represents the IP.

I am using NMAP to do scanning.

How can I set to execute that command in the loop several concurrently at a time instead of one at a time.

xsetpointermapping

XSetPointerMapping(3X11)												  XSetPointerMapping(3X11)

NAME

       XSetPointerMapping, XGetPointerMapping - manipulate pointer settings

SYNOPSIS

       int XSetPointerMapping(display, map, nmap)
	       Display *display;
	       unsigned char map[];
	       int nmap;

       int XGetPointerMapping(display, map_return, nmap)
	       Display *display;
	       unsigned char map_return[];
	       int nmap;

ARGUMENTS

       Specifies  the  connection  to  the X server.  Specifies the mapping list.  Returns the mapping list.  Specifies the number of items in the
       mapping list.

DESCRIPTION

       The XSetPointerMapping function sets the mapping of the pointer. If it succeeds, the X server generates a MappingNotify	event,	and  XSet-
       PointerMapping returns MappingSuccess. Element map[i] defines the logical button number for the physical button i+1. The length of the list
       must be the same as XGetPointerMapping would return, or a BadValue error results. A zero element disables a button, and	elements  are  not
       restricted  in  value  by  the  number  of  physical buttons. However, no two elements can have the same nonzero value, or a BadValue error
       results. If any of the buttons to be altered are logically in the down state, XSetPointerMapping returns MappingBusy, and  the  mapping	is
       not changed.

       XSetPointerMapping can generate a BadValue error.

       The  XGetPointerMapping	function  returns  the current mapping of the pointer. Pointer buttons are numbered starting from one.	XGetPoint-
       erMapping returns the number of physical buttons actually on the pointer. The nominal mapping for a pointer is map[i]=i+1. The  nmap  argu-
       ment specifies the length of the array where the pointer mapping is returned, and only the first nmap elements are returned in map_return.

DIAGNOSTICS

       Some  numeric  value  falls  outside the range of values accepted by the request. Unless a specific range is specified for an argument, the
       full range defined by the argument's type is accepted.  Any argument defined as a set of alternatives can generate this error.
