echo $arg | cut -c 1,2 | read remainArg or
echo $arg | cut -c 1,2 | read $remainArg
so that the result will be assign to remainArg.
Anyway to do this? :) (1 Reply)

tk_ownselection
Tk_OwnSelection(3) Tk Library Procedures Tk_OwnSelection(3)__________________________________________________________________________________________________________________________________________________NAME
Tk_OwnSelection - make a window the owner of the primary selection
SYNOPSIS
#include <tk.h>
Tk_OwnSelection(tkwin, selection, proc, clientData)
ARGUMENTS
Tk_Window tkwin (in) Window that is to become new selection owner.
Atom selection (in) The name of the selection to be owned, such as XA_PRIMARY.
Tk_LostSelProc *proc (in) Procedure to invoke when tkwin loses selection ownership later.
ClientData clientData (in) Arbitrary one-word value to pass to proc.
_________________________________________________________________DESCRIPTION
Tk_OwnSelection arranges for tkwin to become the new owner of the selection specified by the atom selection. After this call completes,
future requests for the selection will be directed to handlers created for tkwin using Tk_CreateSelHandler. When tkwin eventually loses
the selection ownership, proc will be invoked so that the window can clean itself up (e.g. by unhighlighting the selection). Proc should
have arguments and result that match the type Tk_LostSelProc:
typedef void Tk_LostSelProc(ClientData clientData);
The clientData parameter to proc is a copy of the clientData argument given to Tk_OwnSelection, and is usually a pointer to a data struc-
ture containing application-specific information about tkwin.
KEYWORDS
own, selection owner
