I have a query on this break. I am using a program where I am using a while loop to execute it. It will get into a file take the first file and then ping it and if the ip is reachable then it will mail. Now what happens is that when i ping the ip it does nopt come out of the loop and it says "reply from reply from" . I need to usse a break statemetn to come out of this. Can you assist me in this.

break(1T) Tcl Built-In Commands break(1T)
__________________________________________________________________________________________________________________________________________________
NAME
break - Abort looping command
SYNOPSIS
break
_________________________________________________________________
DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_BREAK code, which
causes a break exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command,
which then aborts its execution and returns normally. Break exceptions are also handled in a few other situations, such as the catch com-
mand, Tk event bindings, and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 5:
for {set x 0} {$x<10} {incr x} {
if {$x > 5} {
break
}
puts "x is $x"
}
