Trying to interpret your description of your script's behaviour, I'd infer that /home/Rvtools/test.csv exists from the beginning and the while loop is not entered at all. Run your script with the xtrace (-x) option set, and, if you're still stuck, post the output here for further analysis.
Be aware that the cp command fails with cp: target 'YY' is not a directory if multiple *.csv source files exist.
Be aware that the exec command "replaces the shell. No new process is created." (c.f. man bash). Execution won't come back to your above scipt to finish the while loop and execute any eventual further code after the loop.
You might want to check your logics within the while loop, as - once the condition is true - nothing happens in the loop to modify that. Are you waiting for a background process to make that file appear somehow?

continue
continue(3tcl) Tcl Built-In Commands continue(3tcl)
__________________________________________________________________________________________________________________________________________________
NAME
continue - Skip to the next iteration of a loop
SYNOPSIS
continue
_________________________________________________________________
DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code,
which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop
command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as
the catch command and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 10 except 5:
for {set x 0} {$x<10} {incr x} {
if {$x == 5} {
continue
}
puts "x is $x"
}
