Hi,
I try to handle very large numbers with a bash script. I run ssh command in a remote server and store the output in a local variable. But this output contains a return carriage at the end.

update
update(n) Tcl Built-In Commands update(n)
__________________________________________________________________________________________________________________________________________________NAME
update - Process pending events and idle callbacks
SYNOPSIS
update ?idletasks?
_________________________________________________________________DESCRIPTION
This command is used to bring the application "up to date" by entering the event loop repeatedly until all pending events (including idle
callbacks) have been processed.
If the idletasks keyword is specified as an argument to the command, then no new events or errors are processed; only idle callbacks are
invoked. This causes operations that are normally deferred, such as display updates and window layout calculations, to be performed imme-
diately.
The update idletasks command is useful in scripts where changes have been made to the application's state and you want those changes to
appear on the display immediately, rather than waiting for the script to complete. Most display updates are performed as idle callbacks,
so update idletasks will cause them to run. However, there are some kinds of updates that only happen in response to events, such as those
triggered by window size changes; these updates will not occur in update idletasks.
The update command with no options is useful in scripts where you are performing a long-running computation but you still want the applica-
tion to respond to events such as user interactions; if you occasionally call update then user input will be processed during the next
call to update.
EXAMPLE
Run computations for about a second and then finish:
set x 1000
set done 0
after 1000 set done 1
while {!$done} {
# A very silly example!
set x [expr {log($x) ** 2.8}]
# Test to see if our time-limit has been hit. This would
# also give a chance for serving network sockets and, if
# the Tk package is loaded, updating a user interface.
