I am taking a class in UNIX and have written a script that needs to countdown from a number that is read in from the keyboard to zero. If no number is given the start of the countdown should default to 10.
I can't get this to do the default

Hi guys, I've found two nifty little scripts on these forums one which detects if the F5 key has been pressed:
#/bin/sh
_key()
{
local kp
ESC=$'\e'
_KEY=
read -d '' -sn1 _KEY
case $_KEY in
"$ESC")
while read -d '' -sn1 -t1 kp
do
_KEY=$_KEY$kp

Hi all,
Does anyone know of any FUN countdown script that I can use for my script? At the moment, am just using sleep 10 or more and then print stuff into the screen to allow more time for the user to decide whether they want to continue running the script or abort?
Just thought of wanting... (3 Replies)
Hello, I have another problem with my script - I would like to have a countdown timer visible on the screen, and at the same time, I want te be able to do something else.

Net::DNS::SEC::Tools::TrustAnchor(3pm) User Contributed Perl Documentation Net::DNS::SEC::Tools::TrustAnchor(3pm)NAME
Net::DNS::SEC::Tools::TrustAnchor - base class for TA repositories
SYNOPSIS
This is a base class for multiple types of trustanchor repositories that know how to read, write, and modify trust anchor repositories.
This package serves as both a API wrapper around a set of trust anchors as well as a base class for packages that need to read/write trust
anchor sets into different formats.
Trust Anchors may be either DNSKEY records or DS references.
XXX: more documentation needed
API
Usage API defined by this module or sub-modules.
Note that:
use Net::DNS::SEC::Tools::TrustAnchor;
is assumed to have imported some of the API routines mentioned below.
$tar = new Net::DNS::SEC::Tools::TrustAnchor();
Initializes a new collection of trust anchors.
$module = load_module("type");
Dynamically attemps to load a TrustAnchor reader/writer sub-class of Net::DNS::SEC::Tools::TrustAnchor named "Type" and return an
instance of it.
All sub-classes are assumed to contain a single letter upper-case class name followed by all lower case. Any modules otherwise named
will fail to load using this routine.
$module = parse_component("type:file");
This parses a type and file specification consisting of type separated by a colon (':') followed by a file-name path. It will then
load the type module using the load_module() rotine and return the type, the file and extra options.
XXX: option parsing support not yet complete and will likely change the type:file format specification; I.E. the type:file formatting
specification will likely change in the future and should be considered alpha-level support.
$tar = $module->read($location, $options);
Reads in a given TAR from a $location reference and returns a blessed copy of the Net::DNS::SEC::Tools::TrustAnchor object containing
all the data.
This function may be over-ridden by a sub-class.
$tar = $module->read($location, $options);
Reads in a given TAR from a $location reference and returns an unblessed hash the contents. The read() function merely wraps around
this and blesses it after being returned.
Sub-modules must over-ride this function (and/or the read() function) if they expect the module to support loading.
$tar->merge(@others)
Merges the @other array of trust anchors into the $tar object's own trust anchor list.
