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
#! /bin/sh
echo Enter a number here to countdown... (2 Replies)
I am looking for a way to display on a single line, a running countdown for a given amount of time in a terminal using a bash script.
I am looking for this to use as part of a larger bash script that captures Video. The script sets up a bunch of parameters for DVgrab, and one of the parameters... (11 Replies)
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. And when the time runs out, I need to know about that inside the script somehow and do some action. I guess that would require 2... (3 Replies)

Hello. I am pretty new to unix and shell scripting and I was wondering if there might be a way to banner a countdown timer inside a script. We currently have an existing script that does a 2 minute sleep but thought it might be fun to actually make it banner a countdown timer until it is finished.... (3 Replies)

shevek::relative_time -
Time interval.
SYNOPSIS
#include <time.hh>
Public Member Functions
relative_time ()
The default constructor creates an interval of 0.
relative_time (timetype days, int hours, int minutes, int seconds, int nanoseconds=0)
Construct an interval of a given size.
relative_time (timetype seconds, unsigned nanoseconds)
Fast constructor.
relative_time operator+ (relative_time that) const
Add two intervals.
absolute_time operator+ (absolute_time that) const
Add an interval to a moment.
relative_time operator- (relative_time that) const
Subtract two intervals.
relative_time operator- () const
Negate an interval.
relative_time operator* (float c) const
Scale an interval.
relative_time operator/ (float c) const
Scale an interval.
relative_time operator% (relative_time that) const
Modulo operator for two intervals.
double operator/ (relative_time that) const
Division of two intervals.
relative_time & operator+= (relative_time that)
Add an interval.
relative_time & operator-= (relative_time that)
Subtract an interval.
relative_time & operator*= (float c)
Scale the interval.
relative_time & operator/= (float c)
Scale the interval.
relative_time & operator%= (relative_time that)
Modulo.
bool operator< (relative_time that) const
Compare with another interval.
bool operator> (relative_time that) const
Compare with another interval.
bool operator<= (relative_time that) const
Compare with another interval.
bool operator>= (relative_time that) const
Compare with another interval.
bool operator== (relative_time that) const
bool operator!= (relative_time that) const
unsigned nanoseconds () const
Number of nanoseconds.
unsigned seconds () const
Number of seconds.
unsigned minutes () const
Number of minutes.
unsigned hours () const
Number of hours.
unsigned days () const
Number of days.
bool isnegative () const
Is this a negative interval?
timetype total () const
Total number of seconds, as encoded.
Static Public Member Functions
static void set_digits (unsigned num)
Set number of digits to use when printing (for fractions of seconds).
static unsigned get_digits ()
Get the number of digits that is used when printing.
Friends
std::ostream & operator<< (std::ostream &s, relative_time t)
Write the interval to a std::ostream.
Detailed Description
Time interval.
Constructor & Destructor Documentation
shevek::relative_time::relative_time (timetypeseconds, unsignednanoseconds)
Fast constructor. This directly fills the members and is therefore slightly faster than the other constructors. However, the others aren't
really slow either.
Member Function Documentation
bool shevek::relative_time::operator!= (relative_timethat) const Compare two intervals. Note that this is rarely a useful operation, because
minor errors may be introduced by computations.
bool shevek::relative_time::operator== (relative_timethat) const Compare two intervals. Note that this is rarely a useful operation, because
minor errors may be introduced by computations.
