Thank you, but I don't have much time for learning how the screen works, so I would be glad to find some other way. Here is a test srcipt that I came up with so far:
I would like, for example, the child process to print the time in the third line of the terminal, and the parent - just write "parent" multiple times in 4th line, in the same place, by overwriting the previous one. But both processes seem to be writing in the same line - can it be fixed somehow?
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)
In the below bash when the perl is it possible to hide the commands from running on screen and display a process countdown?

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)

iv_timer_unregister
iv_timer(3) ivykis programmer's manual iv_timer(3)NAME
iv_timer_register, iv_timer_unregister, iv_timer_registered - deal with ivykis timers
SYNOPSIS
#include <iv.h>
struct iv_timer {
struct timespec expires;
void *cookie;
void (*handler)(void *);
};
void IV_TIMER_INIT(struct iv_timer *timer);
void iv_timer_register(struct iv_timer *timer);
void iv_timer_unregister(struct iv_timer *timer);
int iv_timer_registered(struct iv_timer *timer);
DESCRIPTION
The functions iv_timer_register and iv_timer_unregister register, respectively unregister, a timer with the current thread's ivykis event
loop. iv_timer_registered on a timer returns true if that timer is currently registered with ivykis.
When a timer that is registered becomes 'ready', due to the current system clock value becoming greater than or equal to the timer's
->expires member field, the callback function specified by ->handler is called in the thread that the timer was registered in, with
->cookie as its first and sole argument. When this happens, the timer is transparently unregistered.
The application is allowed to change the ->cookie and ->handler members at any time. The application is not allowed to change the
->expires member while the timer is registered.
A given struct iv_timer can only be registered in one thread at a time, and a timer can only be unregistered in the thread that it was reg-
istered from.
There is no limit on the number of timers registered at once.
