I am trying to write a shell script that starts a program, reads from its stdout and can write to its stdin.
I'm having trouble to get it to work, I tried using named pipes, and using exec and file descriptors.
Just couldn't get it to work, so I thought I'll post it here to see if someone is willing to help me.
The program is called primes, and it first asks for my name

Hi Everybody,
I'm trying to create a script that will launch firefox from a bash shell in ubuntu and perform certain tasks.
Why does it have to be a script? Because this firefox must eventually run in a server with xvfb (no gnome, no kde), so I will not have access to it through the GUI.

Hi,
I wanted to write a schell program that fetches the values from a file and prints the output as its onerall multiplication.
for example I have a file named abc. it has values 2, 3, 4
now my program should give me 2*3*4 ie 24.
note:this file abc can have any numbers.
so experts,... (9 Replies)

matho-primes
MATHO-PRIMES(1) Mathomatic Utilities MATHO-PRIMES(1)NAME
matho-primes - generate consecutive prime numbers
SYNOPSIS
matho-primes [start [stop]] ["twin"] ["pal" [base]]
matho-primes [-htu] [-c count] [-m number] [-p base] [start [stop]]
DESCRIPTION
This command-line utility is optionally part of the mathomatic(1) package. It quickly computes any number of consecutive prime numbers
using a windowing, memory efficient sieve of Eratosthenes algorithm, dumping them to standard output. They are displayed one prime per
line in ascending order, unless the "twin" option is specified, which displays only twin primes, two primes per line.
Generates up to 18 decimal digit primes, or whatever is the number of digits of precision for a floating point long double in the C com-
piler used to compile this utility. Note that this utility might be compiled to use only double precision floating point, if long double
precision is not fully supported by the C compiler or hardware, allowing at most 15 decimal digit primes in that case.
Ways to verify that this utility is working are to pipe the output into the Unix "factor" utility, or compare the output with the BSD Games
"primes" utility.
All numbers displayed by this utility are decimal (base 10) prime numbers. A prime number is an integer that cannot be factored.
A range may be specified on the command line, otherwise the starting number and the number of primes to output is prompted for. The range
is start to stop inclusive, and stop must be greater than or equal to start.
If the -c option is specified, the number of lines of primes displayed is limited to the decimal count that follows this option.
If the -t or "twin" option is specified on the command line, only twin primes will be displayed. Twin primes are two primes that differ in
value by 2. Each twin pair is displayed together on the same line separated by a space character.
If the -p or "pal" option is specified on the command line, only palindromic primes are displayed. Palindromes are symmetrical, they read
exactly the same forward and backward. The palindromic number base may be specified, the default is base 10. The base can be any integer
greater than 1. Primes are always displayed in decimal (base 10).
The version number and short help on the allowed command-line parameters and usage information are displayed when given the -h option.
With the -u option, all output (standard output and standard error output) is set to be unbuffered, making all output happen immediately,
instead of when the output buffer is full or when the program terminates or waits for input.
The -m option changes the memory size of the prime number sieve window. It is followed by a decimal, floating point number which is a mul-
tiplier of the default window size. It is possible that changing the memory size may speed up the total run time; otherwise there is no
reason to use this option.
