I am using pipes (specifically piping out) in Perl to put an array from one file into an array in a different file. I can't figure out how to transfer the array. I kow how to open the pipe : open (FILEHANDLE, "| file") or die~
but how do I transfer the array. I think it has something to do with... (1 Reply)
Hi, I am trying to write a program that will pipe any number of programs together like in the linux shell. As an example, the below code tries to execute "cat data | grep int | cut -b 1-10." The problem is that the programs never get executed for some reason. It seems like the first program... (3 Replies)
I've got a file with lots of commands I want to run in it. They're formatted like so:
cp /path/to/file /path/to/new/file
and on and on and on.
Hundreds of them.
Anyways, I'd like to execute them one at a time, then check what time it is, and repeat this process until 7am.

To explain this question I will have to go into a bit of detail. I hope you don't mind.
currently I have a log handler (an already compiled c++ version) and what it does is makes a log file and writes all the unix output (echo, etc) of a script to that log file. To me the log_handler is... (3 Replies)
Hi,
I'm trying to wrap my head around piping in C - I've got a small C program that forks and pipes stuff from the child process to the parent process.
Currently the child process calls a C program that squirts out random numbers which then pipes the result to the parent process.

Hey guys. I'm very new to Unix. I'm pretty fluent in Java and C, but I have never actually used Unix for anything. I am in an Operating Systems course now and I have an assignment to write a piece of code that involves forks and piping. I'm stuck.

tput - query terminfo database
SYNOPSIS
type] capname...
type] capname [parms...]
DESCRIPTION
The command uses the database to make terminal-dependent capabilities and information available to the shell (see terminfo(4)). The com-
mand outputs a string if the attribute (capname) is of type string, or an integer if the attribute is of type integer. If the attribute is
of type boolean, simply sets the exit code for TRUE, for FALSE), and produces no output.
Command-line Arguments
The command recognizes the following command-line arguments:
Indicates the type of terminal.
Normally this flag is unnecessary because the default is taken from the environment variable
capname Indicates the attribute from the database. See terminfo(4). In addition, the following capnames are supported:
Echo the clear-screen sequence for the current terminal.
Echo the initialize sequence for the current terminal.
Echo the sequence that will reset the current terminal.
parms If the capname takes optional numeric parameters, the parms will be placed in the string output by
The capnames are read from stdin and multiple capnames are allowed. Only one capname is allowed per line when reading
from stdin.
EXTERNAL INFLUENCES
Environment Variables
determines the locale to use. This overrides settings of other environment variables.
determines the language to use for messages.
determines the terminal type if the option is not specified.
EXAMPLES
Echo clear-screen sequence for the current terminal.
Print the number of columns for the current terminal.
Print the number of columns for the 70092 terminal.
Set shell variable to stand-out-mode sequence for current terminal.
This might be followed by a prompt:
Set exit code to indicate if current terminal is a hard copy terminal.
Clear the screen, move the cursor to line 10, column 20 and turn on bold.
RETURN VALUE
If capname is of type boolean, then the exit code is set to for true and for false.
If capname is not of type boolean and fails, an error message is printed, and exit code is set to one of the following depending on the
failure:
The capability name is of type integer and does not exist.
Usage error.
Unknown terminal type.
Unknown capability name.
An error occurred.
If the exit code is a is printed if a capability name of type integer is requested for a terminal that has no entry for that capability
name in the database (such as
