Ubuntu :: Formatted Output To Terminal - Fields Need Updating
Jan 25, 2010
I'm writing a couple of programs in C and need to do something to formatting the output. I'm after producing something like a old mainframe screen or early micro where you could PRINT (x,y) to put something on the terminal where you want it. Learning GTK or such is not an option due to time constraints, and some fields need updating frequently during processing, so letting the terminal scroll is going to drive the operator up the wall pretty quickly.

I am faced with the following problem; I need to update all fields of type datetime without ... with the following sort data:01-01-2010 12:10:30.256 - this is just an example.these fields are restricted with a unique constrained. My question is how can I generate the above sort data, especially the last three numbers with leading point. After that how can I update a table with existing data with this newly generated data so that the fields really do carry unique data.As you probably can read out of my question, I read through the help in pgAdmin and came as far as generating date, maybe datetime but not the .123 number. And a little insert script I found in the help, that I modified as UPDATE resulted in updating only the last generated data in all required fields.

It's a pretty weird issue I'm having, when I need to provide access for a command in terminal IE: something using sudo, it just doesn't accept text. I thought it might be my keyboard at first (g15) but I tried copying and pasting the password into there and it just wouldn't do anything except for remain blank

hello
I tried to find a good subject but it was the best of mine, anyway I'll explain it here.
some time I do some thing like installing a new application in Linux terminal of my office PC but it take a long time and I have to go home during its installation or configuration process that it is not good to cancel it.My current solution is abandoning the process until next day. I wanted to know is there any way to redirect an input and out put of a terminal to another one, if it works I can continue my abandoned process by ssh to my Linux office PC and redirect that terminal to my new remote sshed terminal from my home.
Thank a lot for any help.

if you do the command conky in terminal, it starts conky ofcourse, but it also shows output to that terminal so you can't do any other commands to that terminal, Is their an option like you can do with the '&' sign in other cases? If you do the '&' sign with conky it still gives output, also the conky -d command gives output...

I want to update my gnome to the latest version (2.30) because I have 2.28 so I go to terminal and enter the command "apt-get" or try "zypper dup" which both ask for root so I just add "sudo" before the commands and when it ask for the password it doesnt let me write it.

This must've been done before: I want to keep a log file open in terminal so I can monitor updates to it as they occur. My searches are coming up with everything but this situation... I must be missing some terminology or something key, because people do this all the time inside of other programs (NetBeans, or rails server, for example).

I would like to capture all output spewed to a terminal session including processes that are terminated that were invoked from a script running in a terminal window. this is beyond capturing just stderr and stdout . for example
{
./script
} 2> stderr.cap 1>stdout.cap
if script is terminated (including because of memory violations) I get spewed output to the terminal I would like to capture that spewing to a file automatically or to a bit bucket /dev/null Is there another filehandle which can be redirected to do this? If so how or is there another way???

In synaptic package manager when I expand "Details" tab (at the time when some software is installed or removed), I can see a terminal. I want to capture the output of terminal into a file. I tried to highlight and right click. But there is no context menu(copy, cut)

I'd like to write a script that invokes a gnome-terminal session which slowly reads out text like the phosphor screensaver (could be anything, a log file, ascii art, song lyrics, whatev) and then closes. I can invoke a terminal using [gnome-terminal -e 'cat /var/log/dmesg'] but the output flies pass by too quickly.any way to slow it down? I know it seems like an odd request but if anyone has a suggestion I'd love to hear it.

I sometimes stick my neck out and provide somewhat detailed, and often risky, "Mr-fix-it" remedies for boot problems. Now, I know it's possible to amend each command with "whatever_command > whatever.txt" in which case it'll place the command output in a file in /home.
But if you're directing someone to run a lot of commands as I did here is it possible to save the output of all commands to a .txt file without amending each command?
Or is it already saved somewhere that I'm not yet aware of? I wouldn't be surprised if the latter were true, I just haven't yet found it

I have searched a lot for solutions of this problem, but there seems to be no solution that works for me. It was time to update my installation... AS I have NEVER updated it. So I ran the update manager and launched updates. Many packages completed, but linux-image-2.6.32-25-generic (2.6.32-25.44) gave me a lot of errors. I don't ave the terminal output from the update manager, but I have info from apt-get install -f. I am using root account.
Code:
root@ubuntu:~# apt-get upgrade vlc

I've done some searching on googlubuntu for and answer to this but haven't found anything.
As a Linux newbie I was wondering if there are certain types of output from the terminal I should beware of posting for everyone to see? Also are there any codes; that, if I were to be asked to run and report the output on, should raise a red flag?

There is text based game in the Ubuntu repos called gomoku (just 5 in a row) it comes with the package bsdgames. The manual page [URL] lists an option (-b) to run it in the background. I want to try that and if I know how it works create a simple graphical front-end. When I start the program with:
Code:
gomoku -b
it starts and remains active, the terminal does not return to prompt which is OK as the command is not finished. The manual says the program reads from stdin, and this might sound stupid but how to get anything there?
I've tried to pipe an echo command to gomoku which works but ends the program after is receives input.
Code:
echo "black" | gomoku -b
just finishes. After that when you type another command like:
Code:
echo "justsometext" | gomoku -b
gomoku tells it expects either black or white as input. So it forgot the previous "black" because it is a new instance.
How do I pass text to an already running gomoku?

When I type (in new 10.10) soem cmdline comands like "ls -l" then some of the directories have a different fore-and background color (e.g. black on green) while the remaining other directoreis are blue on white.
Where can I find out the meaning of the diferent colors and how can I change them?
If I go to menu
Terminal->Edit->Profile Preferences->Color
then I can set only the full overall background and foreground color. But here only certain parts have a different color. the main color (black on white) is suitable. I do not use system theme.

I have a server client prog in which server is my 'agent' and client is 'manager'. Following is the code for both agent and manager. I want my agent to send what manager is requesting. But it is not working the way I want. The parameters which manager is requesting, agent has to send to manager but in this program result for those parameters is shown on agent's own terminal window. Where as I want them on manager's window. Secondly, there result is not correct, means it is giving ' 0 K ram and 0 no of process....
Code:
//code for MANAGER
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>
#include <stdio.h>
#include <unistd.h>
#include <errno.h> .....

I am trying to display a text using crontab. My settings :
*/2 * * * * /bin/echo "hello"
This setting sends a mail to the user, instead of displaying on the screen. Now tried changing the setting to:
*/2 * * * * /bin/echo "hello" > /dev/tty1
Now I can see the text on the screen, but this setting comes with a catch. What would happen if the user changes the terminal. for instance if he gets into tty2, he wont have write access on tty1. So the user gets a mail saying "permission denied". Is there any way that I can force the user to use a particular terminal or can a cron job be set in a way such that the user would get the text irrespective of the terminal he logs in.

I'm installing and configuring my first server using RackSpace CloudServers running Ubuntu Karmic Koala (9.10) and I'm now installing iRedMail. The installation runs successfully until I recieve this error:
Code:
The following packages have unmet dependencies: mysql-server-5.0: Depends: mysql-server-core-5.0 (>= 5.1.30really5.0.83-0ubuntu3) but it is not going to be installed
E: Broken packages < ERROR > Installation failed, please check the terminal output. I understand this is telling me there is some software that iRedMail (or something iRedMail is dependant upon) that needs installed. Is this correct? And if so, what is i needing installed and how do I do that (aptitude install example-package?)?

I'm new to Fedora and the Red Hat way of doing things, having been a Ubuntu/Mint user for the last 5-6 years. I've been using Fedora for my daily computer now for the last 3-4 months - a change that has definitely been for the better! However, earlier this morning I went to install a .rpm, and yum output via terminal the following error:
Code:
[leeky@darkstar ~]$ sudo yum install opera
[sudo] password for leeky:
Loaded plugins: fastestmirror, langpacks, presto, refresh-packagekit
Adding en_US to language list
Loading mirror speeds from cached hostfile
* fedora: mirror.netrino.co.uk
* rpmfusion-free: mirror01.th.ifl.net
* rpmfusion-free-updates: mirror01.th.ifl.net
* rpmfusion-nonfree: mirror01.th.ifl.net
* rpmfusion-nonfree-updates: mirror01.th.ifl.net
* updates: mirror.netrino.co.uk
Error: database disk image is malformed
[leeky@darkstar ~]$
This is the first time I have received this error. I've now tried the following methods of resolving this problem with no luck:
1. Code:
yum clean all
2. Code:
yum clean metadata
yum clean dbcache
yum makecache
3. Physically removing the /var/libs/yum folder, and creating a new "yum" folder, and then step two above to rebuild it. Either way the problem then still returns in terminal.

I want local programmatic access to ssh output in Mac Terminal. First, I tried redirecting the output of each command to a file. The file was perfect, but of course it was on the remote server, and an sftp for each command output seemed a little.. Next, I tried to Applescript Terminal, but it only gives access to the currently visible text in a tab (i.e. if half the output has already scrolled out of sight, it doesn't get returned - useless).
Last, I tried piping ssh to tee (e.g. ssh user@host | tee output.txt). This almost worked. I have the output in a local file, but there are a lot of unwanted characters mixed in. For example, every time I hit backspace, there's a ^H in the file. There's also text like "[0m[K" which is harder to get rid of.
