I have used an script in past that enabled me to connect me to multiple unix machines, much like using a tab. Its just that I forgot the name of the script. Anyone know about it?
I suspect you're referring to GNU screen, which is a terminal multiplexer that allows you to have multiple virtual terminal windows in a single normal terminal window (ala PuTTY). I'd suggest tmux as a better alternative, but they're essentially the same. There are other solutions that will allow you to do tabs in the terminal client, but that depends on your OS (I'm assuming you're on Windows), and you'd have to initiate each connection individually. screen/tmux is the way to go most of the time.

My question is very simple.
How does OSX understands that this special process needs to make output to special terminal? Can we change it?
For example, is it possible to run process via ssh connection (without GUI) and make some system call, and this process will start using OSx GUI
I don't really understand your question, but I suspect you maybe have a look at the "expect" tool, which allows you to start some connection and then let the user continue after you have established the connection. Try:
man expect
in a terminal window.
In the past, I have used MATLAB sparingly from Linux machines at work, and I far and away preferred using the '-nodesktop' option. On all Unix-like machines I've worked on this option allows me to control STDIN and STOUT with relative ease, but on Windows(using Cygwin) this option spawns a new window and control is returned to the calling shell!
Basically, I would like to know if there is any way that I can force MATLAB to behave as it would on a Unix-like machine?
Thanks!
Short answer: You can not.
A longer answer can be found on their website.
-nodesktop behaves differently depending if you are on Windows vs
Linux or Mac. On Windows we provide a boring Command-Window only
interface that lacks the “bells and whistles” of the regular Command
Window or the full Desktop.
So you can use -nodesktop, but it pops up that annoying command line only window.
I am new to cygwin, since I usually use Linux. I had a quick question regarding it. From the xterm window of cywin, how do I create multiple terminal tabs, so that I can have multiple ssh (with X11 forwarding) sessions from the same window?
I tried googling this, but could not find any useful link for this problem.... I am sure there is some way to do this, just can't figure it out.
Thanks a lot for your help!
If you're already open to starting up X11, check out mrxvt. It does multiple tabs, and last I checked, it built smoothly under Cygwin.
There's also Terminator, which is a java terminal emulator... ISTR it doesn't require X11.
Hey there, I'm building a remote shell server that interfaces between a text-only client and a virtual shell.
It works perfectly when using regular shell commands, but the first thing that people try after that is vim, which promptly drives my server crazy and can't even be closed remotely.
Is there any way to detect ncurses based programs and prevent them from running in my special shell?
(the server is ruby, but any system command will do)
You can declare the capabilities your shell has, by setting the TERM environment variable to the correct value. For instance, if your shell has the same capabilities as the vt100 terminal, export TERM to the correct value, and programs like vim will respect that.
To run vim in vt100-mode, try:
TERM=vt100 vim
You could also try:
export TERM=dumb
The trick is to find a terminal that corresponds to the capabilities of what you are creating. There is a lot to choose from. On my system (Arch Linux) this gives me a long list of choices:
find /usr/share/terminfo
You might be able to find a terminal specification that corresponds to what your program can handle.
Alternatively, you may want to consider implementing terminal emulation for ansi or vt100:

Best of luck!
How can I have another Terminal open when I am at my server by ssh?
I do not want to type my password twice to get another terminal for my server.
Perhaps, Bash has buffers similarly as Vim.
Check out GNU screen. It's kind of arcane and awkward to use, but does what you're looking for, and it's probably also installed on your server.
You can also forward X11 and run multiple xterm instances, but that's a pain.
Your best bet, though, is your proverbial "type my password every time" solution: you should set up SSH keys so you don't need to type your password every time and then just use multiple connections in Terminal tabs.
You can use something like GNU Screen.
The Bash shell has a feature called Job Control that allows you to run and manage multiple processes. You can read about it here: http://commandlinemac.blogspot.com/2008/12/bash-job-control-fg-bg-jobs-and-ctrl-z.html
GNU Screen
BTW. If you don't like typing passwords, try PK auth.
How it's done with PuTTy.
It's possible to use screen to open other terminals without needing to authenticate again.
Screen can also detach so that you can leave terminal open after logging out and re-attach them later. I use this on my home server for keeping rtorrent open.
