This manual describes version &appversion; of &app;.

## Feedback

To report a bug or make a suggestion regarding the &app; application or this manual, follow the directions in the GNOME Feedback Page.

## Introduction

&app; is a terminal emulation application that you can use to perform the following tasks:

Access a UNIX shell in the GNOME environment

  A shell is a program that interprets and executes the commands that you type at a command line prompt. When you start &app;, the application starts the default shell that is specified in your system account. You can switch to a different shell at any time.

Run any application that is designed to run on VT102, VT220, and xterm terminals

  &app; emulates the xterm application developed by the X Consortium. In turn, the xterm application emulates the DEC VT102 terminal and also supports the DEC VT220 escape sequences. An escape sequence is a series of characters that starts with the Esc character. &app; accepts all of the escape sequences that the VT102 and VT220 terminals use for functions such as to position the cursor and to clear the screen.

## Getting Started

The following sections describe how to start &app;.

### Starting &app;

You can start &app; in the following ways:

Applications menu

  Choose Accessories Terminal.

Command line

  Execute the following command: `gnome-terminal`

  You can use command line options to modify the way in which you run &app;. To view the command line options, execute the following command: `gnome-terminal --help`

### When You First Start &app;

When you start &app; for the first time, the application opens a terminal window with a group of default settings. The group of default settings is called the Default profile. The profile name appears in the titlebar of the &app; window.

#### Example of a Default &app; Window

&app; default window
&app; default window

The terminal window displays a command prompt where you can type UNIX commands. The command prompt can be a %, #, >, $, or any other special character. The cursor is positioned at the command prompt. When you type a UNIX command and press Return, the computer executes the command. By default, &app; uses the default shell specified for the user who starts the application.

&app; also sets the following environment variables:

`TERM`

  Set to `xterm` by default.

`COLORTERM`

  Set to `gnome-terminal` by default.

`WINDOWID`

  Set to the X11 window identifier by default.

### Terminal Profiles

You can create a new profile, and apply the new profile to the terminal to modify characteristics such as font, color and effects, scroll behavior, window title, and compatibility. You can also specify a command that runs automatically when you start &app; in the profile.

You define each terminal profile in the Edit Profiles dialog, which you access from the Edit menu. You can define as many different profiles as you require. When you start a terminal, you can choose the profile that you want to use for the terminal. Alternatively, you can change the terminal profile while you use the terminal. To specify an initial profile for a terminal when you start the application from a command line, use the following command:

`gnome-terminal --window-with-profile=profilename`

The name of the current profile appears in the titlebar of the &app;, unless you specify a different titlebar name in the Editing Profile dialog.

See for information about how to define and use a new terminal profile.

### Working With Multiple Terminals

&app; provides a tab feature that enables you to open several terminals in a single window. Each terminal opens in a separate tab. Click on the appropriate tab to display the terminal in the window. Each tabbed terminal in a window is a separate subprocess, so you can use each terminal for different tasks. You can apply a different profile to each tabbed terminal in the window.

The titlebar of the terminal window shows either the name of the current profile, or the name specified by the current profile. shows a &app; window with four tabs. In this case, each of the four tabs has a different profile. The name of the profile in the active tab, Profile 1, appears in the titlebar.

#### Example of a Terminal Window With Tabs

&app; default window
&app; default window

See for information about how to open a new tabbed terminal.
