|

|
|---|
| 13 | <para>The libraries that make up the Ncurses library are used to display text
|
|---|
| 14 | (often in a fancy way) on the screen. An example where ncurses is used
|
|---|
| 15 | is in the kernel's <quote>make menuconfig</quote> process. The libraries
|
|---|
| 16 | contain routines to create panels, menu's, form and general text display
|
|---|
| 17 | routines.</para></sect3>

|
|---|
| 20 | <para>The clear program clears the screen if this is possible. It looks in
|
|---|
| 21 | the environment for the terminal type and then in the terminfo database
|
|---|
| 22 | to figure out how to clear the screen.</para></sect3>

|
|---|
| 25 | <para>The infocmp program can be used to compare a binary terminfo entry with
|
|---|
| 26 | other terminfo entries, rewrite a terminfo description to
|
|---|
| 27 | take advantage of the use= terminfo field, or print out a
|
|---|
| 28 | terminfo description from the binary file (term) in a variety of
|
|---|
| 29 | formats (the opposite of what tic does).</para></sect3>

|

| 31 | <sect3><title>Tic</title>
|
|---|
| 32 | <para>Tic is the terminfo entry-description compiler. The program translates a
|
|---|
| 33 | terminfo file from source format into the binary format for use with the
|
|---|
| 34 | ncurses library routines. Terminfo files contain information about the
|
|---|
| 35 | capabilities of a terminal.</para></sect3>

|

| 38 | <para>The toe program lists all available terminal types by primary name with

| 39 | descriptions.</para></sect3>

| 41 | <sect3><title>tput</title>
|
|---|
| 42 | <para>The tput program uses the terminfo database to make the values of
|
|---|
| 43 | terminal-dependent capabilities and information available to the shell,
|
|---|
| 44 | to initialize or reset the terminal, or return the long name of the
|
|---|
| 45 | requested terminal type.</para></sect3>

|

| 47 | <sect3><title>tset</title>
|
|---|
| 48 | <para>The Tset program initializes terminals so they can be used, but it's not
|
|---|
| 49 | widely used anymore. It's provided for 4.4BSD compatibility.</para></sect3>
