How do I edit terminfo?
The mechanism for modifying an existing terminfo definition is quite simple.
- Create a source definition for the terminal.
- Edit the source definition for the terminal.
- Compile the source definition for the terminal into a binary entry in the terminfo database.
Where do I put terminfo files?
All of the terminals in the database are in the ncurses-bin package and go into /usr/share/terminfo/. If the compiled terminfo is in more than one location, everything is usually OK until someone installs new terminfo files (from a newer distribution, from the net, by editing the old one, etc.).

- Compile the terminfo entry file into the terminfo database.
What is termcap in Linux?
Termcap (terminal capability) is a software library and database used on Unix-like computers. It enables programs to use display computer terminals in a device-independent manner, which greatly simplifies the process of writing portable text mode applications.
What is terminfo file?
Terminfo is a compiled database describing the capabilities of terminals. Terminals are described in the terminfo source files via entries. Each entry contains information about the capabilities for a particular terminal or set of common terminals.
Why is ncurses called ncurses?
Curses is a pun on the term “cursor optimization”. It is a library of functions that manage an application’s display on character-cell terminals (e.g., VT100). The name “ncurses” was first used as the name of the curses library in Pavel Curtis’s pcurses, dated 1982. the library modules used for the terminfo compiler.
What is xterm-256color?
xterm-256color describes Xterm with support for 256 colors enabled. xterm-color describes an older branch of Xterm that supports eight colors. xterm-color is not recommended, since it describes a variant of Xterm that’s less functional and that you’re not likely to be using.
Where to find terminfo and termcap in Linux?
The source code file (for all terminals) may be /etc/termcap and/or terminfo.src (or another name). See the man pages: terminfo (5) or termcap (5) for the format required to create (or modify) these source files. The file terminfo.src may be in various locations on your computer or it may not be included with your Linux distribution.
Where do I find the terminfo file on my computer?
To see a display of the database for the terminal you’re now using (including a PC monitor) type “infocmp” and you should see the source terminfo “file” for it. To see if your terminal (say vt100) is in the terminfo data base type “locate vt100”.
What is the syntax for the terminfo entry?
Terminfo Capabilities Syntax The terminfo entry consists of several capabilities, i.e., features that the terminal has, or methods for exercising the terminal’s features. After the first field (giving the name (s) of the terminal entry), there should be one or more capability fields.
How is terminfo used in non-curses applications?
It is also used via low-level calls by non-curses applications which may be screen-oriented (such as @CLEAR@ (1)) or non-screen (such as @TABS@ (1)). Terminfo describes terminals by giving a set of capabilities which they have, by specifying how to perform screen operations, and by specifying padding requirements and initialization sequences.
