It is retained only for capability with old programs; new programs should use the ter- minfo(5) database and associated libraries. /etc/termcap is an ASCII file (the database master) that lists the ca- pabilities of many different types of terminals. Programs can read termcap to find the particular escape codes needed to control the vis- ual attributes of the terminal actually in use. (Other aspects of the terminal are handled by stty(1).) The termcap database is indexed on the TERM environment variable. Termcap entries must be defined on a single logical line, with '\' used to suppress the newline. Fields are separated by ':'. The first field of each entry starts at the left-hand margin, and contains a list of names for the terminal, separated by '|'. The first subfield may (in BSD termcap entries from versions 4.3 and earlier) contain a short name consisting of two characters. This short name may consist of capital or small letters. In 4.4BSD, termcap en- tries this field is omitted. The second subfield (first, in the newer 4.4BSD format) contains the name used by the environment variable TERM. It should be spelled in lowercase letters. Selectable hardware capabilities should be marked by appending a hyphen and a suffix to this name. See below for an ex- ample. Usual suffixes are w (more than 80 characters wide), am (auto- matic margins), nam (no automatic margins), and rv (reverse video dis- play). The third subfield contains a long and descriptive name for this termcap entry. Subsequent fields contain the terminal capabilities; any continued ca- pability lines must be indented one tab from the left margin. Although there is no defined order, it is suggested to write first boolean, then numeric, and then string capabilities, each sorted alpha- betically without looking at lower or upper spelling. Capabilities of similar functions can be written in one line.

A ^x means Control-x. Control-A equals 1 decimal. \x means a special code. x can be one of the following characters: E Escape (27) n Linefeed (10) r Carriage return (13) t Tabulation (9) b Backspace (8) f Form feed (12) 0 Null character. A \xxx specifies the octal character xxx. i Increments parameters by one. r Single parameter capability + Add value of next character to this parameter and do binary out- put 2 Do ASCII output of this parameter with a field with of 2 d Do ASCII output of this parameter with a field with of 3 % Print a '%' If you use binary output, then you should avoid the null character ('\0') because it terminates the string. You should reset tabulator expansion if a tabulator can be the binary output of a parameter. Warning: The above metacharacters for parameters may be wrong: they docu- ment Minix termcap which may not be compatible with Linux term- cap. The block graphic characters can be specified by three string capabili- ties: as start the alternative charset ae end the alternative charset ac pairs of characters. The first character is the name of the block graphic symbol and the second characters is its defini- tion. The following names are available: + right arrow (>) , left arrow (<) . down arrow (v) 0 full square (#) I lantern (#) - upper arrow (^) ' rhombus (+) a chess board (:) f degree (') g plus-minus (#) h square (#) j right bottom corner (+) k right upper corner (+) l left upper corner (+) m left bottom corner (+) n cross (+) o upper horizontal line (-) q middle horizontal line (-) s bottom horizontal line (_) t left tee (+) u right tee (+) v bottom tee (+) w normal tee (+) x vertical line (|) ~ paragraph (???) The values in parentheses are suggested defaults which are used by the curses library, if the capabilities are missing.
