NAME

termcap − terminal capability database

USAGE

/etc/termcap

DESCRIPTION

Termcap is a database describing terminals, used, e.g., by vi(1) and curses(3X).  This file includes definitions of the capabilities of various terminals, and details about how these terminals handle various operations.  Padding requirements and initialization sequences are included in termcap. 

Entries in termcap consist of a number of colon-separated fields.  The first entry for each terminal gives the names known for the terminal, separated by | characters.  The first name is always 2 characters long and is used by older version 6 systems which store the terminal type in a 16 bit word in a system-wide database.  The second name given is the most common abbreviation for the terminal, and the last name given should be a long name fully identifying the terminal.  The second name should contain no blanks; the last name may well contain blanks for readability.
