tput(1) User Commands tput(1) NAME tput - initialize a terminal or query terminfo database SYNOPSIS tput [-T type] capname [parm...] tput -S << DESCRIPTION tput uses the terminfo database to make the values of terminal-depen- dent capabilities and information available to the shell (see sh(1)); to clear, initialize or reset the terminal; or to return the long name of the requested terminal type. tput outputs a string if the capability attribute (capname) is of type string, or an integer if the attribute is of type integer. If the attribute is of type boolean, tput simply sets the exit status (0 for TRUE if the terminal has the capability, 1 for FALSE if it does not), and produces no output. Before using a value returned on standard output, the user should test the exit status ($?, see sh(1)) to be sure it is 0. See the EXIT STATUS section. OPTIONS The following options are supported: -Ttype Indicates the type of terminal. Normally this option is unneces- sary, because the default is taken from the environment variable TERM. If -T is specified, then the shell variables LINES and COL- UMNS and the layer size will not be referenced. -S Allows more than one capability per invocation of tput. The capa- bilities must be passed to tput from the standard input instead of from the command line (see the example in the EXAMPLES sec- tion). Only one capname is allowed per line. The -S option changes the meaning of the 0 and 1 boolean and string exit sta- tuses (see the EXIT STATUS section). OPERANDS The following operands are supported: capname Indicates the capability attribute from the terminfo database. See terminfo(4) for a complete list of capabilities and the cap- name associated with each. The following strings will be supported as operands by the imple- mentation in the "C" locale: clear Display the clear-screen sequence. init If the terminfo database is present and an entry for the user's terminal exists (see -Ttype, above), the following will occur: 1. if present, the terminal's initialization strings will be output (is1, is2, is3, if, iprog), 2. any delays (for instance, newline) specified in the en- try will be set in the tty driver, 3. tabs expansion will be turned on or off according to the specification in the entry, and 4. if tabs are not expanded, standard tabs will be set (ev- ery 8 spaces). If an entry does not contain the informa- tion needed for any of the four above activities, that activity will silently be skipped. reset Instead of putting out initialization strings, the termi- nal's reset strings will be output if present (rs1, rs2, rs3, rf). If the reset strings are not present, but ini- tialization strings are, the initialization strings will be output. Otherwise, reset acts identically to init. longname If the terminfo database is present and an entry for the user's terminal exists (see -Ttype above), then the long name of the terminal will be put out. The long name is the last name in the first line of the terminal's description in the terminfo database (see term(5)). parm If the attribute is a string that takes parameters, the argument parm will be instantiated into the string. An all numeric argu- ment will be passed to the attribute as a number. EXAMPLES Example 1: Using the tput command. This example initializes the terminal according to the type of terminal in the environment variable TERM. This command should be included in everyone's .profile after the environment variable TERM has been ex- ported, as illustrated on the profile(4) manual page. example% tput init The next example resets an AT&T 5620 terminal, overriding the type of terminal in the environment variable TERM: example% tput -T5620 reset The following example sends the sequence to move the cursor to row 0, column 0 (the upper left corner of the screen, usually known as the "home" cursor position). example% tput cup 0 0 The next example echos the clear-screen sequence for the current termi- nal. example% tput clear The next command prints the number of columns for the current terminal. example% tput cols The following command prints the number of columns for the 450 termi- nal. example% tput -T450 cols The next example sets the shell variables bold, to begin stand-out mode sequence, and offbold, to end standout mode sequence, for the current terminal. This might be followed by a prompt: echo "${bold}Please type in your name: ${offbold}\c" example% bold='tput smso' example% offbold='tput rmso' This example sets the exit status to indicate if the current terminal is a hardcopy terminal. example% tput hc This next example sends the sequence to move the cursor to row 23, col- umn 4. example% tput cup 23 4 The next command prints the long name from the terminfo database for the type of terminal specified in the environment variable TERM. example% tput longname This last example shows tput processing several capabilities in one in- vocation. This example clears the screen, moves the cursor to position 10, 10 and turns on bold (extra bright) mode. The list is terminated by an exclamation mark (!) on a line by itself. example% tput -S <<! > clear > cup 10 10 > bold > ! ENVIRONMENT VARIABLES See environ(5) for descriptions of the following environment variables that affect the execution of tput: LC_CTYPE, LC_MESSAGES, and NLSPATH. TERM Determine the terminal type. If this variable is unset or null, and if the -T option is not specified, an unspecified default terminal type will be used. EXIT STATUS The following exit values are returned: 0 o If capname is of type boolean and -S is not specified, in- dicates TRUE. o If capname is of type string and -S is not specified, indi- cates capname is defined for this terminal type. o If capname is of type boolean or string and -S is speci- fied, indicates that all lines were successful. o capname is of type integer. o The requested string was written successfully. 1 o If capname is of type boolean and -S is not specified, in- dicates FALSE. o If capname is of type string and -S is not specified, indi- cates that capname is not defined for this terminal type. 2 Usage error. 3 No information is available about the specified terminal type. 4 The specified operand is invalid. >4 An error occurred. -1 capname is a numeric variable that is not specified in the ter- minfo database; for instance, tput -T450 lines and tput -T2621 xmc.
