Set terminal-dependent capabilities, color, position.
Syntax tput [-Ttype] capname [parms ... ] tput [-Ttype] init tput [-Ttype] reset tput [-Ttype] longname tput -S << tput -V Key -Ttype Indicates the type of terminal. Normally this option is unnecessary because the default is taken from the environment variable TERM. f -T is specified, then the shell variables LINES and COLUMNS will be ignored,and the operating system will not be queried for the actual screen size. capname Indicates the capability from the terminfo database. When termcap support is compiled in, the termcap name for the capability is also accepted. Typical capabilities include: tput setab color Set ANSI Background color tput setaf color Set ANSI Foreground color tput blink Set blink mode tput bold Set bold mode tput dim Set half-bright mode tput smul Set underline mode tput rmul Exit underline mode tput rev Reverse mode tput smso Set standout mode tput rmso Exit standout mode tput sgr0 Reset all attributes tput cols Display the number of columns tput lines Display the number of lines parms If the capability is a string that takes parameters, the arguments parms will be instantiated into the string. -S Allow more than one capability per invocation of tput. The capabilities must be passed to tput from the standard input instead of from the command line (see example). Only one capname is allowed per line. -V Reports the version of ncurses which was used in this program, and exits. init If the terminfo database is present and an entry for the user's terminal exists (see -Ttype, above), output the terminal's initialization strings and turn tabs expansion on or off according to the specification in the entry reset Instead of putting out initialization strings, the terminal's reset strings will be output if present (rs1, rs2, rs3, rf). If the reset strings are not present, but initialization 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)].
If tput is invoked by a link named reset, this has the same effect as tput reset. See tset for comparison, which has similar behavior.
Black = 0
Red = 1
Green = 2
Yellow = 3
Blue = 4
Magenta = 5
Cyan = 6
White = 7
Reset to default color = 9
Colours set with tput may be used as part of a $PS Prompt Statement variable, if you do this, store the output of tput into a variable, which is then used when $PS1 is expanded. Storing the values means we don't have to fork a tput process multiple times every time the prompt is displayed.
The compiled terminal description database is stored at /usr/share/terminfo
tput is part of the ncurses package and is supplied with most Linux distributions.
Echo the clear-screen sequence for the current terminal.
Set the foreground colour to Red.
tput setaf 1
Print the number of columns for the current terminal.
