+.SH NAME
+tput
+\(em change terminal characteristics
+.SH SYNOPSIS
+.LP
+.nf
+tput \fB[\fR-T \fItype\fB] \fIoperand\fR...
+.fi
+.SH DESCRIPTION
+The
+.IR tput
+utility shall display terminal-dependent information. The manner in
+which this information is retrieved is unspecified. The information
+displayed shall clear the terminal screen, initialize the user's
+terminal, or reset the user's terminal, depending on the operand
+given. The exact consequences of displaying this information are
+unspecified.
+.SH OPTIONS
+The
+.IR tput
+utility shall conform to the Base Definitions volume of POSIX.1\(hy2017,
+.IR "Section 12.2" ", " "Utility Syntax Guidelines".
+.P
+The following option shall be supported:
+.IP "\fB\-T\ \fItype\fR" 10
+Indicate the type of terminal. If this option is not supplied and the
+.IR TERM
+variable is unset or null, an unspecified default terminal type shall
+be used. The setting of
+.IR type
+shall take precedence over the value in
+.IR TERM .
+.SH OPERANDS
+The following strings shall be supported as operands by the
+implementation in the POSIX locale:
+.IP "\fBclear\fR" 10
+Display the clear-screen sequence.
+.IP "\fBinit\fR" 10
+Display the sequence that initializes the user's terminal in an
+implementation-defined manner.
+.IP "\fBreset\fR" 10
+Display the sequence that resets the user's terminal in an
+implementation-defined manner.
+.P
+If a terminal does not support any of the operations described by these
+operands, this shall not be considered an error condition.
+.SH STDIN
+Not used.
+.SH "INPUT FILES"
+None.
+.SH "ENVIRONMENT VARIABLES"
+The following environment variables shall affect the execution of
+.IR tput :
+.IP "\fILANG\fP" 10
+Provide a default value for the internationalization variables that are
+unset or null. (See the Base Definitions volume of POSIX.1\(hy2017,
+.IR "Section 8.2" ", " "Internationalization Variables"
+for the precedence of internationalization variables used to determine
+the values of locale categories.)
+.IP "\fILC_ALL\fP" 10
+If set to a non-empty string value, override the values of all the
+other internationalization variables.
+.IP "\fILC_CTYPE\fP" 10
+Determine the locale for the interpretation of sequences of bytes of
+text data as characters (for example, single-byte as opposed to
+multi-byte characters in arguments).
+.IP "\fILC_MESSAGES\fP" 10
+.br
+Determine the locale that should be used to affect the format and
+contents of diagnostic messages written to standard error.
+.IP "\fINLSPATH\fP" 10
+Determine the location of message catalogs for the processing of
+.IR LC_MESSAGES .
+.IP "\fITERM\fP" 10
+Determine the terminal type. If this variable is unset or null, and if
+the
+.BR \-T
+option is not specified, an unspecified default terminal type shall be
+used.
+.SH "ASYNCHRONOUS EVENTS"
+Default.
+.SH STDOUT
+If standard output is a terminal device, it may be used for writing the
+appropriate sequence to clear the screen or reset or initialize the
+terminal. If standard output is not a terminal device, undefined
+results occur.
+.SH STDERR
+The standard error shall be used only for diagnostic messages.
+.SH "OUTPUT FILES"
+None.
+.SH "EXTENDED DESCRIPTION"
+None.
+.SH "EXIT STATUS"
+The following exit values shall be returned:
+.IP "\00" 6
+The requested string was written successfully.
+.IP "\01" 6
+Unspecified.
+.IP "\02" 6
+Usage error.
+.IP "\03" 6
+No information is available about the specified terminal type.
+.IP "\04" 6
+The specified operand is invalid.
+.IP >4 6
+An error occurred.
+.SH "CONSEQUENCES OF ERRORS"
+If one of the operands is not available for the terminal,
+.IR tput
+continues processing the remaining operands.
+.LP
+.IR "The following sections are informative."
+.SH "APPLICATION USAGE"
+The difference between resetting and initializing a terminal is left
+unspecified, as they vary greatly based on hardware types. In general,
+resetting is a more severe action.
+.P
+Some terminals use control characters to perform the stated functions,
+and on such terminals it might make sense to use
+.IR tput
+to store the initialization strings in a file or environment variable
+for later use. However, because other terminals might rely on system
+calls to do this work, the standard output cannot be used in a portable
+manner, such as the following non-portable constructs:
+.sp
+.RS 4
+.nf
+
+ClearVar=`tput clear`
+tput reset | mailx -s "Wake Up" ddg
+.fi
+.P
+.RE
+.SH EXAMPLES
+.IP " 1." 4
+Initialize the terminal according to the type of terminal in the
+environmental variable
+.IR TERM .
+This command can be included in a
+.BR .profile
+file.
+.RS 4 
+.sp
+.RS 4
+.nf
+
+tput init
+.fi
+.P
+.RE
+.RE
+.IP " 2." 4
+Reset a 450 terminal.
+.RS 4 
+.sp
+.RS 4
+.nf
+
+tput -T 450 reset
+.fi
+.P
+.RE
+.RE
+.SH RATIONALE
+The list of operands was reduced to a minimum for the following
+reasons:
+.IP " *" 4
+The only features chosen were those that were likely to be used by
+human users interacting with a terminal.
+.IP " *" 4
+Specifying the full
+.IR terminfo
+set was not considered desirable, but the standard developers did not
+want to select among operands.
+.IP " *" 4
+This volume of POSIX.1\(hy2017 does not attempt to provide applications with sophisticated
+terminal handling capabilities, as that falls outside of its assigned
+scope and intersects with the responsibilities of other standards
+bodies.
+.P
+The difference between resetting and initializing a terminal is left
+unspecified as this varies greatly based on hardware types. In
+general, resetting is a more severe action.
+.P
+The exit status of 1 is historically reserved for finding out if a
+Boolean operand is not set. Although the operands were reduced to a
+minimum, the exit status of 1 should still be reserved for the Boolean
+operands, for those sites that wish to support them.
+.SH "FUTURE DIRECTIONS"
+None.
