TGET(1) 						      General Commands Manual							   TGET(1)

NAME

       tget - get termcap values

SYNOPSIS

       tget [-flag id] [-num id] [-str id] [-goto col line] [[-echo] string]

DESCRIPTION

       Tget  allows  shell  scripts access to the termcap(3) functions.  Flags, numbers and strings can be queried from the termcap database under
       the entry denoted by the environment variable $TERM.

OPTIONS

       -flag id
	      Set the exit status to zero if the flag id is set.  All other options except -echo set the exit status to id being available or not.
	      The last option sets the final exit code.

       -num id
	      Print the value of the numeric variable id.

       -str id
	      Print the value of the string variable id.

       -goto col line
	      Generates instructions to go to the given column and line if the cm capability exists.

       -echo string
	      Prints string.  Any other argument that does not start with a dash is also printed.

EXAMPLE

       Try this: tget -str so 'Reverse Video' -str se

ENVIRONMENT

       TERM	      Terminal type.

       TERMCAP	      Path to the termcap database, by default /etc/termcap:/usr/etc/termcap.

SEE ALSO

       termcap(3).

DIAGNOSTICS

       Tget will fail immediately with a descriptive message if the termcap entry can't be found.
