To use the value of an option, prefix the name of the option with
'&', e.g.,
:echo &ft
The option value &ft has to be expanded and Vim needs to be told to
expand it rather than pass it to the shell command literally. That
can be be done with the :execute command, which expands its
arguments before executing the resulting expression, e.g.,
:execute ".!tplt" &ft
Note that the range has to be part of the expression that :execute
executes; the range can't come before "execute".
Note also that :execute inserts spaces between its arguments.
See
:help expr-option
:help :execute
