seconds, the default

is 15 seconds.

can be given to limit the total running time of the
.I tra,

normally copies out all the text currently in the file
before beginning to watch for new text.

.I Tra
is particularly useful for alternately watching the output
file being written by a long shell script or a long-running
program and doing real work.
