It sunds more like a quoting imbalance, where the te got hidden.
I usually go for the quieter:
The there is the ever favorite no tee, just log to file, and to watch:
Sometimes long commands, even sub-shells and scripts, will buffer, stopping mid-line, but usually at each command end the log catches up.
Programmers can help by either calling flush() periodically to clean FILE* buffers, or initially calling setvbuf() to configure line buffering. I used to use setvbuf for a huge buffer, and flush to write whole log blocks in one piece, because I had many servers writing the same logs.

ng_tee
NG_TEE(4) BSD Kernel Interfaces Manual NG_TEE(4)NAME
ng_tee -- netgraph ``tee'' node type
SYNOPSIS
#include <sys/types.h>
#include <netgraph/ng_tee.h>
DESCRIPTION
The tee node type has a purpose similar to the tee(1) command. Tee nodes are useful for debugging or ``snooping'' on a connection between
two netgraph nodes. Tee nodes have four hooks, right, left, right2left, and left2right. All data received on right is sent unmodified to
both hooks left and right2left. Similarly, all data received on left is sent unmodified to both right and left2right.
Packets may also be received on right2left and left2right; if so, they are forwarded unchanged out hooks right and left, respectively.
HOOKS
This node type supports the following hooks:
right The connection to the node on the right.
left The connection to the node on the left.
right2left Tap for right to left traffic.
left2right Tap for left to right traffic.
CONTROL MESSAGES
This node type supports the generic control messages, plus the following.
NGM_TEE_GET_STATS
Get statistics, returned as a struct ng_tee_stats.
NGM_TEE_CLR_STATS
Clear statistics.
SHUTDOWN
This node shuts down upon receipt of an NGM_SHUTDOWN control message, or when all hooks have been disconnected. If both right and left hooks
are present, node removes itself from the chain gently, connecting right and left together.
SEE ALSO tee(1), netgraph(4), ngctl(8)HISTORY
The ng_tee node type was implemented in FreeBSD 4.0.
