Open the file with > and previous contents is overwritten.
BTW if you permanently open it with exec then you can do this
Note that the exec opens the file, either open-truncate with > or open-append with >>, and associates descriptor 2=stderr with it.
Subsequent writes to stderr go to the stream i.e. append.

write
write(1) General Commands Manual write(1)NAME
write - interactively write (talk) to another user
SYNOPSIS DESCRIPTION
The command copies lines from your terminal to that of another user. When first called, it sends the message:
to the receiving user's terminal. When it has successfully completed the connection, it also sends two bells to your own terminal to indi-
cate that what you are typing is being sent.
To set up two-way communication, the recipient of the message (user) must execute the command:
(yourterminal is only required if the originator is logged in more than once.)
Communication continues until an end of file is read from the terminal, an interrupt is sent, or the recipient executes At that point,
writes on the other terminal and exits.
To write to a user who is logged in more than once, use the terminal argument to indicate which line or terminal to send to (e.g., Other-
wise, the first writable instance of the user found in database is assumed and the following message is displayed:
terminal
...
Permission to write may be denied or granted with the command (see mesg(1)). Writing to others is normally allowed by default. Certain
commands, in particular and disallow messages in order to prevent interference with their output. However, if the user has the appropriate
privileges, messages can be forced onto a write-inhibited terminal.
If the character is found at the beginning of a line, calls the POSIX shell (see sh-posix(1)) to execute the rest of the line as a command.
The following protocol is suggested for using When you first to another user, wait for the user to back before starting to send. Each per-
son should end a message with a distinctive signal (such as "" for "over") so that the other person knows when to reply. Similarly, the
signal "" (for "over and out") can be used to indicate the end of the conversation.

write to your correspondent.
