私は何が間違っていましたか？マニュアルページの指示に従っていると思いますが、何の効果もありません。

これはApple特有の現象のようです。 （私はMac OS 10.11.6 El Capitanを使用しています。）
私のHISTFILE価値観は直接的な原因です。
[512] $ echo $HISTFILE
/Users/Wildcard/.bash_sessions/8BC6B122-0D74-445B-B6A0-7D4D446598CB.historynew
ところで、その変数を設定しなかったので、どこに設定されていますか？
ああそうだね..コメントを見たら私が設定もしなくて自分で試してみる/etc/bashrc_Apple_Terminalと偶然出会ったようですね。 histappendをオンにするか、HISTTIMEFORMAT変数を設定すると、セッション再開サポートコードをスキップするようにコーディングされました。history -ashopt -s histappend
このセクションのインライン文書は次のとおりです。
# Resume Support: Save/Restore Shell State
#
# Terminal assigns each terminal session a unique identifier and
# communicates it via the TERM_SESSION_ID environment variable so that
# programs running in a terminal can save/restore application-specific
# state when quitting and restarting Terminal with Resume enabled.
#
# The following code defines a shell save/restore mechanism. Users can
# add custom state by defining a shell_session_save_user_state function
# that writes restoration commands to the session file at exit. e.g.,
# to save a variable:
#
# shell_session_save_user_state() { echo MY_VAR="'$MY_VAR'" >> "$SHELL_SESSION_FILE"; }
#
# During shell startup the session file is executed. Old files are
# periodically deleted.
#
# The default behavior arranges to save and restore the bash command
# history independently for each restored terminal session. It also
# merges commands into the global history for new sessions. Because
# of this it is recommended that you set HISTSIZE and HISTFILESIZE to
# larger values.
#
# You may disable this behavior and share a single history by setting
# SHELL_SESSION_HISTORY to 0. There are some common user customizations
# that arrange to share new commands among running shells by
# manipulating the history at each prompt, and they typically include
# 'shopt -s histappend'; therefore, if the histappend shell option is
# enabled, per-session history is disabled by default. You may
# explicitly enable it by setting SHELL_SESSION_HISTORY to 1.
#
# The implementation of per-session command histories in combination
# with a shared global command history is incompatible with the
# HISTTIMEFORMAT variable--the timestamps are applied inconsistently
# to different parts of the history; therefore, if HISTTIMEFORMAT is
# defined, per-session history is disabled by default.
#
# Note that this uses PROMPT_COMMAND to enable per-session history
# the first time for each new session. If you customize PROMPT_COMMAND
# be sure to include the previous value. e.g.,
#
# PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND; }your_code_here"
#
# Otherwise, the per-session history won't take effect until the first
# restore.
#
# The save/restore mechanism is disabled if the following file exists:
#
# ~/.bash_sessions_disable
