+Due to the remote shell saving tilde expansions triggered by
+@value{tramp}, the history file is probably growing rapidly.
+@value{tramp} can suppress this behaviour with the user option
+@code{tramp-histfile-override}.  When set to @code{t}, environment
+variable @env{HISTFILE} is unset, and environment variables
+@env{HISTFILESIZE} @env{HISTSIZE} are set to 0.
+
+Alternatively, @code{tramp-histfile-override} could be a string.
+Environment variable @env{HISTFILE} is set to this file name then.  Be
+careful when setting to @file{/dev/null}; this might result in
+undesired results when using @command{bash} as remote shell.
+
+Another approach is to disable @value{tramp}'s handling of the
+@env{HISTFILE} at all by setting @code{tramp-histfile-override} to
+@code{nil}.  In this case, saving history could be turned off by
+putting this shell code in the @file{.bashrc} or @file{.kshrc} file:
