Variable: tramp-histfile-override

tramp-histfile-override is a customizable variable defined in tramp-sh.el.gz.

Value

"~/.tramp_history"

Documentation

When invoking a shell, override the HISTFILE with this value.

When setting to a string, it redirects the shell history to that file. Be careful when setting to "/dev/null"; this might result in undesired results when using "bash" as shell.

The value t unsets any setting of HISTFILE, and sets both HISTFILESIZE and HISTSIZE to 0. If you set this variable to nil, however, the *override* is disabled, so the history will go to the default storage location, e.g. "$HOME/.sh_history".

This variable was added, or its default value changed, in Emacs 25.2.
