### Auto-Title ### Auto-Title
To auto set the terminal emulator window and tab titles with the current command To auto set the terminal window and tab titles with the current command or
or directory, add the following to *zpreztorc*:
zstyle ':prezto:module:terminal:auto-title' emulator 'yes'
To auto set the terminal multiplexer window title with the current command or
directory, add the following to *zpreztorc*: directory, add the following to *zpreztorc*:
zstyle ':prezto:module:terminal:auto-title' multiplexer 'yes' zstyle ':prezto:module:terminal' auto-title 'yes'
Auto titling is disabled inside terminal multiplexers, except inside dvtm, since
it interferes with window names defined in configuration files and profile
managers.
