In addition to those `*PAGER` environment variables, the behavior of `less` is also affected by the `LESS` environment variable (see `man less` or [online documentation](https://linux.die.net/man/1/less)). This env var can contain command line options and/or interactive less-commands (prefixed by a leading `+` sign; these are executed every time right after less is launched). -In addition to `DELTA_PAGER`, and `PAGER`, delta currently also consults `$BAT_PAGER` (with priority between the two). -However, this is deprecated: please use `DELTA_PAGER` instead. -No other [`bat`](https://github.com/sharkdp/bat) environment variables are used by delta, and delta does not use `bat` when it is running (it does use some code from the excellent `bat` project, but users don't need to be aware of this). - ## Delta-specific environment variables To temporarily activate and inactivate delta features, you can use `DELTA_FEATURES`, e.g. |
