# Environment

`$SYSTEMD_PAGER`

  Pager to use when `--no-pager` is not given; overrides `$PAGER`. If neither `$SYSTEMD_PAGER` nor `$PAGER` are set, a set of well-known pager implementations are tried in turn, including less 1 and more 1, until one is found. If no pager implementation is discovered no pager is invoked. Setting this environment variable to an empty string or the value `cat` is equivalent to passing `--no-pager`.

`$SYSTEMD_LESS`

  Override the options passed to `less` (by default `FRSXMK`).

`$SYSTEMD_LESSCHARSET`

  Override the charset passed to `less` (by default `utf-8`, if the invoking terminal is determined to be UTF-8 compatible).
