Utility functions concerning the OCaml-runtime

val ls : string ‑> string list

val file_kind : string ‑> Core.Unix.file_kind

val groups : unit ‑> string list

Get the names of the groups the user belongs to

val hostname : unit ‑> string

val last_accessed : ?⁠follow_symlinks:bool ‑> string ‑> Core.Time.t option

last_accessed path returns the time path was last accessed. For files, the access time is updated whenever the file is read or executed. Note that some filesystems do not implement access time updates, or may allow mounting with access time updates disabled.

val last_accessed_exn : ?⁠follow_symlinks:bool ‑> string ‑> Core.Time.t

val last_modified : ?⁠follow_symlinks:bool ‑> string ‑> Core.Time.t option

last_modify path returns the time the file at path was last modified. For files, the modify time is updated whenever path is written to, or if its status attributes are updated.

val last_modified_exn : ?⁠follow_symlinks:bool ‑> string ‑> Core.Time.t

val last_changed : ?⁠follow_symlinks:bool ‑> string ‑> Core.Time.t option

last_changed path returns the time path last had its status changed. This is not the same as last modified, as the last status change will also be updated if path's ownership or permissions change.

val last_changed_exn : ?⁠follow_symlinks:bool ‑> string ‑> Core.Time.t

val file_size : ?⁠follow_symlinks:bool ‑> string ‑> Core.Int64.t option

val file_size_exn : ?⁠follow_symlinks:bool ‑> string ‑> Core.Int64.t

val scroll_lock : bool ‑> unit

scroll_lock false disables scroll locking.
