Acquires sessions through [`-Server`](/en/powershell/latest/reference/libtmux-get-tmuxsession/#LibTmux%5CGet-TmuxSession.parameter.Server), with optional exact [`-Id`](/en/powershell/latest/reference/libtmux-get-tmuxsession/#LibTmux%5CGet-TmuxSession.parameter.Id) and [`-Name`](/en/powershell/latest/reference/libtmux-get-tmuxsession/#LibTmux%5CGet-TmuxSession.parameter.Name) selectors. |
| Julia | [`LibTmux.sessions`](/en/julia/latest/reference/libtmux-sessions/) (function). `sessions` reads membership from a captured `Snapshot` without contacting tmux. |
| Elixir | [`LibTmux.Snapshot.sessions/1`](/en/elixir/latest/reference/libtmux-snapshot-sessions-1/) (function). Returns a `Selection` of captured sessions without contacting tmux. |
| Haskell | No public Haskell equivalent is implemented; the current modules expose scalar values and version parsing. |
| Common Lisp | [`libtmux:sessions`](/en/lisp/latest/reference/libtmux-sessions/) (function). `sessions` returns a fresh vector from a captured snapshot without contacting tmux. |

| F# | [`LibTmux.FSharp.Server.sessions`](/en/fsharp/latest/reference/libtmux-fsharp-server-sessions/) (function). Builds a deferred session query on `LibTmux.Server`. `Query.list` acquires the results; it does not traverse the handle’s captured membership. |
