- **Package:** libtmux-haskell
- **Language:** Haskell
- **Kind:** function
- **Source:** https://github.com/libtmux/libtmux-haskell/blob/663e212622a02aa74a9bdc8ff71e2b45fcb1d4d5/src/LibTmux/Server.hs#L208

```haskell
renameWindow :: Server -> WindowRef -> TmuxText -> IO ()
```

Signature types: [`Server`](/en/haskell/latest/reference/libtmux-server-t-server/), [`WindowRef`](/en/haskell/latest/reference/libtmux-snapshot-t-windowref/), [`TmuxText`](/en/haskell/latest/reference/libtmux-snapshot-t-tmuxtext/), [`IO`](https://hackage.haskell.org/package/base-4.22.0.0/docs/Prelude.html#t:IO).

Rename one physical window across all its session links. The label retains
 bytes through [`TmuxText`](/en/haskell/latest/reference/libtmux-snapshot-t-tmuxtext/); tmux may reject names its release does not accept.
 Format-looking text stays literal. See [`renameWindowWith`](/en/haskell/latest/reference/libtmux-server-v-renamewindowwith/) for a deadline.
