tmux-file-picker

Pop up fzf in tmux to quickly insert file paths, perfect for AI coding assistants like Claude Code.

Installation

Download the script:

curl -O https://raw.githubusercontent.com/raine/tmux-file-picker/main/tmux-file-picker

Make it executable:
```
chmod +x tmux-file-picker
```
Move it to a directory in your PATH:
```
mv tmux-file-picker ~/.local/bin/
```

Dependencies

fzf: For the fuzzy-finding interface.
fd: For file discovery.
bat (optional): For syntax-highlighted file previews.
zoxide (optional): For the --zoxide flag to select directories from your frecent list.
tree (optional): For better directory previews when using --zoxide.

macOS users: The script uses grealpath for path resolution. Install it via Homebrew:

Setup

Add a key binding to your ~/.tmux.conf to launch the file picker. When triggered, it opens an fzf interface in a popup overlay, letting you select files without leaving your current session.

Choose from the examples below based on your workflow:

# ~/.tmux.conf

bind C-f display-popup -E "tmux-file-picker"

# Use -g flag to show paths relative to git root
bind C-g display-popup -E "tmux-file-picker -g"

# Use --directories to select directories instead of files
bind C-d display-popup -E "tmux-file-picker --directories"

# Use --zoxide to select from your frecent directories first
bind C-z display-popup -E "tmux-file-picker --zoxide"

# Use --zoxide with --dir-only to just insert the directory path
bind C-v display-popup -E "tmux-file-picker --zoxide --dir-only"

# Combine --zoxide with --git-root
bind C-x display-popup -E "tmux-file-picker --zoxide --git-root"

# Popup dimensions can be configured like this:
# bind C-f display-popup -h 60% -w 60% -E "tmux-file-picker"

Reload your tmux configuration for the changes to take effect: tmux source-file ~/.tmux.conf

Usage

While typing a message to your AI assistant, press your configured tmux key binding (Ctrl-f in the example above).
An fzf window will pop up, listing all files in the current directory.
Type a few characters to filter the list and find your file.
Press Enter to select one file, or Tab to select multiple files.
The selected file path(s) will be pasted directly at your cursor position.

Searching a specific directory

You can pass a path as an argument to search a specific directory instead of the current pane directory:

# Search in a specific directory
bind C-d display-popup -E "tmux-file-picker ~/my-project"

# Combine with --git-root flag
bind C-y display-popup -E "tmux-file-picker --git-root ~/my-project"

Both absolute and relative paths are supported. Relative paths are resolved relative to the current pane directory.

Note: If your path contains spaces, it must be quoted inside the command string:

# Example with a quoted path containing spaces
bind C-d display-popup -E "tmux-file-picker '~/my projects/project a'"

Using zoxide for directory selection

The --zoxide flag lets you interactively select a directory from your zoxide frecent directories before picking files:

tmux-file-picker --zoxide
# First: fzf shows your zoxide directories
# Second: fzf shows files from the selected directory
# Returns absolute paths (e.g., /home/user/project/src/file.ts)

This is particularly useful when you frequently switch between different projects. When using --zoxide, the script returns absolute paths instead of relative paths, making it easier to reference files from any directory.

Directory-only mode

Use --dir-only with --zoxide to insert just the directory path without the file selection step:

tmux-file-picker --zoxide --dir-only
# Only shows directory selection, skips file picking
# Useful for quickly inserting project paths

Selecting directories

Use --directories (or -d) to select directories instead of files:

tmux-file-picker --directories
tmux-file-picker -d

# Can be combined with other flags
tmux-file-picker -d --git-root

The preview shows a tree view of each directory (falls back to ls if tree is not installed).

Customizing fd flags

You can customize the file discovery behavior by setting the TMUX_FILE_PICKER_FD_FLAGS environment variable. The default is -H --type f --exclude .git (show hidden files, only files, exclude .git directory).
