A fast, compact TUI for directory navigation and bookmark management.

bmrk is a compact inline TUI that fits in 8 rows and never takes over your terminal screen. Navigate directories, manage bookmarks, search for folders and files — all from the keyboard.

The binary is bmrk. The shell wrapper bm wraps it and handles cd automatically — because a process cannot change its parent shell's directory, a thin wrapper is required (the same approach used by fzf, zoxide, and autojump).

• Compact inline mode — 8 rows, no fullscreen takeover, terminal fully restored on exit
• Bookmarks — save and jump to favorite directories; bm myproject navigates instantly
• Interactive tree view — directory navigation with expand/collapse
• Fuzzy search — fast asynchronous search with intelligent matching
• Disk selection — browse and switch between all drives/mount points (d key)
• Mouse support — click, double-click, scroll
• Customizable — TOML configuration with theme presets and custom colors

From crates.io:

cargo install bmrk

From source:

git clone https://github.com/holgertkey/bmrk.git
cd bmrk
cargo build --release

The binary is at target/release/bmrk (Linux/macOS) or target\release\bmrk.exe (Windows).

The repository includes three ready-made wrapper files. Each one integrates bmrk with a specific shell so that cd works correctly. Pick the file that matches your environment.

What it does. bm.bat is a batch script that runs bmrk.exe and redirects its stdout to a temporary file. If the captured output is a valid directory path, it calls cd /d to change the current session's directory. Non-directory output (help text, version, bookmark lists) is printed as-is. The previous directory is saved in %BMRK_PREV_DIR% so that bm - can return to it. Flags that do not trigger navigation (-h, --help, -v, --version, -l, --list, -a, --add, -c, -d, --del) are passed straight through to bmrk.exe.

Installation:

1. Copy bmrk.exe and bm.bat to the same directory that is on your PATH (e.g. C:\Users\<YourName>\bin\).

2. If that directory is not on your PATH yet, add it and open a new CMD window:

   setx PATH "%PATH%;C:\Users\<YourName>\bin"
   

3. Test:

   bm --version
   bm
   

What it does. bm.ps1 defines a bm function for PowerShell. It runs bmrk.exe, captures stdout to a temporary file, and calls Set-Location if the result is a valid directory path. The previous directory is stored in $env:BMRK_PREV_DIR for bm - support. Pass-through flags (-h, --help, -v, --version, -l, --list, -a, --add, -c, -d, --del) are forwarded directly to bmrk.exe without any cd logic. Compatible with Windows PowerShell 5.1 and PowerShell 7+.

Installation:

1. Copy bmrk.exe to a directory on your PATH (e.g. C:\Users\<YourName>\bin\).

2. Open your PowerShell profile for editing:

   notepad $PROFILE

   If the file does not exist yet, create it first:

   New-Item -ItemType File -Force $PROFILE

3. Add the following line to your profile:

   . "C:\path\to\bmrk\bm.ps1"

4. Reload the profile:

   . $PROFILE

5. Test:

   bm --version
   bm

What it does. bm.sh defines a bm function for POSIX-compatible shells (bash and zsh). It runs bmrk via command substitution, captures stdout, and calls cd when the result is a valid directory. The previous directory is stored in $BMRK_PREV_DIR for bm - support. Any output that is not a directory path (help text, version, bookmark list) is echoed to the terminal unchanged. For fish, use bm.fish instead (see below).

Installation — bash:

1. Copy the bmrk binary to a directory on your PATH:

   cp target/release/bmrk ~/.local/bin/
   # or: sudo cp target/release/bmrk /usr/local/bin/

2. Source the wrapper from your shell config:

   echo 'source /path/to/bmrk/bm.sh' >> ~/.bashrc

3. Reload and test:

   source ~/.bashrc
   bm --version
   bm

Installation — zsh:

Same steps as bash, but add to ~/.zshrc instead of ~/.bashrc.

What it does. bm.fish defines a bm function for fish. Fish uses its own function-file format and cannot source bm.sh directly, so this is a separate file. It runs bmrk, captures stdout, and calls cd when the result is a valid directory. The previous directory is stored in $BMRK_PREV_DIR for bm - support. Any output that is not a directory path (help text, version, bookmark list) is echoed to the terminal unchanged.

Installation:

1. Copy the bmrk binary to a directory on your PATH:

   cp target/release/bmrk ~/.local/bin/
   # or: sudo cp target/release/bmrk /usr/local/bin/

2. Copy or symlink bm.fish into fish's functions directory:

   cp /path/to/bmrk/bm.fish ~/.config/fish/functions/bm.fish
   # or, to keep it in sync with the repo:
   ln -s /path/to/bmrk/bm.fish ~/.config/fish/functions/bm.fish

3. Fish picks up functions in that directory automatically — no reload step needed. Test with:

   bm --version
   bm

bm                          # Open interactive TUI (compact, 8 rows)
bm /path/to/dir             # Open TUI at specific directory
bm myproject                # Jump to bookmark (cd directly, no TUI)
bm myproject/src/app        # Jump into a sub-directory of a bookmark
bm -                        # Return to previous directory

# Bookmark management
bm -l                       # List all bookmarks
bm -a work                  # Save current directory as 'work'
bm -a work /some/path       # Save specific path as 'work'
bm -d work                  # Remove bookmark 'work'

bm -v / --version           # Print version
bm -h / --help              # Print help

Config file is created automatically on first run:

• Linux/macOS: ~/.config/bmrk/config.toml
• Windows: %APPDATA%\bmrk\config.toml

Bookmarks are stored as bookmarks.json in the same directory. A background-built directory index cache lives alongside them as dir_index.txt — it's a performance optimization, not user data, so it's safe to delete to force a rebuild.

bmrk writes its TUI to stderr (visible in the terminal) and the selected directory path to stdout. The wrapper captures stdout via a temp file (CMD: set /p; PowerShell/bash: $t):

• If captured output is a valid directory path → cd to it (saves previous dir for bm -)
• If output is empty (Esc pressed) → do nothing
• Otherwise → print the output as-is (help, version, bookmark list)
