bd

Navigate to parent directories by name

TLDR

Go back to a parent directory by name (or its first few letters)

$ bd [name]

Case-sensitive match

$ bd -s [name]

Run a command in a parent directory without changing to it

$ ls `bd [name]`

bd (back directory) is a bash utility for quickly navigating to a parent directory by name instead of typing multiple `cd ../../../` commands. It searches upward in the current path for a directory whose name matches (matching on the first few letters is enough).If several ancestors share the same name, bd jumps to the closest one (the immediate parent is not considered a match). It is installed as a shell alias so the directory change persists in your shell:

$ alias bd=". bd -si"

PARAMETERS

-s

Case-sensitive matching (the default alias uses -si for case-insensitive).

-i

Case-insensitive matching (no-op when already the default).

WORKFLOW

$ # Current path: /home/user/projects/myapp/src/components
# Jump up to 'myapp'
bd myapp
# Now in: /home/user/projects/myapp

# Or just the first letters
bd my

# Use a parent path inline without leaving the current directory
cp file.txt `bd projects`

FEATURES

- Prefix matching on parent directory names- Bash completion support (via the bundled completion file)- Closest-match resolution when names repeat in the path

INSTALL

yay -S bd

CAVEATS

Requires installation and an alias in your shell config (the alias sources the script so the `cd` sticks). Only walks upward through the current path, not into sibling trees. Built for bash; separate ports exist for zsh and fish. Not available by default on most systems.

HISTORY

bd was created by Vigneshwaran Raveendran (vigneshwaranr) to simplify navigating up directory trees by name.
