icd

interactive cd (fast travel) in posix shell. assumes emulated terminal is vt100, see notes.

this was inspired by how fast i found i could navigate within ncdu, and was fed up with repeating cd, cd .. or .., and ls. in fact, implementing d/delete and recursive size reporting (using posix awk to parse ls and do math, or assume du) would make icd a very naive ncdu implementation without the ncurses part, or interactive du "idu", but i digress.

usage

demo asciicast

copy icd somewhere on path, source icd-wrapper, ft.

arrow keys or vi-like bindings to navigate, q to quit.

notes

posix specifies a very limited tput, so icd relies on some hardcoded vt100 escape sequences.

icd can be trivially ported to a more featureful environment, such as bash + ncurses tput, for some nontrivial compatibility (in the terminal sense) and performance improvements. examples can be found in ports/.
