I lost the script (bash function) when I changed job, but inspired by a co-worker:
> up
Does a `cd ..` on every keypress except ESC or space.
> up $n
Does a total of $n `cd ..` and (important!) set OLDPWD to the initial directory for proper `cd -`.
- whetu 4y agoI've seen a few examples of this function over the years, here's a recent variant of mine (I'm accepting the use of eval here): # Provide 'up', so instead of e.g. 'cd ../../../' you simply type 'up 3' up() { case "${1}" in (*[!0-9]*) : ;; ("") cd || return ;; (1) cd .. || return ;; (*) cd "$(eval "printf -- '../'%.0s {1..$1}")" || return ;; esac pwd }
