Optimising directory navigation with multiple terminals

This simple shell snippet has saved me countless keystrokes and mental context switches. It works on the assumption that most tasks are based in or around a single directory such as a Git working tree.

s() {
        pwd > ~/.saved_dir
}

i() {
        cd "$(cat ~/.saved_dir)"
}

I typically use it like this:

$ cd /srv/long/path/that/is/tricky/to/autocomplete
$ ls
one   two   three
$ s

(Switch to another terminal tab or GNU Screen window, etc.)

$ pwd
/home/lamby
$ i
$ pwd
/srv/long/path/that/is/tricky/to/autocomplete
$ ls
one   two   three

This saves me having to navigate—or even think about navigating—to the deeply nested directory.
