Demonstrates using the Z program for quickly jumping between directories.
# Hello and welcome to the Alchemists Screencasts! # Today, we'll look at adding Z (https://github.com/rupa/z) to your toolbox. # Let's say we have the following directory structure: one="$(mktemp -d -t one)" && printf "%s\n" "$one" two="$(mktemp -d -t two)" && printf "%s\n" "$two" three="$(mktemp -d -t three)" && printf "%s\n" "$three" # Granted, these are temporary directories you'd not use in a typical workflow. # However, they demonstrate long paths which are a pain to type out. # For example, let's visit the first directory we created:
cd /var/folders/lp/ptcmr94j0fn366vw8cczw5s00000gn/T/one.tw3PwX1f # Ugh, that was time consuming. 😅 # ← By the way, my shell is configured to *only* show the parent directory. # To confirm, here's the full path of our current directory: pwd # What if we wanted to visit the second directory we created? # We could cheat, since we have that path stored in the `$two` variable: cd "$two" # What if we wanted to work in the third directory? # By this time, we've probably forgotten what that path was. # Since they are local variables, we can at least print them out again: set | ag --nocolor "(one|two|three)=" # OK, good, now we can change directory to `$three`: cd "$three" # That's a lot of cognitive load to keep in our mental stack. # This is where Z comes into play. # Instead of using `cd`, we can use `z` instead: z var one z var two z var three # Because these are temporary directories, I need to supply the "var" path prefix. # This gives Z more *specificity* to intelligently jump to the desired path. 😉 # This doesn't happen for *normal* paths. Example: z Downloads z demo # To install Z, run the following: brew install z # Additional documentation for setting up your environment can be found here: # https://github.com/rupa/z # I'd recommend adding this to your `.bashrc` file, though: cat $HOME/.bashrc | ag --nocolor --after=4 "# Z" # Note the use of the `$_Z_DATA` environment variable. # I use this to adhere to the XDG specification: https://alchemists.io/projects/xdg. # ...which prevents my $HOME directory from being cluttered. 🎉 # I even define a `ze` alias for editing the Z cache so-to-speak: cype ze # Comes in handy for times when you want to make modifications to what Z is tracking. # Hopefully this gives you another tool in which to speed up your workflow. 🎉 # Enjoy! # https://alchemists.io # ☿ 🜔 🜍 🜂 🜃 🜁 🜄
