The start of 2014 has been an exercise in going back to basics for me. I’ve been re-evaluating my workflows when hacking and attempting to streamline as much as humanly possible. This has resulted in a ton of new aliases in an attempt to get my common CLI commands down to 2 or 3 characters as well as the adoption of a ton of new commands that I wasn’t even aware of a month ago. There has also been a ton of rework to my
vim configuration, but I’ll save that for another post.
aliases are absolutely my favorite way to save keystrokes and often times allow me to cut out the thought process when trying to remember how to run some complex command that I only run into a few times a year. I’ve been a
zsh user for some time now and
oh-my-zsh has a ton of plugins that provide you with a ton of aliases but I’ve some of my aliases predate my
zsh usage and some of the aliases provided just aren’t as short / intuitive as I’d like them to be.
Here’s a few of my favorite aliases right now:
alias mcfl="echo 'flush_all' | nc localhost 11211"
Unquarantine all the files in an OSX directory:
alias unquarantine="xattr -r -d com.apple.quarantine *"
git repo using the currently checkout branch name:
alias gp="git rev-parse --abbrev-ref HEAD | xargs git push origin"
Alias commands like
HEAD on OSX:
for method in GET HEAD POST PUT DELETE TRACE OPTIONS; do alias "$method"="lwp-request -m '$method'" done
You can check out all of my aliases in my zshrc.
hub command is a
gem for interfacing with GitHub. It’s actually not something I use a ton of but I do love it so. The main reason I started using it is because it has the ability to easily clone a GitHub repository without needing the full clone URL:
hub clone joshtronic/dotfiles
dotfiles directory is created and everything is cloned into it. If nothing else it saves some keystrokes. I had written a
git script to do something similar a while back and was happy to drop it from my
dotfiles. I plan to explore the
hub command more in the future as I read that aliasing
hub is a pretty fantastic thing.
You can find out everything about
hub on the official site.
GitHub Issues from the CLI
hub but the only reason I discovered it is because I was on the hunt for a way to handle GitHub Issues from the command line. Turns out that
hub doesn’t do that but another
gem that does.
ghi allows you to view your open issues, create new ones, and all of that good stuff right from the CLI!
To make things even easier, I set up aliases for my common issue labels Development, Enhancement and Bug. I generally stick to those 3 labels because that’s all I really need to organize and I only ever assign one label to an issue.
Development is anything brand new that needs to be built. Enhancement is development against an existing piece of code. Bug well that should be obvious. I
ob to show me open issues for each type and
nb to open a new issue.
GitHub’s a pretty speedy site, but CLI interfacing is a faster workflow for me. OH did I mention you get to use your favorite
$EDITOR? Anytime I can work in
vim is a blessing. The source code and details about
ghi are available here.
Not too long ago I started to coerce my buddy Justin Davis into being a CLI-ninja and more recently he asked me about my prompt, specifically the josh@nemo that was on there. I was taken back by this because I had never given much thought as to why I needed not only my name on every damn line but also the name of my local machine. It makes sense on a remote server but even then, the only time I need
whoami is when I’m not me.
Fast forward to last week when I decided to rework my
zsh theme. I dropped the time from my prompt (as well as on my OSX menu bar, yet again) and added some logic to selectively show the username and server name. Whenever I am logged in as myself, I no longer see my username and as long as I’m on a machine that’s
hostname ends in “.local” I won’t see the server name either.
My current prompt is still 2 lines as I favor the consistency of my commands always starting in the same spot. The first line is the
pwd in blue,
git branch in yellow and a red ✗ if the
git repo is dirty. There was no need to show a green ✔ (like I see on some prompts) because a clean repo doesn’t have a pending action item (committing). Second line is the prompt itself in grey. The hardest thing to get over is the lack of time but that’s definitely helped keep me tunnel visioned on the task at hand.
zsh theme is available in my dotfiles.
Adding an email indicator to my
Over the last few months I’ve been juggling email clients continually going back to Gmail’s web interface. It works but all of the new email indicators I’ve ran into would alert on every single new email and that’s not ideal as it’s a unecessary distraction while trying to code. I also wanted to be able to see my number of unread messages from the command line as that’s where I spend the majority of my time on the computer.
To solve these pain points, I developed a very small script (so many pipes!) that checks Gmail from the command line by leveraging the OSX Keychain for security as most solutions I found included storing those credentials in plaintext which is not ideal at all. Once I was able to grab the unread count, I set it up in
launchd to run every 5 minutes and my
zsh prompt to show a 📩 in the
RPROMPT if and only if there are 5 or more unread messages. At this point I had decided that having the actual count shown wasn’t really necessary.
You can use
crontab if you’d like but from what I read on OSX
crontab is just an interface for
launchd and I had never written a plist file so figured I’d give it a go.
Speaking of email, all of my trials and tribulations with Mail.app and my quest for the perfect email client that supports Gmail eventually led me to
mutt. I’m still getting into the swing of things with it but like many things, it’s just amazing to be able to get so much done without leaving the comfort of my terminal.
mutt to work with Gmail was pretty painless as I found a sample config in a LifeHacker article. Like many of the articles I’ve ran into, it relied on plaintext storage of your login credentials. Fortunately,
mutt’s config allows you to assign variables with the results from backticked commands. OSX Keychain made another appearance in my
My next step with
mutt is to get multiple accounts working as I have both a Gmail account and a Google Apps account. From my reading thus far, you end up having to switch profiles or something like that. Doesn’t sound too bad but will probably result in a small change to my email indicator so I know which account I will need to be checking. If I had the time, I’d fork the source and hack it to show all of my email in a single view (a la Mail.app). I also need to work out a colorscheme. I’m using
mutt but I’d much rather use
jellybeans as I’m using it in
vim and as my iTerm2 theme. Good chance I’ll port
mutt this week ;)
muttrc is available in my dotfiles as well. Since it doesn’t contain any login credentials, you should be able to use it as is, just be sure to set up a new Keychain item named “@gmail” to house your account credentials.
I understand that the command line isn’t for everyone, but it is for me. It actually makes me wonder why I even run OSX and why I just don’t go back to Xmonad. What are my next steps on the CLI? At the moment I think I’m at a point that I’m polishing what I have and probably won’t be making any major additions for a while. That could change the moment I stumble across some hot new command though. Maybe someone reading this could suggest some? Comment below!
