For years, I’ve been afraid of the Terminal. I was scared that I would erase my entire hard drive with a single typo.
But, then I started using grunt. I found it to be so much faster and allowed far more task automation than the tools I had been using previously. IMHO, anything that will speed up your workflow is worth investing in (whether that’s time or money ).
Once I started spending more time in the Terminal, I became more comfortable and confident. Trust me, I still prefer a GUI (graphical user interface), but I’m no longer afraid I’m going to delete my entire harddrive. — And let’s be honest, you could delete your entire hard drive with a GUI too. Drag your harddrive to the trash and click “Empty Trash.” But, nobody in the right their mind would do that. Similarly, you’d have to type a very specific command in the Terminal to delete your entire harddrive and nobody in their right mind would do that either. — Plus if you have a typo in the Terminal, it will tell you and the command won’t run.
So, here are the commands that I’ve found to be the most useful:
When you see examples of command lines in the Terminal and you see a $. Don’t copy the $, it just signifies that it’s the beginning of a Terminal line.
cd stands for change directory. Similar to the Finder where you click on the folder, in Terminal, you just type in the directory that you want:
You can type
cd .. to go up a level or
cd ../.. to go up 2 levels.
cd / will take you to your home directory.
The Terminal also supports tab auto completion. So you could type
cd De<TAB> and it will fill in
cd Desktop for you. Handy!
ls will list all files and directories in your current location.
pwd will show you the current file path to your current location.
mkdir FOLDERNAME will create a folder named FOLDERNAME.
mkdir stands for “Make Directory.”
Anytime, you hit the up arrow on your keyboard, it will fill in the last command you ran. Hit it again and it will cycle to the command before that. The down arrow cycles in the opposite direction.
Just to give you an idea of how these commands are used together: when I first open the Terminal, I might type
ls to see what my file / folder options are. Then:
$ mkdir NEWPROJECT
$ cd NEWPROJECT
This navigates to the GIT folder and then creates a new directory for a project. Then, navigates inside the folder I just created.
If this is still making your head spin, here’s a WYSIWYG way that I saved until the end: Open up your Terminal type in
cd . Then, open up Finder, navigate to the Folder you want to open in Terminal and drag that folder from the Finder onto your Terminal window. It should enter the location for that file path for you. Now, hit <RETURN>. — You’re welcome.
If you’re feeling ambitious, a few other tips and tricks:
I use iTerm2 instead of Mac’s default Terminal. It has a little bit more functionality. My favorite feature, I have a shortcut set up so that any time I hit ALT + Cmd + Space, the Terminal overlays my entire screen. Using the same command sequence will toggle it off. This is great for quickly checking on a grunt or gulp task.
If you want to set this up:
- Download and install iTerm2.
- Go to iTerm > Preferences. Click on the “Profiles” tab.
Click on the + button in the bottom left. I labeled my profile “Hotkey Window”
In the Window tab, I tweaked the transparency, checked Blur, changed the Style to “Fullscreen”, changed the Space to “All Spaces.”
Then, under the Keys tab, check “Show/hide iTerm2 with a system-wide hotkey. As I mentioned, I’m using ALT + Cmd + Space, but do whatever works best for you.
- Also check “Hotkey toggles a dedicated window with profile:” and make sure “Hotkey Window” (or whatever you named your custom profile is selected from the dropdown.
I’ve always wondered how people were able to customize their Terminal to be all kinds of cool colors.
Then, I was introduced to Oh My Zsh = Awesome.
Even if you could care less about Terminal colors, there are other short cut codes packaged within Oh My Zsh that make Terminal life even better.
I took a leap of faith and trusted Robby Russell and simply ran his automatic installer via Curl. Just copy and paste the following line into your Terminal (remember you don’t need to copy the $ sign):
Then, you can start Zsh by simply restarting or opening a new command window.
To change the theme for Oh My Zsh, copy and past the following line into your Terminal:
nano is a simple text editor that runs within the Terminal. So, we’re simply telling it to open our preference file in nano.
Go to the line that’s called ZSH_THEME=“”. Change that line to the name of the theme you want to use, in our case agnoster.
Then, type Ctrl + O for “Write Out” (also save). It will ask for the file name, just hit enter to keep the same file name.
Then, type Ctrl + X to exit.
Unzip the file. Navigate to iterm2-colors-solarized.
Double click on the Solarized Dark.itermcolors file. It should launch iTerm2 with a pop-up message explaining that the color scheme has been loaded into the iTerm2 Preferences (Preferences > Profiles > Colors > Load Presets).
Make sure your “Hotkey Window” profile is selected and choose “Solarized Dark” from the Load Presets… doprdown.
As you begin using the new theme, you may notice some of the characters are not appearing correctly.
If you’re using a font manager like Suitcase, be sure to mark the font as permanent.
If you’re still having trouble, check the Text tab within iTerm2 and make sure the appropriate fonts are marked.
UPDATE JANUARY 25, 2015
Menlo for Powerline stopped working for me. So, I ended up downloading these Powerline fonts from GitHub and installing Meslo, using the same process as described above.
As I mentioned earlier, “Oh My Zsh” has several shortcuts included. For example, if you’re running Composer, instead of typing
composer update, you can simply type
cu. Instead of
gst. Still not convinced? Here’s one of my favorites: you can type
stt and it will open the current directory within Sublime Text. These might not sound like much, but the more you live in the Terminal, the more time it will save you.
All of these shortcuts are considered plugins. You can check out all the ones that available on the Oh My Zsh’s wiki page.
Once you decide which plugins you want to use, you can activate them similar to setting the theme.
Find the line that says
Include the plugin name within the parenthesises.
I have an alias set up so that anytime I type
projects into iTerm, it will go directly to my projects folder, where I keep all my code. Essentially, it’s the same as typing
cd ~/Code/GIT/ (just in case you were wondering the ~ references your home directory. If you’re not sure what I’m referring to, just type
cd ~ and then
ls in the Terminal. You’ll see.)
If you still have your preference file open (
nano ~/.zshrc ), look at the bottom. There are a few examples already set up, but commented out (the # in front means the line is commented out). Add a line at the very bottom, below the examples, that reads
alias projects="cd ~/Sites".
Then, write out the file (^O) and exit (^X). Restart iTerm2 (or open a new command window). Test it out. Nifty!
