Quick open files of a certain type

Quick open files of a certain type

I’m not spending £19 an Alfred for just this one purpose, but for its seemingly endless uses that improve productivity. In this example, I’ll create a shortcut to open Xcode projects and workspaces.

Requirements

  • A utility application called Alfred
  • Purchasing the Powerpack for £19

Setup

  • Open Alfred Preferences
  • Click on Workflows
  • Click on the button at the bottom of the sidebar
  • Choose Templates > Files and Apps > File filter from keyword and open
  • Give it a name like “Open Xcode Project” and click OK
  • Double-click on File Filter
  • Enter “x” in the keyword field and uncheck “with space” (unchecked, this means the space is optional)
  • In the File Types field, click the button and navigate to an xcodeproj file
  • Optionally, do the same with an xcworkspace file

Optionally, you can click on the Search Scope tab and restrict the search to one or more directories.

Now, bring up Alfred

Simple repeating command-line command

Simple repeating command-line command

Rather than write a script for something you may only need once, there’s an easy way to repeat a series of command-line commands. This works in bash and may in other shells:

while [ 1 ]; do <some command>; <some other command>; sleep <some delay in seconds>; done;

So, for example:

while [ 1 ]; do date; uptime; sleep 10; done;
This will generate:
Mon Mar 19 13:20:30 PDT 2018
13:20 up 1:23, 3 users, load averages: 3.25 3.87 3.51
Mon Mar 19 13:20:40 PDT 2018
13:20 up 1:24, 3 users, load averages: 3.31 3.86 3.51
Mon Mar 19 13:20:50 PDT 2018
13:20 up 1:24, 3 users, load averages: 5.44 4.30 3.67

Just use Ctrl-C to end.

Extra credit

Add a counter so that it runs 10 times only:

for n in $(seq 1 10); do date; uptime; sleep 10; done
