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
Type “xfoo” … READ THE REST

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
