In this article I assume that you already know at least a little bit about how to use AppleScript, and just want to know how to trigger a MacOS notification. At the end of the tutorial I show how to invoke the AppleScript code using Scala and Java.
If you want to copy the current macOS Terminal path to the clipboard, you can do it with this simple command:
$ pwd | pbcopy
pwd prints the path to STDOUT, and
pbcopy reads that and copies it to the macOS clipboard. Once the path is on the clipboard you can paste it into your other applications.
Of course you can also create an alias, like this:
alias path="pwd | pbcopy"
Note to self: When trying to use Pandoc to create a PDF on MacOS, you need to install MacTex separately. Install everything, because it will make things much easier later.
If you ever need to copy text (or a text file) from the MacOS Terminal to the Mac clipboard, I can confirm that the macOS
pbcopy command works. It reads from STDIN and copies the text to the clipboard, so commands like these work:
$ echo "foo bar baz" | pbcopy $ cat /etc/passwd | pbcopy
As a quick note, I often have a problem where the Messages app on MacOS (formerly Mac OS X) won’t update to receive new messages. By this I mean that I receive messages on my iPhone, but then when I go to my Mac and open the Messages app, my new text messages either never get there, or it takes a long time for them to show up in the Messages app.
As a quick note, this is a list of the IntelliJ IDEA keystrokes I use on my MacOS systems:
I just learned that MacOS has a softwareupdate command, and further learned that it has a --ignore option, which may or may not let you ignore useless updates. For example, my Mac prompts me daily to update Keynote, Numbers, and Pages, which I rarely (rarely!) use, so I don’t want to bother updating them. I’m hoping the a
softwareupdate command will help me with this.
As a quick note, I haven’t tried to log into one of my GoDaddy websites in several months, and when I tried to log in just now I got this macOS ssh error message:
Unable to negotiate with <ip-address here> port 22: no matching host key type found. Their offer: ssh-dss
I don’t have much time to explain this today, but ... if you want to see how to use the
sed command on a Mac OS X (macOS) system to search for newline characters in the input pattern and replace them with something else in the replacement pattern, this example might point you in the right direction.
As a “note to self,” I wrote two more Textmate commands yesterday, one to capitalize each word in a selection of words, and another to convert a CSV list of words to a simple list. Here’s the source code for the Capitalize command:
#!/bin/sh perl -ne 'print ucfirst $_'
$_ portion of that Perl command isn’t required, but I include it as a reminder to myself about how Textmate commands and snippets work.
Here’s the source code for my Textmate command that uses the Unix
tr command to convert a CSV list of words (such as a paragraph of comma-separated words) into a simple list of words:
#!/bin/sh tr , "\n"
As you can see, those commands are fairly simple. If you know Unix/Linux and then know a little about how to write Textmate commands, you can usually get it to do what you want. I like that you can use any Mac/Unix programming language or tool to solve the problem at hand.
