I setup some bash functions that will open applications. The code runs subl . to open the current directory in Sublime Text editor. If Sublime is already open it will open another instance of the application. Is it possible to open only that instance of the application, and close all the others? That way there are not multiple instances to juggle between.
Use the open command:
open -a 'Sublime Text' .
This uses the same LaunchServices mechanism as Finder when you click on an application, so it will only open one instance of the application.

I want to navigate using the terminal inside jupyter-lab to open up different notebooks from different locations. At the moment using $jupyter-lab file.ipynb opens up a new port in a different window, is there a way to open this within the current port?
Or even how to navigate through the terminal to a file location and then open the UI file manager in that location?
(side note) If vsCode or a different ide provides better functionality please mention as well.
Now I open jmeter using terminal using command: open /usr/local/bin/jmeter
I need it frequently, so I want to create dock icon to run this command.
How can I do it?
I tried to make a right click and choose 'keep in dock' option. However, it disappears when I close the application.
The closest I could get was creating a desktop icon through the following method:
Create a plain text document in TextEdit
Paste the following code in the document
#!/bin/bash
open /usr/local/bin/jmeter
Save the file as fileName.command
Open Terminal and navigate to the directory which you saved the file
Type in chmod +x fileName.command and hit enter
You should now have a shortcut to execute this command! I know this isn't the exact solution you were looking for, but I hope this still solves your problem.
Following E. Zimbelman's answer, you create a .command executable file and then
you can add an icon (drag and drop an icon file on the icon of the properties window of the file (Cmd+I))
change the .command extension to .app
so you can add it the the dock (drag and drop), it's ok if the icon has changed temporarily
and then you change it back to .command
With this you can have any script you like in the .command file and have it on mac's dock.
I suggest you have a look at the answer to this question in the apple stackexchange. It pretty much does exactly what you want (although I have no idea what jmeter does).
The answer is, essentially, use automator to run your script, save the automator job as an app (not a workflow), and drag the resulting object to the dock, once you have it working the way you want.

I needed a simple terminal command to unmount an internal disk which keeps spinning up whilst appearing in Finder to be unmounted. I am running the Mac from an external SSD.
All that was required was to open Script Editor and enter the text:
do shell script "diskutil eject /dev/nameofthedisk"
and then save that as an Application. Drag that to the dock and now I have one click unmounting of the disk when it spins up.
I want to set a global shortcut that will open a certain file. When there already is a gvim window that has that file open, I want it to focus on that window, and select the tab with that file. If there isn't, I want it to be opened in a new gvim window, regardless of whether there already are other gvim windows.
I can do part of this with --remote and --servername, but I can't find a way to detect whether there already is a remote server running with the name I use, so I can't quite get everything to work together to come to what I described above.
OK, turns out most can be done using the default behavior of --remote-silent. The whole setup is a matter of making an AutoHotkey script like this:
#!^+1::
Run "c:\Program Files (x86)\vim\vim74\gvim.exe" --servername org --remote-silent %DROPBOX%\org\TODO.org
WinActivate, TODO.org
Return
AHK is needed for the global hotkey as well as activating the window; vim (using --servername and --remote-silent) will start a new session called 'org' if there isn't one yet, and start it otherwise. It even gets the tab activation right when there already is a server called 'org' but if that server has another tab active.
I'm on MacOS X, and I'm pretty new to app-bundle-type things. I am writing a program that opens a window and registers mouse input -- not a command line tool. When I compile my code (written in C, if that is important) into an executable file (a "unix executable file") and then run that file directly (by double clicking it, for example), a terminal window pops up, and then the program's window pops up. Likewise, if I navigate to the directory of the executable and open it from the command line, it pops open /another/ terminal window and then the program's window.
However, if I wrap the executable in a bundle (thus, I suppose, turning it into a proper "app"), then when I run the app, either by double clicking or from the command line, the program's window opens and no new terminal window is created. Is this merely a property of the "app bundle"'s architecture? Or is there a way that I can run the raw executable without incurring another terminal window? I suspect that I'm misunderstanding something fundamental. Thanks in advance!
I believe what you're seeing is correct. In order for a separate window to not pop-up, you'd need to encapsulate it into a bundle.
Launching by double-clicking a bundle, or using the 'open' command from Terminal uses Apple's Launch Services, which maintains a list of known (registered) applications. When an application (bundle) is introduced to the system, it is registered with Launch Services and associated with its URI (e.g. com.apple.calculator), which is present in the bundle's Info.plist
Other items in the Info.plist tell launch services how to handle the application, such as checking if the minimum or maximum version of the OS has been exceeded, or whether or not to display a dock item.
A lone binary doesn't have an associated Info.plist manifest, so its behaviour can't be varied and a Terminal window is opened.
Bare executable files are essentially treated as documents by Launch Services (the framework that the Finder, Dock, and open command use when you open stuff). The application which handles such documents is Terminal. So, when you open an executable in that fashion, it launches Terminal if it's not already running and tells it to open the document. Terminal does this by opening a new shell window and auto-typing the path to the "document" as a command line.
Launch Services handles bundled apps as, well, apps. If the app is already running, it activates it and possibly has it open a new untitled window. Otherwise, it launches it.
As Rob Napier notes in the comments, if you run an executable directly from the command line (or if some already-running app launches it using NSTask or fork+exec), it will simply run. Launch Services won't be involved, so Terminal will not be asked to open the executable as a document.
I'm just meddling with OSX after a few years on Linux. There's a lot that I'm liking, but one thing that's slowing me down is that if I run the 'terminal' command via shortcut/spotlight/quicksilver, it whisks me off to any existing terminal in whatever space already has a terminal instance open.
I regularly like to pop up a terminal, run a quick command and then close it again, all the while staying in whatever desktop space I happen to be on.
...So, how do I do that on Mac?

Download this tool called Visor
It lets you quickly get a tabbed drop down terminal using a hotkey like Ctrl-`.
Insanely convenient for working in the shell.
Try this tool: https://github.com/nmadhok/OpenInTerminal
This is a really handy tool for programmers on Mac as it lets you open the folder directly in Terminal. You can select multiple folders to open them in multiple terminal windows. You can also select files to open the parent directory in Terminal. This application works with Finder as well as without Finder which is a plus!
