Mac Os X Library Path
- (MAC OS X) How to Load a Java Native/Shared Library (.jnilib) There are several ways to make it possible for the Java runtime to find and load a native shared library (.jnilib) at runtime.
- Mac OS X doesn’t have an obvious way to view the exact text based path to a folder (otherwise known as a directory) in the finder window. You can have it show a graphical path, but getting just the text based path to a directory (for use in the Terminal for example) requires a couple of extra steps.
Feb 18, 2011 I've tried repeatedly installing jzmq on Mac OS X. Whatever I do, I hit a brick wall with this exception: java.lang.UnsatisfiedLinkError: no jzmq in java.library.path I have successfully installed (pkg-config and) libzmq and libjzmq into.
Just like the Windows operating system, the MacOS operating system has a hidden Library folder full of settings you shouldn’t really touch. Deleting some or all of these settings will at best force you to reinstall certain apps, and at worst, cause the whole system to collapse and require a complete reinstall.
But there may be times when accessing the Library folder is necessary. For example, many apps put backups in the Library folder and you may want to back up the backup. Or you might be customising your Mac, which will need access to certain library folders.
Here is how to get there and not cause your Mac to collapse in a cloud of dust in the process.
What Is The Library Folder On MacOS?
The library folder is the area of your MacOS computer where app settings are stored. When you install a program, a folder is created in the Library for all of the essential settings. This can be anything from plugins, preference files and log files.
It’s hidden because basically some people are just plain clumsy and quite often don’t know what they are deleting. It’s only when it’s too late when they realise that something they just deleted should have been kept.
So you could say that Apple is protecting you against your own worst impulses!
How To Find The Hidden Library Folder On MacOS
There are two ways to get to the hidden Library folder if you are confident enough of not triggering a nuclear apocalypse. But the second way is only really feasible when you know where to look.
Unhide library folder mac mavericks 2017. Mar 12, 2020 If you don’t mind using Terminal on your Mac, you can unhide the Library folder with a simple command. Open Terminal from the Applications Utilities folder or using Spotlight. Copy and paste or enter the following commands, on separate lines, and hit Return when you finish. How To: Unhide User Library Folder Mac OS 10.9 Mavericks Open a window in the Finder. Select you user folder (mine: joes10) or if your User Folder is not in the sidebar, while in the Finder hit ⇧⌘H to open directly to your User Folder. Select menu: View Show View Options or hit ⌘J.
First Method (The Easiest)
Go to Finder and drop down the “Go” menu. You’ll see that the Library folder is not listed.
To make the Library folder appear, press the “Alt” key (also known as the Option key) at the bottom left of your keyboard. The Library folder will now appear.
Click on the Library folder option to be taken straight to the folder.
The problem though with this method is that this is very temporary. As soon as you take your finger off the alt key, the Library folder will disappear again.
Second Method (Not Difficult)
Once you know the path to the folder (by following the previous method), you can then use the path to go directly to the Library folder.
At the top of the Library folder, you will see the exact path (location) of the folder on your computer.
I have covered over my username in the screenshot, but the path is :
With that in mind, go back to Finder’s Go menu and at the bottom, you’ll see this option :
Choosing “Go to Folder” will bring up a box where you can type the path to the Library folder. Hitting the “enter” key will then take you straight there.
Even better, until you input the path to a different folder, the path to the Library will remain in the “Go to Folder” box.
When it is gone, dropping down the menu arrow on the right hand side will show you a list of previous folders you went to, and the Library one will be there too.
Conclusion
There used to be a way to keep the Library folder showing permanently. But as of High Sierra, the Terminal command no longer seems to work.
However, keeping the folder permanently visible isn’t a good idea since you might delete a system-critical file. Besides, as you have just seen, it is not difficult at all to go to the folder when you need it.
The shell path for a user in macOS or OSX is a set of locations in the filing system whereby the user has permissions to use certain applications, commands and programs without the need to specify the full path to that command or program in the Terminal. This will work in macOS Mojave, Sierra and all older OSX operating systems; El Capitan, Yosemite, Mavericks and Lion.
So instead of running something like this, with a path to the command:
You can just type the command, regardless of where you are in the filing system:
Your shell path is a bunch of absolute paths of the filing system separated by colons :
You can find out whats in your path by launching Terminal in Applications/Utilities and entering:
And the result should be like this…
So this is stating that you can run Unix style applications or commands located in 5 default locations of a certain path in the filing system:
- /usr/bin
- /bin
- /usr/sbin
- /sbin
- /usr/local/bin
These directories are not visible by default in the filing system but you can make them visible.
Adding a Temporary Location
Mac Os X Library Path 2017
You can add extra locations to your path, in the mysql example above it’s location /usr/local/mysql/bin which is not in the default path, you can add it in Terminal like so:
So here I have copied my existing path and added the new location on the end. Test it by running echo $PATH again in the Terminal.
One of the disadvantages of this is that the new location will only be honored for that particular Terminal session, when a new Terminal window is launched it will have the original default path again.
Adding in a Permanent Location
Mac Os X Library Path 2
To make the new pathstick permanently you need to create a .bash_profile file in your home directory and set the path there. This file control various Terminal environment preferences including the path.
Move into home directory
Create the .bash_profile file with a command line editor called nano
Add in the above line which declares the new location /usr/local/mysql/bin as well as the original path declared as $PATH.
Save the file in nano by clicking ‘control’ +’o’ and confirming the name of the file is .bash_profile by hitting return. And the ‘control’+’x’ to exit nano
So now when the Terminal is relaunched or a new window made and you check the the path by
You will get the new path at the front followed by the default path locations, all the time
Rearranging the default $PATH
If you needed to rearrange the paths in the default $PATH variable, you can just do that and leave off $PATH.
So lets say you want /use/local/bin at the beginning to take precedence you can add the default path like so inside .bash_profile
Mac Os Path Variable
And then you can slot in other paths as required.
