Want to use your quite a lot of disk drives extra successfully? You can via the usage of symbolic links!
Running out of disk house is unhealthy. Having a couple of disk drives and now not the usage of them to their complete attainable is worse. Some programs have personal tastes that may be modified to have data saved in any location or disk force you want.

Understanding symbolic links
A symbolic hyperlink (symlink for brief) is a sub-option of the ln Unix command that permits for the “linking” of recordsdata and directories throughout many places on a filesystem. As in step with the ln guy web page:
“The ln software creates a brand new listing access (related document) which has the similar modes as the unique document. It comes in handy for keeping up a couple of copies of a document in many puts immediately with out the usage of up garage for the
copies''; as an alternative, a hyperlinkissues” to the unique replica. There are two varieties of links; exhausting links and symbolic links. How a hyperlink “issues” to a document is one of the variations between a troublesome and symbolic hyperlink.”
A symbolic hyperlink will redirect any get admission to to it is location to the related counterpart in different places. Be it at the similar filesystem or different disk force or community location. The manner this is helping us is that via having a document or folder on Disk A pointing to a related location on Disk B, we will be able to “trick” the running machine to suppose that we’re getting access to a document on Disk Some time in truth the document lives on Disk B.
The finish result’s that you’ve necessarily load balanced your data throughout a couple of drives with out want of informing any explicit software.
Words of caution
Whenever you big name enjoying round with the underlying running machine you run the danger of critically breaking issues. Creating a foul hyperlink for an crucial folder like /lib or one thing could cause your machine to develop into inoperable.
Best use case is the desktop setting
Although you’ll carry out those adjustments on any Mac, it will be easiest observe to do it on a system that remains placed on a table. I will be the usage of an exterior disk force enclosure known as a Drobo that might be hooked up all the time as an example. If you could have a pocket book that you’re continuously bringing with you and disconnecting exterior garage, neatly, then when it comes time to get get admission to to your data, you might be disk might be lacking and also you will be unable to get admission to it. If you could have a workstation kind setting that does it is day-to-day grinding in one position, then those ideas are easiest fitted to you.
Setting up symbolic links
You’ll now want to get your palms grimy and use the terminal on macOS. If typing out instructions in now not your factor flip again now! For the remainder of you courageous souls, raise on!
In this situation, I will be appearing how to hyperlink your default “Downloads” folder to a 2nd disk force for data garage. These steps may also be replicated for any document or folder you want to hyperlink to or from.
- Start terminal.
- Type pwd to ensure that you might be in your “Home” listing,
Type du -sh * to see how a lot data is being saved in every listing and document in your house listing.
- I need to transfer the “Downloads” folder so I want to transfer the data this is already in the listing to the brand new location. I do not have already got a listing known as “Downloads” on my new disk force so we run the command cp -a Downloads/ /Volumes/Drobo/. to replica all the listing to the brand new location. You want to substitute the “/Volumes/Drobo” with what ever title you gave to the brand new location. You can on the other hand use “Finder” to replica the recordsdata over as neatly.
- Once you might be positive the replica was once a hit, you’ll delete the unique “Downloads” folder via typing sudo rm -rf ./Downloads/. You’ll be brought about for your password.
- Enter your password.
- Now we make the symbolic hyperlink via coming into ln -s /Volumes/Drobo/Downloads Downloads once more substituting your personal new location for “/Volumes/Drobo/Downloads”.
Now kind ls -al to see that the hyperlink is operating and pointing to the proper location.
- Now we restart “Finder” via going to > Force Quit to drive it to see the adjustments.
- Select Finder.
- Click Relaunch.
I’ve effectively moved my Downloads, my Documents, my iTunes backups and so on… to a separate greater disk force. Using a couple of disks immediately does build up complexity but it surely additionally will increase potency and data get admission to speeds when the usage of a couple of sources. I really like the truth that macOS has complete Unix underpinnings that provides me wonderful features and robust instructions at my disposal. How about you? How do you use the Unix underpinnings of macOS? Let us know in the feedback!
