File locking has a long tradition in computing: you or independently running software wants to make sure that a file isn’t modified or deleted when it’s needed or in use. Because macOS is Unix based, it offers file-level permissions flags that control how a file can be manipulated and by whom.

But macOS has long had a separate way to lock a file from the Finder that also prevents it from being modified, deleted, or rename from the Terminal or other apps. Lock, unlock, and status commands are also available via the command line in Terminal.
(Note that Finder-oriented locking is entirely different from setting a file to read-only permission either in the Finder or via the Terminal, which involves changing Unix permissions. I recommend not using read-only status for files and folder you work with in the Finder and via apps, as the Finder doesn’t honor those permissions for files that are assigned to you in macOS via Unix permissions, which typically includes everything in your home directory.)
NIX users spend more time on terminal and looking for a viable option from the terminal for any purpose. This will be useful not only for me, but also for others looking for a way to do their daily activities at the terminal. Domain DNS information can be verified from the Linux terminal using the following three commands. Host Command; dig Command. Note: You can still open an external shell with the Explorer Open in Command Prompt command (Open in Terminal on Mac or Linux) if you prefer to work outside VS Code. Managing Multiple Terminals. You can create multiple terminals open to different locations and easily navigate between them. For example, you may need to rename all the files starting with the letter ‘c’ to the letter ‘d’. If you did that manually, it would take you hours. But with mmv command, multiple files can be easily renamed. To rename all the files starting with letter ‘c’ to ‘d’.
Lock and unlock via the Finder in macOS Big Sur
Turning the lock on and off in the Finder is incredibly simple. Select one file or folder and choose File > Get Info; or select multiple files or folders and hold down Option while choosing File > Show Inpector—the Option key opens a single Get Info window for the multiple items called Multiple Items Info. A Locked checkbox can be selected or deselected. It shows a – (dash) if the items selected are in a mixed state of being locked and unlocked; clicking will lock all the files.
Prior to Big Sur, locked files would have a lock image overlaid on its icon in the Finder. Big Sur only shows that lock overlay in the Get Info dialog box.
- Rename multiple items On your Mac, select the items, then Control-click one of them. In the shortcut menu, choose Rename. In the pop-up menu below Rename Finder Items, choose to replace text in the names, add text to the names, or change the. Replace text: Enter the text you want to remove in the.

Right-click the QBprint.qbp file for your QuickBooks version and select Rename. Add the word old to the file name (i.e. QBPrint.qbp.old) Open QuickBooks Desktop.
Once the file is locked, it can be moved around in the Finder, but not renamed or modified via apps. It can be deleted, but only if you confirm the operation.
Apple’s apps and those of third parties that support the convention also let you lock and unlock documents from the titlebar: click the downward-pointing arrow to the right of the file name and then select or deselect the Locked checkbox.
Using the Terminal
If you like to poke at macOS’s internals via Terminal, launch Applications > Utilities > Terminal and navigate to a folder that you’ve locked an item in. If your file is on the Desktop, you can type this to get there:
macOS reveals the lock status with a special flag on the Unix file-listing command,
ls. Enter this:
ls -lO front_door.jpeg
(That’s a capital letter O there.) You can replace
* to list everything in the directory, use another specific filename or enter a wildcard pattern, like
license*, which matches all files and folders starting with “license”. The same is true for the file name example in all the below cases.
Terminal will show you the term
uchg as a “flag” for any locked file, as in:

To lock and unlock a file in the Finder, you can directly modify that
- To lock a file:
chflags uchg front_door.jpeg
- To unlock a file:
chflags nouchg front_door.jpeg
If you want yet another method, you can use SetFile, which lets you change attributes on a file:
- To lock a file:
SetFile -a L front_door.jpeg(capital L)
- To unlock a file:
SetFile -a l front_door.jpeg(lowercase l)
