Tread thoughtfully and deliberately, and always remember to use the ‘ man‘ command to get details if you’re unsure. The Terminal can be both handy and efficient, not to mention fun. “/Volumes/Back Seat Betty/usr/bin/du” -sh *
My hard drive is named “Back Seat Betty” because I name all my drives after Miles Davis songs, so for me that command would be: If your hard drive name contains a space, it’s safer to wrap the whole thing in double quotes as I have just to make life easier. You’d modify the above command and add “/Volumes//usr/bin/” to the beginning of the statement, where is the name of your hard drive. Thankfully, your Mac’s normal hard drive has this, and it will work even if it’s in read-only mode. You’ll have to point to a different volume that contains it. Zipping files through the Terminal can be helpful, especially if SSH is enabled on a remote Mac, because you can log in and zip files remotely. Unfortunately Recover Mode is a little different because the ‘du’ command isn’t included in the skeleton system you’re running. du will take them all.įor anyone doing this from the Terminal of a normally-booted Mac, this will work exactly as you see above. * – this is the filename target, and the asterisk means “everything that doesn’t start with a period.” You could specify a single directory here or a list, or individual files.Because we’re using two switches, s and h, we can combine them together with ‘ -sh‘ -h – this switch tells ‘du’ to output the sizes in ‘human-readable’ format.-s – this switch tells ‘du’ to show you one line per filename specified.So you understand what you just typed (or are about to type):
#Mac os zip switches terminal archive
Both Archive Utility and the zip command line utility discard ACLs.By issuing ‘du -sh *’ in the Terminal I can see the sizes of all my files and folders xattr also includes resource forks and file flags, because even though they are not actually stored as extended attributes, they can be accessed through the extended attributes interface. Normally you can just discard the OS X-specific metadata, but to see what metadata files contain, you can use xattr -l. The zip command line utility discards metadata such as extended attributes, file flags, and resource forks, which also means that metadata such as tags is lost, and that aliases stop working, because the information in an alias file is stored in a resource fork. _ that are used to store OS X-specific metadata. The _MACOSX directory contains AppleDouble files whose filename starts with. The top level file of a zip archive with multiple files should usually be a single directory, because if it is not, some unarchiving utilites (like unzip and 7z, but not Archive Utility, The Unarchiver, unar, or dtrx) do not create a containing directory for the files when the archive is extracted, which often makes the files difficult to find, and if multiple archives like that are extracted at the same time, it can be difficult to tell which files belong to which archive.Īrchive Utility only creates a _MACOSX directory when you create an archive where at least one file contains metadata such as extended attributes, file flags, or a resource fork.
DS_Store files inside directories but -x \*.DS_Store does. $ unzip -l a\ 2.zip # I created `a 2.zip` from Finder before this In the output below, a.zip which I created with the zip command line utility does not contain a _MACOSX directory, but a 2.zip which I created from Finder does.
For more information to zip command in the terminal app.
#Mac os zip switches terminal zip file
The zip command line utility never creates a _MACOSX directory, so you can just run a command like this: zip directory.zip -x \*.DS_Store -r directory I found the easier way to make an encrypted zip file with the terminal app on mac (mac os) just from the files of your folder.
