Osx Zip Command Line

One alternative is to create split zip files using the zip tool provided with OS X. As described in man zip, the resulting files are not just one big zip file that has been split into pieces, and thus they cannot gracefully be concatenated back together as described in another hint, so this differs from simply using the split command.

How to Zip and Unzip Files Command Line Terminal on a Mac OS X Yosemite Simple Zip Command:zip -r archivename.zip foldertocompressUnzipping from the comma.
Zip archive.zip file.txt Another simple way to create an archive from the command line is to use the Terminal’s drag & drop support, type out ‘zip’ as usual but then drop in the file (s) to compress into the Terminal window. Unzipping from the command line is also very simple, with the easy ‘unzip’ command.
You need only run a simple command to create the split archive, but it’s important that you understand its syntax in order to customize it for your needs. The command is as follows: zip -r -s MaximumSize ArchiveName.zip FolderName/ As the name suggests, the MaximumSize part is the maximum possible size each split file should be.

The command line—that hidden world of code behind your Mac’s pretty face—sometimes offers a quicker way to do everyday tasks, plus it’s just a cool way to establish your tech cred. You’ve learned how to navigate files and folders as well as delete files and folders with the command line and get help when you need it from man pages. Here, I’ll show you how to copy and move files, common operations that often come in handy. I’ll also show you how to create directories (that’s Unix-speak for folders), so you can move files to new places.

Why bother with the command line?

It’s certainly easy to copy and move files in the Finder, but there are a number of reasons why you might want to do this from the command line instead:

You can copy or move files from one location to another without opening windows in the Finder.
You can copy or move files that are hidden in the Finder. These files, which can contain settings for certain apps or parts of the Mac, contain a dot (.) before their names, and the Finder doesn’t show them.
You can copy or move multiple files using wildcards.
You can rename a file quickly.
If you’ve lost access to the Finder because your Mac is on the blink, you might be able to use the command line to troubleshoot the problem.

The difference between copying and moving files

If you’re in the Finder, and you drag a file from, say, your Desktop to your Documents folder, or any other folder on the same disk or volume, you move the file. The file is no longer on the Desktop, and is found only in the Documents folder. However, if you drag a file from your Desktop to an external hard disk, you’ll see that the file remains in its original location; this file has been copied. Mac os recent update. (You may know that you can copy a file in the Finder, even on the same hard disk, by holding down the Option key when you drag it.)

The same is the case from the command line. There are two commands for moving and copying: mv and cp. The first does the same as dragging a file to a new location on the same hard disk; the second does what an Option-drag does, or what happens when you drag a file to a different disk or volume.

How to copy files

Copying files with the cp command is simple. First, launch Terminal (in your /Applications/Utilities folder). Then, use the following syntax to create your command:

cp source destination

For example, to copy a file named MyFile.rtf from your Desktop folder to your Documents folder, you would type in the following command in Terminal and then press Return:

cp ~/Desktop/MyFile.rtf ~/Documents

You’ll now have a file named MyFile.rtf on your Desktop, and a copy of that file in your Documents folder. Download windows parallel for mac free.

You’ll remember from “Master the command line: Navigating files and folders” that the tilde (~) symbol is a shortcut for your Home folder, which contains your Documents folder. This command takes the file at the precise path you specify as the source argument, and moves it to the directory (folder), which is the destination. Note that if there’s no file there, or if you type the name incorrectly, Terminal will give you a “No such file or directory” error.

You can also copy directories, including all the files they contain. This uses a special “flag” or “option” with the cp command: the -R or recursive flag. When you use options with commands, this additional letter—always preceded by a hyphen (-)—tells the command to do something a bit differently. The recursive option tells the cp command to copy every item in the folder: every sub-folder, every file and folder in every sub-folder, and so one, all the way down, to the new location. So you can copy a directory from your Desktop to your Documents folder like this:

cp -R ~/Desktop/MyFolder /Documents

How to move files

You’ve probably guessed that the mv command works in the same way. But there are two ways you can use the mv command. The first moves a file to a different disk or volume; remember, just as in the Finder, copying a file to a different volume won’t delete the original, whereas moving will. So you could issue this command to move a file from your Desktop to a folder on a backup disk:

You can also move directories with the mv command. The syntax is the same, and you don’t need the -R flag as you do with the cp command.:

mv ~/Desktop/MyFolder /Volumes/Backup

How to copy or move multiple files

One of the great things about the command line is the way you can use wildcards to simplify commands. For example, if you want to copy all the .rtf files (Rich Text Files) from your Desktop to your Documents folder, you can use the asterisk (*) wildcard:

cp ~/Desktop/*.rtf ~/Documents

You can use the same wildcard with the mv command to move multiple files.

How to rename files

The mv command also lets you quickly rename files. What you do is essentially move a file to the same location, but change its name. If you specify a name for its destination, the mv command changes the file’s name when it moves the file. You can change a file name like this:

mv ~/Desktop/MyFile.rtf ~/Desktop/MyFile-old.rtf

This is a valuable tool for troubleshooting; you can use this to create a backup copy of a file, such as a preference file, in case you need it again. But you can also use this renaming method simply because you want to rename a file.

You can also copy a file with cp and change its name. In this case, you need to specify not just a destination directory, but also a name for the file:

cp ~/Desktop/MyFile.rtf ~/Documents/MyFile1.rtf

How to create directories (a.k.a. folders)

Here’s one final command that may come in handy: mkdir, the make directory command. This is very useful when you need to make a bunch of folders in one fell swoop, say for a new project you’re starting. First use the cd (change directories) command to move into the directory where want to create a new directory. Once you’re there, run this command:

mkdir MyDirectory

You can use any name for the directory (for instance, “Hot Project” or “TPS Reports”), and you can make multiple directories with a single command:

mkdir MyDirectory1 MyDirectory2 MyDirectory3

With these three simple commands—mv, cp, and mkdir—you’ll be able to copy and move files, as well as create directories to hold files anywhere in your Mac’s file system. As you become proficient with these commands, you’ll see how easy they are to use.

Package and compress (archive) files.

will remove the entry foo/tom/junk, all of the files that start with foo/harry/, and all of the files that end with .o (in any
path). Note that shell pathname expansion has been inhibited with backslashes, so that zip can see the asterisks, enabling
zip to match on the contents of the zip archive instead of the contents of the current directory. (The backslashes are not
used on MSDOS-based platforms.) Can also use quotes to escape the asterisks as in

Not escaping the asterisks on a system where the shell expands wildcards could result in the asterisks being converted to a
list of files in the current directory and that list used to delete entries from the archive.
Under MSDOS, -d is case sensitive when it matches names in the zip archive. This requires that file names be entered in upper case if they were zipped by PKZIP on an MSDOS system. (We considered making this case insensitive on systems where paths were case insensitive, but it is possible the archive came from a system where case does matter and the archive could include both Bar and bar as separate files in the archive.) But see the new option -ic to ignore case in the archive.

zip is a compression and file packaging utility for Unix, VMS, MSDOS, OS/2, Windows 9x/NT/XP, Minix, Atari, Macintosh, Amiga, and Acorn RISC OS. It is analogous to a combination of the Unix commands tar(1) and compress(1) and is compatible with PKZIP (Phil Katz's ZIP for MSDOS systems).
A companion program (unzip(1L)) unpacks zip archives. The zip and unzip(1L) programs can work with archives produced by PKZIP (supporting most PKZIP features up to PKZIP version 4.6), and PKZIP and PKUNZIP can work with archives produced by zip (with some exceptions, notably streamed archives, but recent changes in the zip file standard may facilitate better compatibility). zip version 3.0 is compatible with PKZIP 2.04 and also supports the Zip64 extensions of PKZIP 4.5 which allow archives as well as files to exceed the previous 2 GB limit (4 GB in some cases). zip also now supports bzip2 compression if the bzip2 library is included when zip is compiled. Note that PKUNZIP 1.10 cannot extract files produced by PKZIP 2.04 or zip 3.0. You must use PKUN-ZIP 2.04g or unzip 5.0p1 (or later versions) to extract them.
See the EXAMPLES section at the bottom of this page for examples of some typical uses of zip.
Large Archives and Zip64. zip automatically uses the Zip64 extensions when files larger than 4 GB are added to an archive, an archive containing Zip64 entries is updated (if the resulting archive still needs Zip64), the size of the archive will exceed 4 GB, or when the number of entries in the archive will exceed about 64K. Zip64 is also used for archives streamed from standard input as the size of such archives are not known in advance, but the option -fz- can be used to force zip to create PKZIP 2 compatible archives (as long as Zip64 extensions are not needed). You must use a PKZIP 4.5 compatible unzip, such as unzip 6.0 or later, to extract files using the Zip64 extensions.
In addition, streamed archives, entries encrypted with standard encryption, or split archives created with the pause option may not be compatible with PKZIP as data descriptors are used and PKZIP at the time of this writing does not support data descriptors (but recent changes in the PKWare published zip standard now include some support for the data descriptor format zip uses).
Mac OS X. Though previous Mac versions had their own zip port, zip supports macOS as part of the Unix port and most Unix features apply. References to 'macOS' below generally refer to macOS versions older than macOS. Support for some Mac OS features in the Unix macOS port, such as resource forks, is expected in the next zip release.
For a brief help on zip and unzip, run each without specifying any parameters on the command line.

The program is useful for packaging a set of files for distribution; for archiving files; and for saving disk space by temporarily compressing unused files or directories.
The zip program puts one or more compressed files into a single zip archive, along with information about the files (name, path, date, time of last modification, protection, and check information to verify file integrity). An entire directory structure can be packed into a zip archive with a single command. Compression ratios of 2:1 to 3:1 are common for text files. zip has one compression method (deflation) and can also store files without compression. (If bzip2 support is added, zip can also compress using bzip2 compression, but such entries require a reasonably modern unzip to decompress. When bzip2 compression is selected, it replaces deflation as the default method.) zip automatically chooses the better of the two (deflation or store or, if bzip2 is selected, bzip2 or store) for each file to be compressed.

EXAMPLES

PATTERN MATCHING

This section applies only to Unix. Watch this space for details on MSDOS and VMS operation. However, the special wildcard characters * and [] below apply to at least MSDOS also.
The Unix shells (sh, csh, bash, and others) normally do filename substitution (also called 'globbing') on command arguments. Generally the special characters are:

When these characters are encountered (without being escaped with a backslash or quotes), the shell will look for files relative to the current path that match the pattern, and replace the argument with a list of the names that matched.
The zip program can do the same matching on names that are in the zip archive being modified or, in the case of the -x (exclude) or -i (include) options, on the list of files to be operated on, by using backslashes or quotes to tell the shell not to do the name expansion. In general, when zip encounters a name in the list of files to do, it first looks for the name in the file system. If it finds it, it then adds it to the list of files to do. If it does not find it, it looks for the name in the zip archive being modified (if it exists), using the pattern matching characters described above, if present. For each match, it will add that name to the list of files to be processed, unless this name matches one given with the -x option, or does not match any name given with the -i option.
The pattern matching includes the path, and so patterns like *.o match names that end in '.o', no matter what the path prefix is. Note that the backslash must precede every special character (i.e. ?*[]), or the entire argument must be enclosed in double quotes (').
In general, use backslashes or double quotes for paths that have wildcards to make zip do the pattern matching for file paths, and always for paths and strings that have spaces or wildcards for -i, -x, -R, -d, and -U and anywhere zip needs to process the wildcards.
