I should start with the observation that I hate using my mouse.
Yet, that was exactly what I was about to do today to unzip a file. The reason was simple, I didn’t (yet) know how to unzip files from the command line.
So, I learned - and it turns out it’s pretty simple.
MacOS comes with an
unzip program pre-installed, but if you don’t have one, this would be the first step.
For example, with Homebrew, you could
brew install unzip. This, it turns out, is how I found out MacOs came with its own.
Once, I installed
unzip, I received this message in the logs:
unzip is keg-only, which means it was not symlinked into /usr/local, because macOS already provides this software and installing another version in parallel can cause all kinds of trouble. If you need to have unzip first in your PATH run: echo 'export PATH="/usr/local/opt/unzip/bin:$PATH"' >> ~/.zshrc
Okay, fair enough. How do I use
Pulling up the manual page, I could see the different options and put together the case I needed.
The key part for me was that the .zip file was in my Downloads and I wanted to unzip directly to a specific directory.
For this, use the
$ unzip --man UnZip 6.00 of 20 April 2009, by Info-ZIP. Maintained by C. Spieler. Send bug reports using http://www.info-zip.org/zip-bug.html; see README for details. Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir] Default action is to extract files in list, except those in xlist, to exdir; file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage). -p extract files to pipe, no messages -l list files (short format) -f freshen existing files, create none -t test compressed archive data -u update files, create if necessary -z display archive comment only -v list verbosely/show version info -T timestamp archive to latest -x exclude files that follow (in xlist) -d extract files into exdir modifiers: -n never overwrite existing files -q quiet mode (-qq => quieter) -o overwrite files WITHOUT prompting -a auto-convert any text files -j junk paths (do not make directories) -aa treat ALL files as text -C match filenames case-insensitively -L make (some) names lowercase -X restore UID/GID info -V retain VMS version numbers -K keep setuid/setgid/tacky permissions -M pipe through "more" pager See "unzip -hh" or unzip.txt for more help. Examples: unzip data1 -x joe => extract all files except joe from zipfile data1.zip unzip -p foo | more => send contents of foo.zip via pipe into program more unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer
$ unzip file -d destination_dir
You should be greeted by a log of contents unzipping.
$ unzip ~/Downloads/js-recent-parts.zip -d .

You can then verify that all of the contents are where you expect, with
$ ls -lah total 0 drwxr-xr-x 8 stephen staff 256B May 22 08:18 . drwxr-xr-x 8 stephen staff 256B May 22 08:12 .. drwxrwxr-x@ 3 stephen staff 96B Mar 9 14:20 __MACOSX drwxr-xr-x@ 4 stephen staff 128B Mar 9 06:53 async-await drwxr-xr-x@ 4 stephen staff 128B Mar 9 06:53 destructuring drwxr-xr-x@ 4 stephen staff 128B Mar 9 06:53 iterators-generators drwxr-xr-x@ 4 stephen staff 128B Mar 9 06:54 regex drwxr-xr-x@ 4 stephen staff 128B Mar 9 06:54 template-strings
Voila - that’s it! Now you can unzip files directly from the command line.
