I recently had a need to unzip a whole bunch of zip files at work containing new client RADIUS certificates to be installed on the clients due to the depreciation of the SHA1 algorithm for security reasons by the software vendors (Microsoft and Apple in this case).
These zip files contained one useful certificate file (a .pfx containing the required certificate and the new certificate chain) per zip and a bunch of other files that are only applicable in certain situations, that I need to remove once decompressed and extracted the files from the zip archive. I consequently used a simple multiple-step process utilizing the power of the terminal prompt/command line to achieve this.
Firstly if you are needing to do this, I am assuming the files are all easily accessible and to make it easier, let’s make a directory to house all the initial zip files and put the files in there, this makes the cleanup so much easier later.
Once this is achived we can utilise the terminal prompt to make the rest of the process easier. I recommend you do this and put the files in their own directory as the following command swquice will unzip ALL zip archives files (or rather it will attempt to unzip anything with a .zip extension) in the directory, and will delete them if you do that part of the process.
Open terminal (Type Terminal into Spotlight Command + Space Bar or it is in the Application/Utilities folder)
In terminal do the following
[code language=”bash”]# go to the containing folder
#Unzip all the Files in the directory (escape “\” is used to stop wildcard expansion)
#Remove All Zip Files – To change the file types to remove change the “zip” portion of the command
rm -f *.zip[/code]
Nice and easy, the files are now extracted and the initial zips (and other files if you ran the delete command on extra extensions) are removed, leaving you just the files that you require
