Unzip (decompress) and extract files from a .tar.gz file

Run:

$ tar -xvzf file.tar.gz

First a reminder:

why do we end up with a .tar.gz file?

tar collects multiple files to create one single file. Then, we use gzip to compress that single .tar file into a .gz file, thus the compound .tar.gz extension.

So to reverse the process, we first need to decompress file.tar.gz using gzip, and then extract the files from the remaining file.tar.

What do the options we pass mean?

• z tells tar to decompress the file using gzip
• x extracts all files from the .tar file.
• f tells tar the path and name of the file to decompress and extract; this must be the last flag of the command, and the .tar.gz file must come right after.
• v makes tar list all the files being extracted in the terminal as the command runs

To extract into a specific folder, pass the -C option to the command followed by the name of the folder where you want tar to extract the files:

$ tar -xvzf file.tar.gz -C folder

I do self-funded research and I'm writing a book.

> What's the book about?

About technologies and agency.

Meaning, technologies can foster agency. No doubt. But I am also asking:

Can usage of technologies give us a sense of empowerment while in fact undermining our abilities?

I posted a summary of the prologue on the homepage: https://yctct.com/
