What is File Compression?
File compression is the process of reducing the size of one or more files to make them occupy less storage space. It’s like packing your belongings efficiently before a long journey. In Linux, one of the most common compression formats is .gz, which uses the gzip utility.
Why Use .gz Compression?
- Space Savings: Compressed files take up significantly less space on your hard drive, which can be especially important for servers or devices with limited storage.
- Faster Transfers: Smaller files are quicker to upload, download, or transfer, saving you time and bandwidth.
- Organized Storage: Compression helps you keep your files organized, making it easier to manage your data efficiently.
Getting Started
Before we jump into the compression process, ensure you have Linux terminal access. Open a terminal and follow along with the following steps.
Step 1: Navigate to the Directory
To compress a file, you need to be in the same directory as the file you want to compress. Use the cd command to navigate to the relevant directory.
Step 2: Compressing a Single File
To compress a single file, use the gzip command followed by the filename. For example:
gzip filename.txt
Step 3: Decompressing a .gz File
To decompress a .gz file, use the gunzip command. For example:
gunzip filename.txt.gz
