🐧 Quick Linux tip:

Got log files compressed as .gz? You don’t need to extract them to read or search through the content.

Use the 'z' tools directly:

• zcat - view the file
• zless - scroll through it
• zgrep - search inside it
• zegrep - search with extended regex
• zfgrep - search for fixed strings
• zcmp/zdiff - compare files

These commands let you inspect compressed logs without unpacking them first, perfect for quick troubleshooting sessions.

🐧 Containers vs. Virtual Machines

🐧 Quick Linux tip:

When you need to create several directories at once, you don’t have to do it one by one.

The mkdir command supports brace expansion, letting you create multiple nested directories in a single go.

$ mkdir -p ~/scripts/{site-01,site-02}/{backup,monitoring,network}

This instantly creates folders for two sites, each with its own backup, monitoring, and network directories.

A neat way to save time and keep your directory structure organized.
