sed Advanced: Complex Editing

Advanced sed uses patterns. Ranges. Hold space. Complex edits.

Here's the thing: Advanced sed is powerful. But complex. Learn basics first.

Patterns​

sed '/pattern/d' file.txt

My take: Patterns match lines. Use them.

Ranges​

sed '2,5d' file.txt

My take: Ranges work on multiple lines. Use them.

Common Patterns​

Complex Substitution​

sed 's/pattern/replacement/g' file.txt

What's Next?​

Now that you understand advanced sed, let's talk about awk Basics.

Personal note: Advanced sed seemed too complex. Then I learned it gradually. Now I use it when needed. It's powerful. Learn it.
