Lesson: Advanced File Operations

Step 1: Find Files

Find files by name:
```
find . -name "*.txt"
```
Find files by size:
```
find . -size +1M
```
Find files modified recently:
```
find . -mtime -7
```

Step 2: Search File Contents

Search for text in files:
```
grep "search term" *.txt
```
Search recursively:
```
grep -r "search term" .
```
Show line numbers:
```
grep -n "search term" file.txt
```

Step 3: Archive Files

Create a tar archive:
```
tar -czf archive.tar.gz thesis/
```
Extract an archive:
```
tar -xzf archive.tar.gz
```
