Common Patterns

Adding Note with Full Content

For longer notes, create a temp file and import:

# Write content to temp file first, then copy to nb
cp /tmp/note.md ~/.nb/<notebook>/
cd ~/.nb/<notebook> && git add . && git commit -m "Add note"
nb <notebook>: index rebuild

Searching Across All

# Search everything
nb search "term" --all

# Search by type
nb search "term" --type bookmark
nb search "term" --type todo

Data Location

Notes are stored in ~/.nb/<notebook>/ as markdown files with Git versioning.

~/.nb/
├── notebook-name-1/ # Your first notebook
├── notebook-name-2/ # Your second notebook
└── ...

Tips

1. Use nb <notebook>: prefix to work with specific notebooks
2. IDs are numbers shown in nb list
3. Titles can be used instead of IDs (quoted if spaces)
4. All changes are automatically Git-committed
5. Use nb sync to push/pull from remote repos
