Linux Find File Summary

Locate: Non-real-time lookup, the lookup process is based on the system-wide file database, the search method is not accurate.

The default system writes to the database periodically.

Pros: Find Fast.

If you do not have a database, you can create it manually, UpdateDB, but the command will take a long time to process.

Find: Real-time, accurate, traversal of all files in the specified directory to complete the lookup, the lookup speed is slow.
