okay so bestie, welcome to kchashmgr, section 1 of the Kyoto Cabinet manual ✨ she's the command line interface to manage the file hash database, and honestly? she's giving utility-chic 💅

✨ NAME ✨

kchashmgr — command line interface to manage the file hash database. periodt. 🫶

💖 DESCRIPTION 💖

The command kchashmgr is a utility for test and debugging of the file hash database and its applications, no cap. Let's get the vocabulary straight first, because she uses these words everywhere:

• path specifies the path of a database file.
• key specifies the key of a record.
• value specifies the value of a record.
• file specifies the input/output file.

🌈 the subcommands, iykyk 🌈
