✨ CVT_CYRUSDB(8) ✨

okay bestie so this is cvt_cyrusdb, part of the Cyrus IMAP manual (section 8, system admin girlies rise up 💅). She's a lil command-line baddie whose whole job is converting a database file between cyrus database formats. that's it, that's the vibe. 🦋

🌸 NAME 🌸

cvt_cyrusdb — Cyrus IMAP documentation

literally just: convert a database file between cyrus database formats. no cap. ✨

💖 SYNOPSIS 💖

cvt_cyrusdb [ -C config-file ] old-file old-fileformat new-file new-file-format

🎀 DESCRIPTION 🎀

okay so cvt_cyrusdb is the glow-up machine for your cyrusdb files — it converts a cyrusdb file between different database backends. it's giving transformer but make it databases. 🔥

lowkey important: do NOT try to use the same file for input and output. that's a one-way ticket to chaos and we are not doing that today. 🙈

and if you run it with no options at all? she'll just be cute and list all the available database backends for you. free info, periodt. 💅

cvt_cyrusdb reads its configuration options out of the imapd.conf(5) file, unless you tell it otherwise with -C. iykyk.

NOTE: the file locations are NOT read out of the configuration file, bestie — you have to hand them over on the command line yourself. no autofill, we do it manually here. 😭

✨ OPTIONS ✨

  • -C config-file — use the specific configuration file config-file instead of the default imapd.conf(5). simple as that. 🫶

🌈 EXAMPLES 🌈

okay examples time, this is the fun part:
