        "content": "Yes \u2014 `mbsync` (from the isync project) provides several ways to make its status output much more descriptive and easier to understand. Below are tips and techniques to improve what you see while it syncs, along with explanations of what the different pieces mean.  \n\n---\n\n## Enabling More Informative Output\n\n### 1. `--verbose` (`-V`)\nUse the `-V` (or `--verbose`) flag to get more output about what\u2019s happening under the hood. According to the official documentation, this enables basic progress messages and notices. ([isync.sourceforge.io](https://isync.sourceforge.io/mbsync.html?utm_source=openai))\n\n### 2. `--debug[category]`\nTo get even more detail, especially for debugging, `mbsync` supports a `--debug` flag with optional categories. The categories let you focus on the kind of information you're interested in. Some of them:\n\n- `driver` / `driver-all`: Metadata or full message operations depending on the suffix.  \n- `maildir`: Local file store operations.  \n- `main`: General control flow / high-level steps.  \n- `net` / `net-all`: IMAP/SMTP & network-level traffic. Either just commands or commands + payloads.  \n- `sync`: Information about which messages are being added, flagged, expunged, etc. ([isync.sourceforge.io](https://isync.sourceforge.io/mbsync.html?utm_source=openai))\n\nYou can combine categories, e.g. `--debug=net-all,maildir` or even use `--debug-all`. Note: enabling `net-all` can produce very large/loggy output since it includes raw message data. ([isync.sourceforge.io](https://isync.sourceforge.io/mbsync.html?utm_source=openai))\n\n### 3. Dry-Run Mode (`--dry-run` / `-y`)\nPairing `--verbose` or `--debug` with `--dry-run` (or `-y`) lets you see what **would** happen without making any changes. Useful to preview behavior during big syncs. ([isync.sourceforge.io](https://isync.sourceforge.io/mbsync.html?utm_source=openai))\n\n---\n\n## What the Output Means\n\nIf you run with `verbose` or `debug` you'll see the status line that looks something like:\n\n```\nC: 1/2  B: 3/4  F: +13/13 *23/42 #0/0 -0/0 N: +0/7 *0/0 #0/0 -0/0\n```\n\nHere\u2019s what the parts mean:\n\n- `C:` \u2014 cumulative / which **Channels** are being processed.  \n- `B:` \u2014 how many **Boxes** (mailboxes/folders) have been opened vs total in the sync configuration.  \n- Next are two groups: **Far side** (the remote, IMAP side) and **Near side** (the local Maildir). Each has counts for:\n  - `+` new messages (added)\n  - `*` flags that were updated\n  - `#` trashed messages\n  - `-` expunged messages  ([isync.sourceforge.io](https://isync.sourceforge.io/mbsync.html?utm_source=openai))\n\nThe prefix part (e.g. `1/2` for `C:` or `3/4` for `B:`) is showing your progress in terms of how many channels/boxes you've done out of total. These counts always grow over time \u2014 mbsync does not know beforehand how many changes will happen, so it updates them as it processes. ([isync.sourceforge.io](https://isync.sourceforge.io/mbsync.html?utm_source=openai))\n\n---\n\n## Putting It All Together: Example Use\n\nHere\u2019s how you might call `mbsync` if you want really detailed output but only want to simulate what will happen:\n\n```\nmbsync -V --debug=net-all,main,sync --dry-run <channel-or-group-name>\n```\n\n- `-V`: verbose mode  \n- `--debug=net-all,main,sync`: show detailed network (even payload), core logic, and synchronization decisions  \n- `--dry-run`: no actual changes  \n\n---\n\n## Cautions & Tips\n\n- **Output size** \u2014 `--debug=net-all` especially will generate *a lot* of output. Often useful to redirect to a file (e.g. `> mbsync.log`) for inspection.  \n- **Sensitive content** \u2014 network debug modes may show message content or headers; don\u2019t share logs with credentials or messages exposed.  \n- **Version matters** \u2014 newer versions of isync (mbsync) have fixed bugs related to debugging, dry-run behaviors, and summarization. If you're using a very old version (e.g. < 1.5), you may want to update. ([reddit.com](https://www.reddit.com/r/commandline/comments/1d9ik8a?utm_source=openai))\n\n---\n\nIf you tell me which aspects of the current output aren\u2019t helpful (e.g. confusing counters, missing info, etc.), I can show you a custom setup or tweaks so you see *just what you want*. Want me to help set that up?"
