tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

CRC has a daemon, which can be used to do some basic CRC operations, to start the daemon run crc daemon or with debug logging crc daemon --log-level debug In case of macOS and Windows, crc setup --enable-experimental-features will start the daemon but it'll also start the tray.

The daemon when started, listens on a Unix socket at $CRC_HOME/crc.sock, (~/.crc/crc.sock in linux and macOS) for commands/requests.. After connecting to the socket, it accepts commands as a JSON.

It understands a subset of the crc CLI commands:

CLI commands	Daemon api	Response

Git Compression of Blobs and Packfiles.

Many users of Git are curious about the lack of delta compression at the object (blob) level when commits are first written. This efficiency is saved until the pack file is written. Loose objects are written in compressed, but non-delta format at the time of each commit.

A simple run though of a commit sequence with only the smallest change to the image (in uncompressed TIFF format to amplify the observable behavior) aids the understanding of this deferred and different approach efficiency.

The command sequence:

Create the repo:

Windows

Todo:

1. Design config UI
2. Use daemon config api to modify crc configuration
3. Create a progress window and animate icon
4. Prompt user for pull secret bundle if not configured

In progress:

1. Reduce the number of UAC prompts during setup
