Scribbles for my bad memory

1. use:^ (shift + 6)

This moves the cursor to the first non-blank character of the current line.

2. _ (underscore)

This also moves the cursor to the first non-blank character on the same line the cursor is on.

By the way, the 0 command moves to the absolute start of the line, including any leading whitespace.

docker network ls
then 
docker network rm networkname

Muscle Memory Makeover

Docker just streamlined Docker Compose by integrating it as a plugin. Great news, but it means us old hats need to retrain our fingers. Here's a quick fix for your .bashrc to keep things smooth:

alias docker-compose='docker compose'

MySQL in a Flash

As a programmer and Linux admin, I juggle multiple MySQL servers with different group suffixes. Typing --defaults-group-suffix every time was a drag. This handy bash function saves the day:

m() {
    if [ $# -eq 0 ]; then
        # If no arguments provided, run mysql directly
        mysql
    elif [[ "$1" == -* ]]; then
        # If first argument starts with -, pass all arguments directly to mysql
        mysql "$@"
    else
        # Otherwise, treat first argument as suffix
        local suffix=$1
        shift
        mysql --defaults-group-suffix=$suffix "$@"
    fi
}

Now, connecting to a database is as easy as:

m specific-suffix

This keeps your workflow concise and saves you precious keystrokes. Put them into you .bashrc or .zshrc now and let our life easier!
