Tracking Down zsh Alias Plugin Sources

When hunting for the origin of mysteriously defined by unknown plugin zsh aliases:

zsh -xv 2>&1 | grep "alias_name"

This works by:

1. Starting zsh with -x (trace) and -v (verbose) flags
2. Redirecting both stdout and stderr (2>&1) to capture all output
3. Filtering with grep to find when your alias is defined

For a more targeted approach with less output:

zsh -xv 2>&1 | grep -A 3 "source.*plugin" | grep "alias_name"

This helps identify which plugin file is sourcing your alias.
