# Show a unified diff between an installed plugin and a clean copy from
|
|
# wordpress.org. Useful for investigating failed `wp plugin verify-checksums`
|
|
# results to see exactly what changed.
|
|
#
|
|
# Usage:
|
|
# captaincore ssh <site> --script=plugin-diff --plugin=<slug>
|
|
# captaincore ssh <site> --script=plugin-diff --plugin=<slug> --version=1.2.3
|
|
# captaincore ssh <site> --script=plugin-diff --plugin=<slug> --stat
|
|
# captaincore ssh <site> --script=plugin-diff --plugin=<slug> --keep
|
|
#
|
|
# Flags:
|
|
# --plugin=<slug> Plugin slug to diff (required)
|
|
# --version=<ver> Override detected version
|
|
# --stat Show diffstat only (no full diff)
|
|
# --keep Don't remove the downloaded clean copy after running
|
