# Unity theme bundled plugin monitor
|
|
|
|
Use this script to detect new releases of the WPBakery and Revolution Slider
|
|
archives bundled by the Unity theme. This is an operations script, not an MU
|
|
plugin; do not place it in `wp-content/mu-plugins/`.
|
|
|
|
## Instructions
|
|
|
|
1. Save the snippet as `unity-plugin-update.sh` outside the public web root.
|
|
2. Make the script executable.
|
|
3. Create the initial `external-plugin-update.log` baseline.
|
|
4. Run the script without arguments from a scheduled job. It exits with the
|
|
status returned by `diff` and prints any changed HTTP metadata.
|
|
5. After reviewing and deploying an update, refresh the baseline.
|
|
|
|
```bash
|
|
chmod 0755 unity-plugin-update.sh
|
|
./unity-plugin-update.sh --update
|
|
./unity-plugin-update.sh
|
|
```
|
|
|
|
## Script
|
|
|
|
```bash
|
|
#!/usr/bin/env bash
|
|
|
|
set -eu
|
|
|
|
SCRIPT_DIR="$(CDPATH='' cd -- "$(dirname -- "$0")" && pwd)"
|
|
CURRENT="${SCRIPT_DIR}/external-plugin-update.log"
|
|
REMOTE="$(mktemp)"
|
|
|
|
trap 'rm -f "${REMOTE}"' EXIT
|
|
|
|
EXTERNAL_PLUGINS=(
|
|
"https://source.wpopal.com/plugins/new/js_composer.zip"
|
|
"https://source.wpopal.com/plugins/new/revslider.zip"
|
|
)
|
|
|
|
for PLUGIN in "${EXTERNAL_PLUGINS[@]}"; do
|
|
curl -L -sI "${PLUGIN}" \
|
|
| sed -n '/^last-modified:/Ip'
|
|
done > "${REMOTE}"
|
|
|
|
if [ "${1:-}" = "--update" ]; then
|
|
cp "${REMOTE}" "${CURRENT}"
|
|
exit 0
|
|
fi
|
|
|
|
if [ ! -f "${CURRENT}" ]; then
|
|
echo "Baseline is missing. Run $0 --update first." >&2
|
|
exit 2
|
|
fi
|
|
|
|
diff -u "${CURRENT}" "${REMOTE}"
|
|
```
