my approach …
The following script must be executed in the magicmirror folder and creates another script restore.sh. This result script should be saved (on my server it is under git control) and can be executed (again in the magicmirror folder) to restore the old system (or bringing the old config to a new system).
#!/bin/sh
base="$(cd "$(dirname "$0")" && pwd)"
restore="$base/restore.sh"
config="${1:-config/config.js}"
css="css/custom.css"
modules="modules"
# Tests
[ -f "$base/$config" ] || (echo "config.js does not exists" && exit 1)
[ -f "$base/$css" ] || (echo "custom.css does not exists" && exit 1)
[ -d "$base/$modules" ] || (echo "modules directory does not exists" && exit 1)
echo "#!/bin/sh" > $restore
echo "" >> $restore
echo "base=\"\$(cd \"\$(dirname \"\$0\")\" && pwd)\"" >> $restore
echo "" >> $restore
echo "mkdir -p \$base/config" >> $restore
echo "mkdir -p \$base/css" >> $restore
echo "mkdir -p \$base/modules" >> $restore
echo "" >> $restore
echo "cat > \$base/$config <<\"EOF\"" >> $restore
cat <$base/$config >> $restore
echo "EOF" >> $restore
echo "" >> $restore
echo "cat > \$base/$css <<\"EOF\"" >> $restore
cat <$base/$css >> $restore
echo "EOF" >> $restore
echo "" >> $restore
for dir in $(find "$modules" -maxdepth 1 -mindepth 1 -type d)
do
[ -f "$dir/.git/config" ] && mods="$mods $(cat $dir/.git/config | grep 'url = ' | sed 's|.*url = ||g')"
done
for repo in $mods
do
echo "cd \$base/$modules && git clone $repo" >> $restore
done
echo "" >> $restore
for repo in $mods
do
moddir="$modules/$(echo $repo | sed -r 's|.*\/(.*)|\1|g;s|.git||g')"
[ -f "$base/$moddir/package.json" ] && echo "cd \$base/$moddir && npm install" >> $restore
done
echo "Created restore script $restore"
chmod +x $restore
