added script to quickly create new posts

newpost.sh

+#!/bin/sh
+if [ $# -lt 1 ]
+then
+	echo "usage: $0 title" >&2
+	exit 1
+fi
+
+FNAME=posts/$(echo "$@" | sed 's/[[:space:]]+/_/g' | tr '[:upper:]' '[:lower:]').md
+
+if [ -f "$FNAME" ]
+then
+	echo "post (\"$FNAME\") already exists" >&2
+	exit 1
+fi
+
+cat > "$FNAME" <<EOF
+title: $@
+date: $(date +"%Y-%m-%d %H:%M")
+author: $(getent passwd "$USER" | cut -d: -f5 | cut -d, -f1)
+tags: news
