+# generate random string from charset as first argument and length as second
+#
+# example:
+# $ rand '1-9a-f' 10
+# > 329402aa42
+#
+# defaults:
+# charset -- all printable characters and space
+# length  -- 25
+
+[ -z $1 ] && charset=' -~' || charset=$1
+[ -z $2 ] && length=25 || length=$2

+tr -cd "$charset" < /dev/urandom | fold -w "$length" | head -n 1
