 If you save it to `~/.bashrc`, then you can call it as any `alias` defined there.
 
+### Better to source our file in `.bashrc` rather then defining there
+
+It is better to have a separate file for wildduck related commands, and 
+`source` it in `bashrc` file, then polluting too much it.
+
+So we create a file named `~/.wildduck.commands`, and `source` it.
+Paste this at the end of `~/.bashrc` file:
+
+```
+# include .wildduck.commands if it exists
+if [ -f $HOME/.wildduck.commands ]; then
+    . $HOME/.wildduck.commands
+    echo ".wildduck.commands file has been sourced
+fi
+```
+
+Please not, that `. file` is the same as `source file`. But dot itself is 
+POSIX compatible, while `source` is bash builtin (and some other shells too), 
+but bash itself [does not make a distinction between dot and source](https://stackoverflow.com/a/20094373).
