Quickly navigate your filesystem from the command-line

I have been interested to the topic Data Science for a while. Today, I was looking for any book on this topic and I came across this one Data Science at the Command Line. The book is not published yet and I can read it through Safari Books Online. I then came across the writer's blog. Among many things, I found this page http://jeroenjanssens.com/2013/08/16/quickly-navigate-your-filesystem-from-the-command-line.html very very interesting. Since I found it so useful, I felt mentioning it here. All credit goes to Jereon Janssens. 

avoid strange characters for FTP password

I recently created a ftp server on Amazon created strong password (LAl)#oT!qjyQT!:@*)for a user's login.  Though I could login using that credential using FileZilla, the user was not having success. He was seeing the following error:

Status:                  Resolving address of ftp.***.com
Status:                  Connecting to *.*.*.*:21...
Status:                  Connection established, waiting for welcome message...
Response:            220 (vsFTPd 2.2.2)
Command:          AUTH TLS
Response:            530 Please login with USER and PASS.
Command:          AUTH SSL
Response:            530 Please login with USER and PASS.

Error:       Critical error: Could not connect to server

It had turned to be encoding issue. I found this good explanation here which made things clear for me. 

The lesson for is, keep ftp passwords simpler in future.
