If you think you’re interested — this post is about the following:

1. How to get your current user/directory in the title of terminal (iTerm.app for this post — same applies for Terminal.app though)
2. How to make the backspace/delete keys work properly in nano/pico on local and remote servers
3. Update your current user/path in the title when you SSH into a remote machine
4. And how to setup password-less SSH, just because its on topic

.bashrc modifications

Making Terminal.app’s title update to the current user & path for both local and remote servers while letting the backspace and delete key work properly — all in one solution!

Add the following lines to both your local & remote .bashrc

# this is what updates your Terminal's title -- you can of course modify this
# but im not explaining how -- google it
export PROMPT_COMMAND='echo -ne "\\033]0;${USER}:${PWD}\\007"'

# this will make OSXs backspace & delete keys work properly
# in nano & pico
export TERM=xterm
stty erase ^H

# fancy prompt you say?
# again -- google for more info on this
export PS1="\\[\\033[0;34m\\][\\!]\[\\033[0;32m\\][\\u.\\h: \\w]\[\\033[0;32m\\]\\$\\[\\033[0m\\] "

#gives you something like:
# [0][rob.hades: ~]$ echo 'hello world!'

Now lets bind our servers for SSH so we don’t need passwords

Passwords are annoying — especially when you are using scp and rsync a lot.

Here is a very simple way to drop those passwords and have SSH do all the work.

In your terminal app (Locally)

Make your .ssh directory
$>mkdir -p ~/.ssh && cd ~/.ssh

Generate yourself some keys
~/.ssh $>ssh-keygen -t dsa -f ~/.ssh/id_dsa

Copy your public key to your remote server (Make sure the remote server has a ~/.ssh directory as well!)
~/.ssh $>scp id_dsa.pub {user}@{remoteserver}:.ssh

In the remote computer

Add that public key to your authorized_keys file for SSH
$>cd .ssh && cat id_dsa.pub >> authorized_keys2

Cleanup those files and make sure the authorized_keys file is set to the right perms.
~/.ssh $>chmod 640 authorized_keys2 && rm id_dsa.pub

That should make your life a bit more convenient
