$ sudo ln -s /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl /usr/bin/subl

Now, you can use something like:

$ subl .

to open up current folder with SublimeText

Append the following lines to your ~/.bashrc or ~/.bash_profile or whatever your are using for dumping your bash configs.

 --- >8 --- >8 --- >8 CUT HERE ... >8 --- >8 --- >8

settitle () 

{ 

 echo -ne "\033]0;${PWD/$HOME/~}\007" 

} 

PROMPT_COMMAND=settitle

export PROMPT_COMMAND

--- >8 --- >8 --- >8 ... TO HERE >8 --- >8 --- >8

Here are the steps I did.

Let suppose our remote server (in my case, university computer) is called server.universityname.edu, your usual username is foouser, and you want to give an alias sshserv to connect to the remote server using ssh.

1. Create a local ssh key on your local computer

$ ssh-keygen -t -rsa

There are other algorithms you can use to create your ssh key. I’m using rsa for this tutorial. ssh key algorithms and secure algorithms are too broad to be covered in this tutorial.

Anyway, you should have a id_rsa.pub file inside ~/.ssh folder. Do

$ ls ~/.ssh/

and make sure you have a id_rs.pub file

2. Copy the public file to your remote server:

$ scp ~/.ssh/id_rsa.pub foouser@server.universityname.edu:.ssh/authorized_key_local

You will be prompted for password. Use your usual ssh password.

3. Log in to your remote server to manage the key:

$ ssh foouser@server.universityname.edu

Again, you will be prompted for a password.

4. Concatenate the contents of ~/.ssh/authorized_key_local to ~/.ssh/authorized_keys:

$ cat ~/.ssh/authorized_key_local >> ~/.ssh/authorized_keys

5. Remove the ~/.ssh/authorized_key_local file which is not required anymore:

$ rm ~/.ssh/authorized_key_local

6. Logout from the remote server:

$ exit

7. You are now set so that you don’t need the password every time you ssh into your remote server. Verify this by:

$ ssh foouser@server.universityname.edu

At this point, you shouldn’t be asked for any password. If you are prompted for a password, please make sure your properly followed this tutorial up to this point.

8. If you are in your remote server, exit so that you are on local computer:

$ exit

Now, let’s setup an alias.

1. Edit your ~/.ssh/config file to add the following. If the file doesn’t exist, create it first.

#The Host is the alias that you want to use

Host=myremoteserv

#The Hostname is the real hostname of the remote server

Hostname=server.universityname.edu

#The user is your username

User=foouser

2. Save the file and try:

$ ssh myremoteserv

You should be able to login to your remote server.

3. If you want to save 3 keystrokes every time you ssh using above command, you can add an alias for the whole command in your ~/.bash_profile file:

alias sshserv="ssh myremoteserv"

4. To use the alias ‘sshserv’, either restart the terminal or update your bash profile:

$ source ~/.bash_profile

5. Now, you can login to your remote server by just using:

$ sshserv

Happy ssh-ing!

So, this turned out to be pretty good and pretty productive. I needed a similar kind of script for processing my C# files that I’ve written for my NetFilterFramework. This framework basically allows you to filter a list based on some binary expressions criteria. You just have to create a string expression such off a public property of a class e.g. Name property of a Student class.

Writing this first ever Python Script was fun. I starting was very rough and edgy. I used IDLE at first to see how it goes and then ran a number of tests on some dummy files to see the results. All went fine with some minor problems. The big stumbling block was command line parsing. Although Python’s inbuilt command line parsing (using OptParse) is super awesome, the manual on their site was not that help and too verbose. So, I needed to take the help of some external sites. So was for recursively traversing a folder to read all the files. Following sites turned out to be very helpful while writing this script:

And of course stackoverflow.com is always there. Thanks to heavens for this internet thing.

Here is the my first ever Python Script in its entirety:
