How to shorten the bash shell prompt

So sometimes it happens that you are working on command terminal and you navigate inside a directory then again in inner directory and so on until half of the screen width is filled with prompt string. Example below....

rana@Brahma: dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8 $ ls 

Now I want to display just the last directory in terminal prompt string so that I am left with enough width space to execute length commands.

For this We need to change the prompt string from .bashrc file. Below are the steps -

1. Go to your home directory.
2. Open .bashrc file.
3. Search for string 'PS1'. To search quick open the file in vi and type /PS1 and hit enter.
4. now you will find below code. (or similar to it) [ I am working on Ubuntu 16.04]

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

5. Replace the 'w' (highlighted in blue color) with capital W. So your new code will be.

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]: \[\033[01;34m\]\W\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

6. Restart the terminal and navigate inside any directory. You will see just the last directory in teminal prompt.

rana@Brahma: dir8$

Unix is very simple. It just needs a genius to understand its simplicity.

This is the famous quote by father of Unix and C - Dennis Ritchie

Unix is Fun

Sharing files in Linux.

Wanna Share some file with your friend ? Here are three methods.

1. The traditional way. Transfer files to Pen Drive and then your friend copy it to their system. This is the best way to share if both system are not in same network.

Cons - 

• File is copied 2 times.
• What if file size is more than size of pen drive.

2. Install apache 2.
