Remove User and Hostname in Terminal Prompt MAC

For Linux and Mac the default Terminal or ITerm2 terminal the default prompt shows the hostname, current directory etc.
Terminals shows the primary prompt PS1 when it is ready to read a command, and the secondary prompt PS2 when it needs more input to complete a command. These prompt strings can be customized by inserting a number of backslash-escaped special characters some of them are as follows:

 
\d : the date in “Weekday Month Date” format (e.g., “Tue May 26”)

\h : the hostname up to the first ‘.’

\H : the hostname

\n : newline

\r : carriage return

\t : the current time in 24-hour HH:MM:SS format

\V : the release of bash, version + patch level (e.g., 2.00.0)

\w : the current working directory, with $HOME abbreviated with a tilde

\W : the basename of the current working directory, with $HOME abbreviated with a tilde

\! : the history number of this command

\# : the command number of this command

\\ : a backslash

Good thing is that it is configurable.  To change it temporarily do the following in the terminal

$PS1="\W"$
Now the Terminal shows something like follows.






To change the behaviour we need to update the .bash or .bash_profile file as per the bash configuration.


And then save the changes and do source ~/.bashrc
Now open a new Terminal and it should reflect the changes.
