Bash shell prompt is displaying odd

Your .bashrc profile is deleted some how. There would have been a recent change or event happened on your server, you can investigate it. Or a simple fix have it copied from a server where it exists to this server or manually create it.

If you login to your server, run the below commands, that should list your .bashrc file. If it doesn't exist you are required to create it.

Let me reproduce your scenario.

ltm:Active:Standalone] ~  ls -la .bashrc
-rw------- 1 user user 124 Feb  8 09:07 .bashrc

ltm:Active:Standalone] ~  cat .bashrc
 .bashrc

 User specific aliases and functions

 Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

:ltm:Active:Standalone] ~  rm .bashrc
rm: remove regular file `.bashrc'? y

After I delete the .bashrc file, When I start a fresh session, see how the shell looks.

bash-3.2
bash-3.2
bash-3.2
bash-3.2 vi .bashrc
bash-3.2

Paste the below in this file,

  .bashrc

 User specific aliases and functions

 Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

After creating you should see the files like below.

bash-3.2 ls -la
total 886
drwx------  3 user user   3072 Mar 30 02:00 .
drwxr-xr-x 27 user user   1024 Mar 12 08:00 ..
-rw-------  1 user user  53478 Mar 29 14:34 .bash_history
-rw-r--r--  1 user user     24 Jan 15  2016 .bash_logout
-rw-r--r--  1 user user    598 Mar  5  2012 .bash_profile
-rw-r--r--  1 user user    132 Mar 30 02:00 .bashrc

Now its completed fixed.

:Active:Standalone] ~ 

Note: the changes will not reflect unless a fresh session is opened.
