     **- What I did**
     Added fix

     **- How I did it**
     Added code to remove last few extra characters from string

     **- How to verify it**
    Steps to reproduce:
    1. Change the naming mode to alias instead of port names
        admin@sonic-svk169-dut:~$ config interface_naming_mode
    2. Update config_db.json for port section to change alias t
    3. Reload and run following command

     **- New command output

     With shorter alias names:
    admin@sonic-svk169-dut:~$ show interfaces  counters
    IFACE    STATE    RX_OK    RX_BPS    RX_UTIL    RX_ERR    R
    -------  -------  -------  --------  ---------  --------  -
      P0        X        0       N/A        N/A         0
     P4        X        0       N/A        N/A         0
