Editing the Host file

[George Abraham_3]

Hello Admins,

I currently have a file with about 300 lines of the following:



erdpri.salem.gsk.com. 165.156.1.52

erdbck.salem.gsk.com. 165.156.1.53

erdvxt.salem.gsk.com. 165.156.1.54



I need to insert "IN A" (minus the double quotes) in between the

two fields can anyone help me with a script? It needs to look like

this...


erdpri.salem.gsk.com. IN A 165.156.1.52

erdbck.salem.gsk.com. IN A 165.156.1.53

erdvxt.salem.gsk.com. IN A 165.156.1.54


Thanks In advance
George

Hi George

vi /etc/hosts

:1,$ s/erdbck.salem.gsk.com/erdbck.salem.gsk.com IN A/g

hi,

try this:

# sed 's/salem.gsk.com./salem.gsk.com. IN A/' /etc/hosts > /etc/hosts.replaced

since the domain name, salem.gsk.com is the common variable to replace.

regards.

I agree with Biswajit Tripathy. But octet1 is same, using vi is possible
#vi /etc/hosts
:1,$s/165/IN A 165
vi will replace for U.
