adding text to hosts file

[dobyrne]

I want to be able to automate in a scripting process on how to add a server name to the hosts file in the folder etc.

for example 10.2.2.2 esxserver004.company.com.au esxserver004

I want to add esxserver004 to the end of the line. any ideas?

perl -p -i -e 's/10.2.2.2 esxserver004.company.com.au/10.2.2.2 esxserver004.company.com.au esxserver004' /etc/hosts

--Matt

hi,

mv /etc/hosts /tmp/hosts

cat /tmp/hosts | sed 's/\(.esxserver004.$\)/\1 esxserver004/ig' > /etc/hosts

hth,

Reinhard

If you just want to append a new entry, with the items tab seperated, the easiest option would be to use echo.

cp /etc/hosts /etc/hosts.backup

grep -v "esxserver004.company.com.au" /etc/hosts.backup > /etc/hosts

echo -e "10.2.2.2\tesxserver004.company.com.au\tesxserver004" >> /etc/hosts

HI Matt,

I tried the command and got substitution replacement not terminated at -e line 1. not sure what that mean?? I changed the line to.

perl -p -i -e 's/10.2.70.148 esxbnevh004.mbf.com.au/10.2.70.148 esxbnevh004.mbf.com.au esxbnevh004' /etc/hosts

sorry, that should have an extra / at the end:

perl -p -i -e 's/10.2.70.148 esxbnevh004.mbf.com.au/10.2.70.148 esxbnevh004.mbf.com.au esxbnevh004/' /etc/hosts

I tried it though wan to add the line at the entry at the end of the line instead of the appending to anther line. any ideas?

Damon

10.2.70.154 esxbnevh004.mbf.com.au esxbnevh004 (this at the end of the line)

echo -e "10.2.70.154\tesxbnevh004.mbf.com.au\tesxbnevh004" >> /etc/hosts

Hi,

grep -v is a inverted grep, it prints all the lines NOT containing the pattern and then

echo add the whole line.

or try as i posted the cat file | sed .....

bye,

Reinhard
