Add address at end of line in hosts file using sed

Question

I have a specific line in the hosts file that is used for my local Wordpress Multisite install, which looks like this:

127.0.0.1       localhost domain.dev s         


        

Answer 1

if this is the line 7

sed -i '.bak' "7 s/$/ ${site_addr}.domain.dev/" /etc/hosts

but you can use the pattern matching (a bit safer) with

sed -i '.bak' "/127\.0\.0\.1/ s/$/ ${site_addr}.domain.dev/" /etc/hosts

i recommand to also first check if the domain is not already in
