直接使用脚本或命令删除 solaris 上的主机文件条目

Question

I have requirement where I want to delete a entry from /etc/hosts file matching a particular entry

For example

I want to delete an entry like below

192.168.1.1 test001 test001.test.test.com

How can I do this either using a single line command or a script.

Answer 1

This deletes the string from your hosts file

sed -i -e "/192.168.1.1 test001 test001.test.test.com/d" filename

You might need regular expressions to catch whitespace between the words which might be blanks or tabs:

sed -i -e "/192.168.1.1.*test001.*test001.test.test.com/d" filename

Answer 2

You can try something like:

grep -v "192.168.1.1 test001 test001.test.test.com" /etc/inet/hosts >/tmp/hosts
mv /tmp/hosts /etc/inet/hosts

The file and path differ because /etc/hosts in Solaris is softlink to /etc/inet/hosts
