Example:

bashwd
/home/balamv


bash:more test.txt
hello
hello-ssl
welcome
welcome-ssl
hi
bye
bye-ssl
seeyou

I want to get all the lines which contain ssl and also the one does not contain ssl.

Output should be like this.


hello-ssl
welcome-ssl
hi
bye-ssl
seeyou


Note if a line [ex. hello] has the ssl line, then get only ssl.

How to achieve this?
