Adding Color using More

Daily Stupid Question:

When I use a cat with a grep I can see "blind SQL injection vulnerablity" highlighted as red and is easily readable

Code:

cat file |grep -i 'blind\ SQL\ injection\ vulnerability'

When I add a more to view the results page at a time, the color is taken away and is very hard to read.

Code:

cat file |grep -i 'blind\ SQL\ injection\ vulnerability'|more

How can I add the color when using more to view stuff page by page?

I don't know if it can be done with more. It can be done using less instead of more.

Here's a link to a short article on how to do it. The .bashrc alias offered in the Comments section works best for me.

Many thanks for the reply, Acutally you can specify the

Code:

--colors=always

using grep and it will force colors to always be "on". This was suggested to me by another forum which resolved the issue. So I added alias grep='grep --color=always' to my .bashrc, sourced it.

worked like a charm:

Code:

cat file |grep -i 'blind\ SQL\ injection\ vulnerability'|more
