Consider swapping out the standard “less” pager for one that has syntax highlighting.
Here’s one way to achieve this:
Back in 2012, Paul Irish tweeted a neat way to make “cat” colorized.
If you do this, and you like this, you can get a colorized less with no more work than a two line shell function.
If you’re looking for another way to get syntax highlighting with less, there’s something called lesspipe, but I haven’t looked into it yet.
So far I’m happy with cless.
