10I often use `grep` to search for todo's in my code and other people's code and
11then pipe them in `less` and I missed having colors that grep outputs in `less`.
12
13- Grep's `--color=always` use markers to highlight the matching strings.
14- Less's `-R` option outputs "raw" control characters.
15
16You could use `alias grep='grep --color=always'` and `alias less='less -R'` or
17create todo function in your `.bashrc` that accepts first argument as search
18string.
19
20```sh
21# This is where the magic happens.
22grep --color=always -rni "TODO:" | less -R
23```
