| 10 | I often use `grep` to search for todo's in my code and other people's code and | ||
| 11 | then 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 | |||
| 16 | You could use `alias grep='grep --color=always'` and `alias less='less -R'` or | ||
| 17 | create todo function in your `.bashrc` that accepts first argument as search | ||
| 18 | string. | ||
| 19 | |||
| 20 | ```sh | ||
| 21 | # This is where the magic happens. | ||
| 22 | grep --color=always -rni "TODO:" | less -R | ||
| 23 | ``` | ||
