Recursive search for a word in files under Linux

To recursively search for a word within files under Linux, you can use the grep command.

The following command searches all files in the current directory and all subdirectories for a specific word:

$ egrep -r -e "serch term"

For example, if you want to enable or disable the “last_updated” tag in your al-folio tree, you can find the configuration file “_config.yml”

mypc:~/Projects/mysite.github.io$ egrep -r -e "last_updated"
_posts/2024-07-22-linux-printer.md:last_updated: 2024-08-16 08:14:10
..
_config.yml:last_updated: true # set to true if you want to display last updated in the footer
..
