This will output a list of all emails in a specific file or in a folder.

grep_emails_in_files.md

File

Find in a single file:

grep -E -o "\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,6}\b" someFile.txt

Folder

When checking in folders, the output will list the matches as filename:email for every match in a file.

The option --exclude-dir requires just the name of the folder to exclude, not the whole file path.

Find all in a folder:

grep -E -o -r "\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,6}\b" wwwroot/ 

File all in a folder, excluding certain folders:

grep -E -o -r --exclude-dir=folder1 --exclude-dir=folder2 "\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,6}\b" wwwroot/
