EDIT: As pointed out by @Ivanivan, we could just use this regex in a grep instead of scripting anything:
grep "^[a-z0-9!#\$%&'*+/=?^_\`{|}~-]+(\.[a-z0-9!#$%&'*+/=?^_\`{|}~-]+)*@([a-z0-9]([a-z0-9-]*[a-z0-9])?\.)+[a-z0-9]([a-z0-9-]*[a-z0-9])?\$" my_email_list.txt >> my_valid_emails.txt
A simple script can sort this for you. As commented above by @ilkkachu and @Mark Plotnick, some of those examples are perfectly valid email addresses.
email_validate.sh:
#!/bin/bash
# email regex check
email_valid="^[a-z0-9!#\$%&'*+/=?^_\`{|}~-]+(\.[a-z0-9!#$%&'*+/=?^_\`{|}~-]+)*@([a-z0-9]([a-z0-9-]*[a-z0-9])?\.)+[a-z0-9]([a-z0-9-]*[a-z0-9])?\$"
# set field separator to new lines
IFS=$'\n'
# for loop checking line against regex above
for line in $(cat my_email_list.txt); do
if [[ $line =~ $email_valid ]]; then
echo "$line is valid"
else
echo "$line is invalid"
fi
done
example output:
┌─[root@Fedora]─[~]─[03:27 pm]
└─[$]› ./email_validate.sh
89 is @msn .com is invalid
89!3@nomail.com is valid
89%@yahoo.com is valid
89%azn@yahoo.com is valid
89':s@msn.com is invalid
89'Mustang@yahoo.com is invalid
89's@msn.com is invalid
89&main@yahoo.com is valid
89+475asdjkl:jkl@aol.com is invalid
89+475asdjkl;jkl@aol.com is invalid
89+ggg@hotmail.com is valid
if you need them deleting from the file as it runs through, just add a sed '/$line/d' to the if statement. Though I would personally recommend moving valid emails to a new file instead, in case you need to refer to the old
if [[ $line =~ $email_valid ]]; then
echo "$line is valid"
echo "$line" >> my_valid_emails.txt
else
echo "$line is invalid - deleting"
fi
Which will return something like this:
┌─[root@Fedora]─[~]─[03:34 pm]
└─[$]› cat my_valid_emails.txt
89!3@nomail.com
89%@yahoo.com
89%azn@yahoo.com
89&main@yahoo.com
89+ggg@hotmail.com
