Grep to extract text example

Grep command

grep -no 'name="[^ ]*"' file.html > results.txt

In this line:

    The n option will print the lines that matched the pattern. Simply for informative reasons, at first glance.     Remove if you don't want it.
    The o option prints only the matched text, not the entire line itself.
    file.html is the path to your file.
    the P option is for look arounds.

Also if you want the results saved to a file, you can pipe them by appending > results.txt:

grep -Po 'name="[^"]*"' file.html > results.txt

As below sample file results.txt will be 

Koman
Test
Monday
Tuesday
Wednesday

Sample file

name="Koman was here"
name="Test was here"
name="Monday is here"
name="Tuesday is tomorrow"
name="Wednesday is the middle of the week"
