Is it possible to print the value of the http variable?

Question

linux

Good afternoon, is it possible to somehow display the value of the DocumetRoot variable from httpdb File : /etc/httpd/conf/httpd.conf
If I do grep on the file, it comes out

# cat /etc/httpd/conf/httpd.conf | grep DocumentRoot
# DocumentRoot: The directory out of which you will serve your
DocumentRoot "/var/www/html"
    # access content that does not live under the DocumentRoot

And I want exactly /var/www/htmlwhat to assign to a variable later

Answer 1

cat 111.txt | grep ^DocumentRoot |  egrep -o '/.+[^"]'

conclusion

/var/www/html

Now it’s better
^- the beginning of the line,
respectively, will only be due to the fact that the root document begins immediately and not in the content
, and then we do grep again with only
, and then what starts with a slash but not quotes, actually this is our url -o
