Modify line into my file with bash script

Question

I'm looking for modify a line in my apache2.conf file thanks to bash script. It's the first time I'm using bash script and I need help.

In my apache2.conf file, I have :

DocumentRoot /var/www/html/

And I would like to change this by :

DocumentRoot /var/www/html/erp/htdocs/

I have to write something like this into my bash script ?

sed -i 's/"old word"/"new word"/g' apache2.conf

So :

sed -i 's/DocumentRoot /var/www/html//DocumentRoot /var/www/html/erp/htdocs//g' apache2.conf

Thank you for your help !

EDIT :

#Apache2

cd /etc/apache2/sites-available/
sudo sed -i 's,/var/www/html/,/var/www/html/erp/htdocs/,g'  000-default.conf
echo -e "\033[31m Modification chemin accès dolibarr : ok"

It's not a duplicate because I didn't know which kind of command I should use in order to replace text in file with bash script.. — Essex, Nov 27 '17 at 10:11

For convenience concerns, you ca. use a different delimiter ,:

sed -i 's,/var/www/html/,/var/www/html/erp/htdocs/,g' apache2.conf

You have to escape all slashes if you use it as the delimiter:

sed -i 's/DocumentRoot \/var\/www\/html\//DocumentRoot \/var\/www\/html\/erp\/htdocs\//g' apache2.conf

Thanks to your answer ! I will try it ;) – Essex Nov 27 '17 at 09:39
Your second command doesn't seem to work. My file was not modified. – Essex Nov 27 '17 at 11:19
@Deadpool Try the first one. That's my original proposal. – iBug Nov 27 '17 at 11:37
I tried too and it doesn't work, I update my question with my command based from yours – Essex Nov 27 '17 at 11:39
@Deadpool `sudo` doesn't work well in scripts. You'd better `sudo` the whole script. – iBug Nov 27 '17 at 11:41
Ok it works because I added `/` and I shouldn't. Thank you very much ! – Essex Nov 27 '17 at 11:44
