Replace line in php file with sed from bash

Question

I try to replace some text in a file with the command sed from bash

I want to replace the line :

$app["gentle.root"] = "/home/doc/";

to

$app["gentle.root"] = "/home/exemple/";

I try :

sed -i's/$app["gentle.root"] = "/home/doc/";/$app["gentle.root"] = "/home/exemple/";' /home/martialp/Documents/default.php

But I'm getting this error

sed: -e expression n°1, caractère 7: commande inconnue: `m'

You should escape spcial symbols:

sed -i 's/\$app\[\"gentle.root\"\] = \"\/home\/doc\/\"\;/\$app\[\"gentle.root\"] = \"\/home\/exemple\/\"\;/'  /home/martialp/Documents/default.php

or you can avoid having to escape N number of / chars, by using an alternate substitute/replace field delimiter, like s@1/string@2/string' Some seds require being "notified" that you're deliberatly using an alternate delim, and you have to do s\@1/string@2/string@' Good luck to all.

Think from another way, and recommend to use other Character if the replace line has "/" in it.

sed '/gentle.root/ s#/home/doc#/home/exemple#' file
