You did not tell us what error you got when executing this command. I can see that you are trying to replace some value with a file path containing slashes. You need to either escape the slashes \/ of file path or use another form of sed delimiters like this:

sed -e 's|\${dir}|/home/username>|' /etc/nginx/site.conf

Please, note that this command will not change the input file. It will show the modified output to stdout. Use -i option to update the file in-place or redirect output to another file.

if i want to read from one template file, and write to other ? – Piduna Mar 30 '17 at 15:05
@Piduna: Use sed command with redirect `>` to write to another file. – Khaled Mar 30 '17 at 15:06
yes, but if i start it in a loop, where i have several usernames. i have only first username in all files – Piduna Mar 30 '17 at 15:10
