+Make the template executable:
 ```
 chmod +x someTpl.shtpl
-WHO=Doctor someTpl.shtpl

 ```
 
+In case of many variable you can write 1 var on each line, but for bash to understand you have to escape the newlines and keep 1 space before:
+
+```
+VAR1=foo \
+VAR2=bar \
+VAR3=baz \
+VAR4=aze \
+./someTpl.shtpl
+```
+
+To save the result simply redirect to sdtout to a file:
+```
+WHO=Doctor ./someTpl.shtpl > doctorGreetings.txt
+```
