Question

I want to accomplish the equivalent of the following pseudo-code in bash (both a and b are inputs to my script) :

String a = "some long string";
String b = "ri";
print (a.substring(a.firstIndexOf(b), a.length()); //prints 'ring'

How can I do this in shell script?

Answer 1

You can do:

$ a="some long string"
$ b="ri"
$ echo $a | grep -o "$b.*"
ring
