Partial find and replace with regex

example.sh

# In most text editors, there is an option to find a string using regex.
# But what if you'd like to replace a specific sentence in the expression?
# For example, let's say there are following strings in different files:
#
# NewGeneratorForService(t, "apigatewayv2")
# NewGeneratorForService(t, "rds")
#
# And you'd dike to add a new argument to all these calls and make them like following:
#
# NewGeneratorForService(t, "apigatewayv2", ackgenconfig.DefaultConfig)
# NewGeneratorForService(t, "rds", ackgenconfig.DefaultConfig)
#
# You need to find occurences with regex: NewGeneratorForService\(t, "(.*)", ackgenconfig.DefaultConfig\)
# Notice that (.*), the paranthesis makes it a "group". In the replace box, you can address the groups by index.
#
# If you write the following in replace box, then you'll be able to replace all occurences automatically!
#
# NewGeneratorForService\(t, "$1", ackgenconfig.DefaultConfig\)
