Question

I’m trying to replace a word at a specific position of a line

For example, given:

INSERT INTO address (city_id,city) VALUES (1,'Monrovia');
INSERT INTO address (city_id,city) VALUES (2,'Brunswick');
INSERT INTO address (city_id,city) VALUES (3,'Phenix City');

I want to replace all different the cities with ‘Detroit’, resulting in:

INSERT INTO address (city_id,city) VALUES (1,'Detroit');
INSERT INTO address (city_id,city) VALUES (2,'Detroit');
INSERT INTO address (city_id,city) VALUES (3,'Detroit');

Please, How can i do that in sed, awk, or vim?

Thank you.

Answer 1

Easiest: Keep the script, append

UPDATE address SET city ='Detroit'

In vim:

:g/^INSERT INTO address/normal f;F'ci'Detroit

In sed:

sed "s/\(VALUES (.*,\)'.*\?'/\1'Detroit'/g"
