[SOLVED] Match one substring and replace another on same line

Issue

I want to change all true values to false for all lines that contain should-log substring, the input files contain other lines to but are not mentioned in this snippet:

logging.ap.should-log-headers = true
logging.ap.should-log-password = true
logging.api.should-log-headers = true
logging.httpbin.should-log-headers = true
logging.httpbin.should-log-password = true
logging.copy.should-log-headers = false
logging.copy.should-log-password = false
logging.test.should-log-headers = false
logging.test.should-log-password = false
logging.-test.should-log-password = true
logging.hu.should-log-headers = true
logging.madf.should-log-headers = true
logging.madf.should-log-password = true
logging.api-f-002.should-log-headers = true
logging.f.should-log-headers = true
logging.f-d.should-log-headers = true
logging.f-d.should-log-password = true
logging.copy-d.should-log-headers = false
logging.copy-d.should-log-password = false
logging.d.should-log-headers = false
logging.d.should-log-password = false
logging.e.should-log-headers = true
logging.e.should-log-password = true

what I am trying:

sed -i -E '/should-log=/{s/true/false/;}' infile

but it doesn't work, what am I doing wrong, how should I do it?

Solution

should-log= doesn't match any of the given input lines. You could use something like should-log- or should-log.*= or should-log-.*=.

Also, the {} grouping isn't needed for single command after the address.
