Regex to match multiple instances of a string

Question

I am trying to extract a set of strings from a consul output. What I want to do is remove all instances of the strings which start with

/usr/lib/ocf/resource.d/

Input String

-rwxr-xr-x. 1 root root 971 Sep 22 13:15 /usr/lib/ocf/resource.d/cloud_init_ocf.sh/n-rwxr-xr-x. 1 root root 662 Aug 28 11:25 /usr/lib/ocf/resource.d/credentialmanagercliRestartVM.sh/n-rwxr-xr-x. 1 root root 843 Sep 28 11:13 /usr/lib/ocf/resource.d/jboss_healthcheck.sh

In the above example string that would be the strings of

/usr/lib/ocf/resource.d/cloud_init_ocf.sh
/usr/lib/ocf/resource.d/credentialmanagercliRestartVM.sh
/usr/lib/ocf/resource.d/jboss_healthcheck.sh

What I have tried

I have tried to match the Strings which start with \\\\b/usr/lib/ocf/resource.d/.*\\\\b
I got from here

Code

 regexChecker("\\b/usr/lib/ocf/resource.d/.*\\b", output);

    private ArrayList<String> regexChecker(String regEx, String str2Check) {
        final ArrayList<String> result = new ArrayList<>();
        Pattern checkRegex = Pattern.compile(regEx);
        Matcher regexMatcher = checkRegex.matcher(str2Check);
        String regexMatch;
        while (regexMatcher.find()) {
            if (regexMatcher.group().length() != 0) {
                regexMatch = regexMatcher.group();
                result.add(regexMatch);
            }
        }
        return result;
    }

I think the issue is the /n character which is inserted at the end of each line.

try this way

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main{
    public static void main(String[] args) {

        String regex = "(\\/usr\\/lib\\/ocf\\/resource\\.d\\/[a-zA-Z_]*(\\.sh[\\s|]?)?)";
        String string = "-rwxr-xr-x. 1 root root 971 Sep 22 13:15 /usr/lib/ocf/resource.d/cloud_init_ocf.sh/n-rwxr-xr-x. 1 root root 662 Aug 28 11:25 /usr/lib/ocf/resource.d/credentialmanagercliRestartVM.sh/n-rwxr-xr-x. 1 root root 843 Sep 28 11:13 /usr/lib/ocf/resource.d/jboss_healthcheck.sh";

        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(string);
        int i =1;
        while (matcher.find()) {
                System.out.println("Group " + i++ + ": " + matcher.group(0));
        }
    }
}

and output is

Group 1: /usr/lib/ocf/resource.d/cloud_init_ocf.sh
Group 2: /usr/lib/ocf/resource.d/credentialmanagercliRestartVM.sh
Group 3: /usr/lib/ocf/resource.d/jboss_healthcheck.sh
