I'm looking for a program that can read lines from many files at once and allows editing them and saving them back after changes. It may seem a weird idea at first glance, but it's quite simple and the software can be very useful for working with configurations. Especially those spread like this:tomas@tomas:/etc/sysctl.d$ ls10-console-messages.conf  10-link-restrictions.conf  10-ptrace.conf    README10-ipv6-privacy.conf      10-magic-sysrq.conf        10-zeropage.conf10-kernel-hardening.conf  10-network-security.conf   99-sysctl.confSo it would be no surprise if it already exists.To rephrase, I'd like to get from all of the files from the listing above (but README) those lines that are either:uncommentedcommented with a character following right after #Then I want to be able to comment, uncomment, or change the value - interactively, as in a text editor. And finally I want to save the changes.Is there a special mode to vim or other popular terminal editors that facilitates this? Or is there possibly an edition tool designed for this kind of tasks in particular?
