Linux program/bash script to check file settings and determine if they are correct

Linux Bash Script or program Short overview: I need a script or program that checks particular Linux files for specific settings. It compares the value of those settings with a predetermined number/string and verifies they are correct. The program needs to at least work on Linux 6 and 7. Preferably 5 as well. But each version will have different files to check and values. Small UI that uses user input to select the Linux OS version. E.g.: ******************************* Apex Linux Configuration Checker * Select OS to check: * Linux 5 * Linux 6 * Linux 7 * ******************************* Depending on user’s input, the script will check multiple OS files for the current setting, and compare it to what the setting “should” be. If this condition is correct, the program prints “Pass” in green. If the condition is incorrect, the program prints “Fail” in red. The program will print a title/file name/identifier for each line it checks. For example: “/etc/shadow” --------------------------------------Pass “/etc/grub2/[login to view URL]”------------------------------Pass “/etc/[login to view URL]”-------------------------------------Fail Some files will need to be printed, instead of checked. This would be because the file changes often, or enough that an automatic check couldn’t be reliably programmed. For example: “Symantec engine and definition date Engine: 14.x.x Date: 02/14/2019” “[login to view URL] hash and kernel version #Hash: xxxxxxxxxxxxxxxxxxxxxxxxx Kernel: xxxxxxxxxxxxxxxxxxxxxxxx” “MOTD, kscreensaver, [login to view URL] <printed message>” There should be a pause between the pass/fail section of the printout, and the section that prints the messages that waits for the user to press any key. For example “Pass/Fail section complete. Press any key to continue to printed files” After each print of file, the program should wait for the user to press a key to continue, and each section should be easily distinguished, by maybe a character divider and/or color. For example: Press any key to continue to the next file /etc/[login to view URL]: <Paragraph of message> Press any key to continue to the next file ****Possibly print only conditions that FAIL. If pass, just print pass.
