[SOLVED] Is there any other way to find configuration files other that from man pages?

shanebagel · 06-16-2022, 02:28 PM

I have trouble remembering where exactly each configuration file is located in unix/linux systems (there are alot lol)

Is there a more effective way to find where exactly each configuration file is located?

For example: grub? Other than reading through manual pages - I can't seem to find any info on where the configuration files are (other than googling for it - how would I find this information in a test environment like the RHCSA?)

I haven't used Red Hat ever, so I can't help you with that, srry. Though, if you're looking for howtos and where configuration files are located you should check out some of the wikis that many distros have.

I mainly use Debian and Arch ones, but you may want to check if Red Hat has one too.

There may be some minor differences between one distro and another, but they are generally all the same. For example, for you to update GRUB config, in Arch you type

Code:

# grub-mkconfig -o /boot/grub/grub.cfg

, but in Debian you use

Code:

# update-grub

. Btw, they both use the same configuration file, located at

Code:

/etc/default/grub

.

Hope it helps! :^)

In all the cert exams I've been in, it's pretty much expected that you know what and where config files are, and help files/manuals may not be available. It helps to know the man section numbers, e.g. 5 is for config files.

add /etc/grub.d/ dir to that list

also distros mostly conform to XDG specs
https://specifications.freedesktop.o...%20be%20stored.

in other words configs are normally searched, with home configs tending to be used ahead of system wide here
~./config
~./
/etc/
/usr/local/etc

I'm sorry what?

Code:

man grub-
grub-bios-setup       grub-macbless         grub-mknetdir         grub-reboot
grub-editenv          grub-menulst2cfg      grub-mkpasswd-pbkdf2  grub-render-label
grub-file             grub-mkconfig         grub-mkrelpath        grub-script-check
grub-fstest           grub-mkdevicemap      grub-mkrescue         grub-set-default
grub-glue-efi         grub-mkfont           grub-mkstandalone     grub-syslinux2cfg
grub-install          grub-mkimage          grub-mount
grub-kbdcomp          grub-mklayout         grub-probe

You sure you checked all those?

Also make sure to try

Code:

info grub
