What is the difference between $ and # signs in Linux environment? As I started working on Linux and I found that both are different. I mean they do have different set of privileges...?
[root@localhost ~]# and [tom@localhost ~]$.

In short, if the screen shows a dollar sign ($) or hash (#) on the left of the blinking cursor, you are in a command-line environment.
$, #, % symbols indicate the user account type you are logged in to.
- Dollar sign (
$) means you are a normal user. - hash (
#) means you are the system administrator (root). - In the C shell, the prompt ends with a percentage sign (
%).
There are differences on prompts in different Unix or GNU/Linux distributions because of their default settings. For example, the prompt of Debian/Ubuntu is guest@linux:~$, the one of Fedora/CentOS/RedHat is [guest@linux ~]$ and the one of SuSE Linux/OpenSUSE is guest@linux:~>. In general, the prompt usually show the login user name, machine hostname, and current working directory and ended with a dollar ($), percentage (%), or hash (#) sign.
guest@linux:~$
guest- username: the user account you are logged in to.linux- machine hostname: the machine you are operating.~- current working directory: the directory you are in. Tilde (~) means home directory, i.e. the default directory when first logging in.

@GayanWeerakutti What does dollar sign do in this command
chattr +i "$(realpath /etc/resolv.conf)"I found it on another question and I need clarification. Thanks. – Shayan Aug 23 '19 at 18:07 -
1@GayanWeerakutti It makes sense because
/etc/resolv.confwas a symlink in pre-systemd days to/run/resolvconf/resolv.conffile. Not entirely sure how it's used now, though. Andchattrapparently doesn't work on symlinks – Sergiy Kolodyazhnyy Aug 24 '19 at 8:05 -
