Linux Directories!

[nickole]

Hello All,

Currently I am dabbling with Redhat 9.0 and exploring the world of Linux.
Here is a list of directory names:
/var
/usr
/etc
/proc
/initrd
/opt

I would like to know What do these directories represent and their significance.

Any answers...
Aaahoy

/var

contains various variable data which changes constantly ... logs of your system are stored there in /var/log .... you can look at logs by typing cat /var/log/messages


/usr

contains user programs their configuration files, graphics for programs etc....

/etc

contains configuration files of your linux system ( service, start-up scripts, X11 server config files etc.... everything that has to be configured for your linux to work !


/proc

proc is virtual directory which is mounted on linux startup.... it contains various linux kernel data

/initrd

like the name says ... it contains some init scripts

/opt

usually this is directory where you store third party programs such as openoffice.org ......

Thats it
