Why are so many dirs used in solaris hierarchy?

wrapster · 06-19-2008, 01:54 AM

Hi all,

I would like to know the difference between the different dir structures present in solaris!!!

Meaning what does /usr contain, /etc ,/opt/ ,so on...
I know what /usr and /etc are used for.
But why are /opt /bin /sbin /var and many more that i have missed

I would appreciate if anyone can direct me to a link where i can have extensive study of all these dirs.

thanks

A few seconds with good old google gave me this:

Quote:

/ (root)

The directory located at the top of the Unix file system. It is represented by the "/" (forward slash) character.

/usr Contains commands and programs for system-level usage and administration.

/var Contains system log files and spooling files, which grow in size with system usage.

/home Contains user home directories.

/opt Contains optional third-party software and applications.

/tmp Contains temporary files, which are cleared each time the system is booted.

/proc Contains information about all active processes.

On linux, /sbin contains special binary files, used for system administration tasks etc.
/bin, is normal binary files.
/lost+found is a good one.. you find that with ext2 filesystems after a fsck has found errors.

I'm sure there is more out there.. Try reading "Solaris Administration" guides..

I'm starting on OpenSolaris and found this handy.
The "Intro part 1" should help for this particular query.

The filesystem hierarchy is also well documented in the manual pages.

Just run: "man filesystem"
