Linux Filesystem Organization
Directories for Storing Files on a Machine
Temporary Files:
The standard ramdisk on an EMAC OE machine, used for storing temporary files of any kind, is located in:
/var/volatile/
Executables:
There are two different directories commonly used for installing custom written software. The directories listed here are given according to the Free Desktop Standard, which is a standard by which most Linux systems conform.
This first directory is the standard location for executables which were written for a specific, individual machine:
/usr/local/bin
The next directory is intended to be used for non-free (Company developed and owned) software:
/opt/CompanyName/bin
Since the CompanyName is specific to the company which produced the software, this directory will often also contain some other standard subdirectories:
/opt/CompanyName/etc/ /opt/CompanyName/usr/ /opt/CompanyName/lib/ /opt/CompanyName/var/
Configuration Files:
Configuration files should either go in:
/etc/
Or, if a directory in /opt/ was created, in:
/opt/CompanyName/etc/
Initialization Scripts:
Scripts which are used to automatically start a program on boot and, if needed, stop it on shutdown, should be located here:
/etc/init.d/
