Linux Training – Documentation in / usr / share / doc Directory – Linux System Administration Commands


The / usr / share / doc Directory Path

The Linux doc (for doc umentation) directory is the parent directory for a few hundred subdirectories that contain information relating to software components. All of the subdirectories begin with the name of a software package and may end in "-xxx", where the "x" s are numbers that show the current version number of the software.

For example, there may be a subdirectory below doc named bash-x.xx. The x.xx in the directory name, such as 2.05, shows the current version of the bash (Bourne Again Shell) installed on your system.

    Linux Commands Training Tips: The Linux System Administration commands, concepts and tasks covered here apply to ALL other Linux distributions, including: Red Hat, Ubuntu, Kubuntu, Edubuntu, Slackware, Debian, SUSE, openSUSE – and Fedora.

Each of the subdirectories below doc, such as bash-x.xx contain help text files relating to the software components installed on your system.

A huge amount of useful information is included in these directories in files with names like: README, FAQ, INTRO and NEWS . If you are having difficulty with a software component, or even if you just want to know more about it, this is a good place to look for help and information.
