Shell scripts.
Possibly the most powerful tool in the systems administrators
box. Shell scripts can be developed quickly, deployed rapidly
and maintained consistently across a multitude of UNIX and Linux
distributions.
All City Linux shell scripts have version control and
repositories can be maintained on your own administration servers,
on City Linux servers or in the cloud on global hubs (eg. Github).
If you need scripts testing but only have a production environment
available, testing can be done on a virtual server at City Linux
replicating your OS distribution and patch level.
Scripts can be monitored for unauthorised change and authorised
versions restored in the blink of an eye.

Documentation.
Together with unauthorised change and lack of version control
lack of documentation is an endemic problem for organisations both
large and small.
The ease with which it is possible to rapidly generate powerful shell
scripted tools militates against expending more time on documenting
the work. When things go wrong or updates and changes are required
it may take some time to determine how exactly the script works or
why that particularly bizarre looking formulation was used.
City Linux shell scripts, short or long, complex or simple
can be fully documented. The script itself contains notes where
unusual algorithms or structures are used and a man page is created
whereby the documentation is fully integrated into the system and
is available whether using a serial terminal, local GUI, a remote
virtual device or a web browser.
Sample shell scripts.
Choose a script from the left hand menu to select the
manual page for the script. From the man page you can click
through to the script itself.
