DOS command syntax
Back in the days before
Microsoft Windows dominated the PC market, operating system were
controlled by commands. Prior to MS-Windows, PC users were required
to learn these commands in order to perform routine tasks. During
the 1980s, Microsoft DOS dominated the PC market while the early UNIX
command systems were used on larger multi-processing servers.
The main difference
between UNIX and DOS is that DOS was originally designed for single-user
systems, while UNIX was designed for systems with many users.
While PC’s have
evolved into GUI interfaces such as Windows, UNIX systems have never
evolved into GUI environments. Hence, The Oracle professional must
master a bewildering number of cryptic UNIX commands in order to manage
their Oracle databases, both on Windows NT and UNIX.
One of the most
confounding issues for the UNIX neophyte is being confronted with a
complex UNIX command. The cryptic nature of UNIX is such that even
the most seasoned UNIX professional may have trouble deciphering the
purpose of the command.
Because UNIX and MS-DOS
were developed at the same time they share some common syntax, and the
UNIX neophyte will be happy to find many common commands and concepts.
The list below shows some of the commonality between UNIX and MS-DOS
