Unix

Its opens the file testing with the program vi.

Use the 'du' command in the directory you are interested in.

Solaris is a specific version of Unix; the term 'Unix' refers to a classification, and several vendors provide a Unix-like environment. So, in a sense, Unix and Solaris are the same thing.

The usual difficulty that people report concerning UNIX is the use of the command line. The command line has a lot of power and the commands may seem somewhat arcane at times. Like anything else, you have to study what the commands do and how to use them to harness the power of UNIX, but once you do that it isn't that difficult to use.

You rename a directory the same way you rename a file. Use the 'mv' command to rename it.

MS-DOS wasn't very complicated OS.

Some people would say that it's because it was made by Microsoft, and as you know most of Microsoft products lack functionality compared to others(Windows, MS-DOS, NTFS, etc.)

The 'ps' command may differ slightly in different versions of unix operating systems. It is usually better to use the 'man ps' command or the 'info ps' command to see the options that are available for your distribution.

decoy system is a grouping of soiled tablewares in soiled dish table according to size and shapes.

I don't know about a SEQ command, but the 'seq' command in Unix will print a sequence of numbers from first to last, with a given increment.

Use the 'man seq' command to find out how to use it.

I can't find any official reference to a 'pz' file - are you referring to a compressed PNG?

The PHP website has a comprehensive online manual that can explain most aspects of PHP, including its installation. See the related links for a constantly-updated PHP installation guide.

ms windows is byfar less stable than unix

Unix is one of the oldest but still most popular Operating Systems. It was invented in 1969 at AT&T Bell Labs by Ken Thompson and Dennis Ritchie. All the contemporary operating systems of Solaris, HP-UX, Linux, AIX are variants of Unix.

'cu' stands for Call Unix. It used to be used for calling dialup services from one Unix to another. Hardly used anymore with networks (which are much faster)

The easiest way would be:

cat file1 > file2

API comprises of lanuage libraries and systm call interface

AUI comprises unix shell commands and application programe

Somewhat unclear exactly what you want to do; please be more specific.

It is isn't a configuration difference to go between single user and multi-user modes in Unix. You use a different 'run' level for that. The 'init' levels can determine whether you are operating in a single user mode or a multiple user mode. Single user mode is usually reserved for system administration.

See related link.

#!/bin/sh

echo "Please enter the name of a user:"

read USER

who|grep $USER > /tmp/usertest &

sleep 5

if [ -s /tmp/usertest ]

then echo "User is logged in"

else echo "User is not logged in"

fi

rm /tmp/usertest

I don't know how anyone could possibly work out how many programs there are. Don't forget, it's not just New Zealand, it's the whole world. What you'd have to (this would be quite unlikely to do) is travel to all the different countries and look in each different T.V guide and then you can add all the programs from the different countries up but nobody yet knows how many programs there are.

">" redirects all output to a file, overwriting any preexisting content.

You will have to be more specific about what you intend to do. In general, a shell script by itself does not read file information and then do something with it. There may be calls to other scripting languages such as awk, perl, python, etc., that will actually read the information and process the data.

Stop error (BSOD) that occurs during startup.

A stop error can be caused by a corrupted registry, a system file that is missing or damaged, a device driver that is missing or damaged, bad memory, or a corrupted or failing hard drive. Use the Microsoft web site to research the exact error message and error code. Use the Startup Repair tool and then examine the log file it creates at C:\Windows\System32\LogFiles\Srt\Srttrail.txt.

The trap command is used in a shell script to intercept certain types of software signals; usually it is used to do a "graceful" cleanup when the shell program is interrupted.
