Q  87. What are different types of views?Explain the difference.

Views are required in order to use Clearcase. A unique view assigned to a user will:

• allow a developer access to the VOB data (source code storage)
• provide a workspace are where users can privately modify VOB data without disturbing the view of the VOB data held by other developers. Changes are only accessible by others when a file is checked into the VOB from the users private space.

There are three types of views:

• Snapshot view: Changes and updates by others are not available to a snapshot view until a new "snapshot" is taken.
• Web view: accessible from Clearcase Web interface. Similar to a snapshot view.
• Dynamic view: access to all versions of VOB elements and view private objects as they are checked into the VOB

What is difference between $*, $@ , $_and $0?

Q.46 . What is difference between $*, $@ , $_and $0?

$#	The number of arguments supplied to a script.
$*	All the arguments are double quoted. If a script receives two arguments, $* is equivalent to $1 $2.  The "$*" special parameter takes the entire list as one argument with spaces between
$@	All the arguments are individually double quoted. If a script receives two arguments, $@ is equivalent to $1 $2. The "$@" special parameter takes the entire list and separates it into separate arguments.
$?	The exit status of the last command executed.
$0	Gives File Name

test.sh

#!/bin/sh

echo "File Name: $0"

echo "First Parameter : $1"

echo "Second Parameter : $2"

echo "Quoted Values: $@"

echo "Quoted Values: $*"

echo "Total Number of Parameters : $#"

Here is a sample run for the above script −

$./test.sh Foo Bar

File Name : ./test.sh

First Parameter : Foo

Second Parameter : Bar

Quoted Values: Foo Bar

Quoted Values: Foo Bar

Total Number of Parameters : 2
