I have a file which contains so many lines and variable
number of lines are treated as a record. For example
*first ooooo xxxxx
ttttt mmmm vvvvvvv
*end uuu bbbb
*first kkkkvvvvvv
nnnn mmmmm kkkkk
fffff gggg ffff
kkkk
lllll
*end.
Here the lines from *first to *end are treated as a record.
The number of lines between *first and *end is not same for
all the records.
Suppose there are 100 records (or number of records are not
predefined)like the format given in the above example. Now
the entire file needs to split into two files, first having
40 and remaining in the second file.
Can we split using sort utility? If possible then what is
the sort card?

Implement a command console for changing settings on a
particular object. The command console should allow you to
enter a string and will return the response (very similar to
a terminal session). The commands are as follows:
SET propertyname=newvalue will change the target
object’s member named “propertyname” to have a value equal
to “newvalue”. If the input value is incompatible (i.e. an
int being set to a string), print out an appropriate error
message.
GET propertyname will print out the current value of
the target object’s member named “propertyname”.
GET * will print out a list of all target object
members and their current values.
The system should be extensible for future commands and
should accept an arbitrary object, such that another
developer could insert another object into the system and
rely on the command console to get and set the properties
correctly.

U hv to enter a range from a and b and search hw many no.
of times a pattern n. occurs between the range a and b.
Eg :i/p:enter range :0 100
Enter pattern: 13
o/p: the no. times 13 occurred betwwn 0 to 100:1
Eg :i/p:enter range :100 1000
Enter pattern: 13
o/p: the no. times 13 occurred betwwn 100 to 1000:
(in this 13,113,131,132,133…139,213,313,…913 all these will
be counted)
