Answer / rohit
$cat > file.c, on executing this commnd, teh user is
required to manually terminate the execution of this
process, since cat command is expecting the input parameter
to read, but unable to locate so and also for the file.c,
the file et truncated.

cat is used to view the content of the file .
if we have file name like file.c having data

215
216.
if we want to see the data give the command cat file.c.
if we want to over write the data in file.c give command
like
cat > file.c
219 (give ctl+D)
now if we want to see the data give
cat file.c

Answer / maruthi
This is called as purging. we generally use to clear the
contents of the file. The time stamp of the file would not
change. Hence still it would be the current log and the
qouta level of that super user would decrease.
==> It would clear the contents of the file

Answer / amudha
$cat > file.c
$cat is like a normal variable. since this variable is not
defined elsewhere it will not give any o/p.
In this part ">file.c" will create a new empty
file , 'file.c' in the current time stamp

will depend.
