what is the use of "grep" command?..

Answer / kiran sangeri

grep is one of many standard UNIX utilities. It searches
files for specified words or patterns. First clear the
screen, then type
% grep science science.txt
As you can see, grep has printed out each line containg the
word science.
Or has it ????
Try typing
% grep Science science.txt
The grep command is case sensitive; it distinguishes
between Science and science.
To ignore upper/lower case distinctions, use the -i option,
i.e. type
% grep -i science science.txt
To search for a phrase or pattern, you must enclose it in
single quotes (the apostrophe symbol). For example to
search for spinning top, type
% grep -i 'spinning top' science.txt
Some of the other options of grep are:
-v display those lines that do NOT match
-n precede each matching line with the line number
-c print only the total count of matched lines
