Answer / brijmohan
None of the option will work.
Because "grep first second third" this command will search
for the same pattern and but it should grep "first second
third" instead of grep first second third.

Answer / sathe santosh
The above command will not work.
grep searches the 1st argument in 2nd argument(filename).
The filename has multiple patterns.
example:
cat 1.lst
hi
hello
bye
see the below message.
grep hi hello 1.lst
grep: can't open hello
1.lst:hi
same can be done using below command.
grep -e hi -e hello 1.lst
hi
hello
