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
