use of xargs command

Hi Everybody,
Can you explain the difference between the following commands:

1. find . -print|xargs grep -i dba_2pc_pending

2. find . -print|grep -i dba_2pc_pending

Is this for a homework assignment? Perhaps the manual pages will help.

Its not a homework.

I am going through a tutorial and I have across this.

I tried the man pages, but couldn't really understand what it is talking about.

what tutorial?

The book I was talking about is Unix for Oracle DBAs

it is very aparent if you do a test what the differance between those 2 commands are.

Code:

# ls -l ; cat one two three
total 6
-rw-r--r--   1 root     other          2 Oct 30 12:43 one
-rw-r--r--   1 root     other          2 Oct 30 12:43 three
-rw-r--r--   1 root     other          2 Oct 30 12:43 two
1
2
3
# find . -print|xargs grep 2
./two:2
# find . -print| grep 2
#

what do you notice about this example. i am sure it looks something along the same basis as in your book.

i could just come out and say what the differance is. but i dont think you will honestly learn and remember the differance. so i am trying to make you think about it.
