Find is for finding files , Like you need to find a file named passwd

find / -name "passwd"

output
/etc/passwd
there are several , U have to check that

If we need to check inside the file we need "grep"
grep is a pattern searching tool
like
grep hari /etc/passwd.

what is a pattern ?
do this
ls -l
rwx rwx rwx and lot here file 1
drwxrwxrwx and lot more file 2
.

so forth,
if u need to display a particular pattern like Directory "d"
u can type like that
ls -l | grep 'd'
it will shows all directory
| called PipE, makes input of one command to the output of another one. it is a special file system.
