Is it possible to grep two or more patterns ?

[yc_2]

Hi,

Is it possible to grep two or more patterns ?

eg: I want to grep root, daemon and adm in password file.


Thanks in advance,
YC

Hi,

You can use grep -e

# cat /etc/passwd | grep -e root -e daemon -e adm

Hi,

Yes, Try :

# grep -e root -e adm -e daemon /etc/passwd


Cheers!

$ cat /etc/passwd | grep root | grep daemon | grep adm

Yes, you can grep two or more patterns in one go

1 - grep -e -e ... ...

2 - egrep "|||..." ....

I prefer method 2 as it is less typing
