Thread: How to grep multiple values at a time..

Hi all,
I want to grep two or more values i gone through this link
http://www.cyberciti.biz/faq/searching-multiple-words-string-using-grep/
but it is using or.. i mean either of the words if the grep finds it will output.. but my req is both the words should be present..

Coming to my requirement.. i have to check all the below packages are installed or not..
samba
samba-swat
system-config-samba
samba-common
samba-client

depending on the packages installed i have to install remaining packages..
Here is my code..

Code:

rpm -qa | grep samba
                                if [ $? -eq 0 ]
                                        then
                                        echo "Samba package is there.. Now configuring winbind.."
                                        config_samba;

but this code is not conforming what samba packages are installed..

Any help on this will help a lot..

use awk instead

eg 2 conditions ANDed

Code:

... | awk '/condition1/ && /condition2/'

command 1 && command 2 && {echo "Got all" ;} || { echo "at least 1 missing";}

- Can add as many commands between command 1 and command 2.
