Generally, I would pass the results from grep to another grep statement.

Code:

grep condition1 file|grep condition2

using awk

Code:

awk '/condition1/ && /condition2/' file

using egrep

Code:

egrep "condition1.*condition2|condition2.*condition1" file

using grep

Code:

grep -E "condition1.*condition2|condition2.*condition1" file
