how to search for string that includes folder separator ?

I want to select only second line.
I want to search for any line that has both -> [ 'userA' AND 'aaaaaaa/' ]

Code:

 
input.txt
/userA/aaaaaaabbb/jakarta
/userA/aaaaaaa/jakarta
/userB/aaaaaaabbb/jakarta
/userB/aaaaaaa/jakarta

This command does have effect of --> [ 'userA' OR 'aaaaaaa/' ]

Code:

 
$>cat input.txt | /usr/xpg4/bin/grep -E 'userA|aaaaaaa/'
/userA/aaaaaaabbb/jakarta
/userA/aaaaaaa/jakarta
/userB/aaaaaaa/jakarta

I know I can do it by executing grep two times, with piping..

Code:

 
$> cat input.txt | grep 'userA' | grep 'aaaaaaa/'
/userA/aaaaaaa/jakarta

But I am looking for a way to do this in one command,, simplest possible way..!?

Dr.House,Verdipollo

Yes both of your commands work with initial input.txt file,, Please check the new input.txt file that more accurately reflects my requirement..

My search strings can be seperated by any number of other strings..Sorry for the confusion..

Code:

input.txt
/userA/bla/bla/bla/../aaaaaaabbb/jakarta
/userA//bla/bla/../../aaaaaaa/jakarta
/userB/bla/../aaaaaaabbb/jakarta
/userB/bla/aaaaaaa/jakarta

I want all the lines that have both string "userA" AND "aaaaaaa/". which may be seperated by any number of other strings.

Code:

this works
grep -E 'userA.*aaaaaaa/+' input.txt

What does that + do at the end ?

Smilie

Useless use of cat

kchinnam, this is somewhat like a 1:1 sed translation of verdepollo's grep command, but without that "+" sign.

Code:

sed '/userA.*aaaaaaa\//!d' input.txt
