grep something AND something

Ratzie — Wed, 28 Jan 2004 13:03:20 GMT

I am trying to grep a file, that has this AND that.

grep "s" && "oracle"

does not seem to work.

Hi,

Your question isn't quite clear to me. If you are searching for lines that contain both s and oracle, a simple way is

grep "oracle" file|grep "s"

If you are looking for lines that contain either s or oracle or both then

grep -E -i 'oracle|s' file

or

grep -i -e 'oracle' -e 's' file

How about

grep "s" |grep "oracle"

?

I have tried that, but I need it to contain BOTH!

Can you give us an example?

$cat data

oracle a fine word
s is a letter
s not there in oracle
ofcourse s is not there in oracle
but o in oracle

$grep oracle data |grep s
s not there in oracle
ofcourse s is not there in oracle

??

If you are trying to match multiple patterns then use -e option in grep

As Sri points out, the pipe construct ( grep "s" | grep "oracle" ) should give you what you're looking for. Can you provide details of how/where you think it's failing?

He's trying to do a grep with an AND.

Give me the lines where BOTH "s" and "oracle" appear in the same line.

grep ("s" -a "oracle") file

I can't think of any way to do it!

Hi,

you can try:
grep -E ".*text1.*text2|.*text2.*text1" file

Right...
The leading '.*' for 'any characters' do not seem to be needed, giving:

grep -E "oracle.*s|s.*oracle"

but normally you grab for a double grep...

Sri's answer is right -- I do this all the time ..
grep -i -e 'oracle' -e 's' file

Note -- BOTH THINGS YOU ARE LOOKING FOR *MUST* have the -e in front of it. That screwed me up before I got the hang of it and I think this could be what you are missing. The following command does not work because it's missing the other "-e":
grep -i oracle -e file

(Note, the -i is optional so that it's case-insensitive)

Here is my test file 3 lines

#cat toddfile
s and oracle
s only
oracle only

Here is my test...

root:/root
# grep s /tmp/toddfile
s and oracle
s only

root:/root
# grep -e s -e oracle /tmp/toddfile
s and oracle
oracle only
s only

root:/root
# grep s |grep oracle /tmp/toddfile
s and oracle
oracle only

root:/root
# grep s /tmp/toddfile |grep oracle
s and oracle

See the last one shows your example of only showing those lines with both s and oracle on them...

Hope this helps.
