storing the result of grep in a separate file

问题

I am searching something logs at the following directory

$ cd opt/app/abc/logs

Now the logs folder contains many different logs like

abc.log
def.log
wer.log

Now I need to search something in logs that I am doing n the following way as I wanted to know the names of the files first in which that entry is , Let say I am searching string 456

$bash
$  cd opt/app/abc/logs
$ grep -l 456 *

now I also want that it should store all the records of string 456 in a separate text file at the same location so that after that I can open that file to see the results sum up of string 456. How to achieve this?

回答1:

Just output the command to a file:

grep -l 456 * > somefile.txt

You can do this for any command.

回答2:

Is this what you're looking for?

grep '456' * > outfile
