Grep multiple keywords from a file
I have a script that will search for a keyword in all the log files. It work just fine.

Code:
 
 LOG_FILES={ "/Sandbox/logs/*" }
 for file in ${LOG_FILES[@]}; do
   grep $1 $file
done

This only works for 1 keyword. What if I want to search for more then 1 keywords, say 4 or maybe even 10 keywords.
So I would enter:
Code:
./myfile.sh 120.2.1.1 Chrome 400 POST

It would check for the IP address, chrome, 400 and POST keywords in all the log files. I see on the internet, they have something like this:
Code:
egrep 'A1|A2|A3' filename

This specify that it will grep the output that is either A1 or A2 or A3 but I would like to grep the output if it is A1 AND A2 AND A3. I'm not sure how to go about doing this? Any help would be greatly appreciated.

tks

SYNOPSIS

     apropos [-d] keyword ...
     whatis [-d] keyword ...

DESCRIPTION

     The apropos utility searches a set of databases looking for documentation matching each keyword and displays the results.	The whatis utility

     The keyword is simply passed to grep(1) allowing for extended regular expression matches.

ENVIRONMENT

     The following environment variables affect the execution of apropos:

     MANLOCALES, MANPATH, PATH
	    Used to find the location of the whatis database files. See manpath(1) for additional information.

     PAGER  Program used to display files.  If unset, more -s is used.

DIAGNOSTICS

     The apropos utility exits 0 if a keyword matched and 1 if no keywords are matched or no whatis databases are found.
