I work in at a telecom company and in some cases I need to search for multiple numbers around a specific time. I am using Ubuntu sever 10.04. When I search for a call my normal expression is:
grep 5555551234 20120719-12*
20120719-12* is the date and time (GMT) for the number I am looking for.
When I use
grep 5555551234 20120719-18* | 5555551235 20120719-18*
I will only get a return on the first number
If I use
grep 5555551234 | 5555551235 20120719-18*
-sh 5555551235 not found
Any feedback would be appreciated..
