hi .

I have some kind of desired lines at the log file :
---> Time   17.217us: Receiving preamble on GMII
---> Time   17.585us: Packet Received from port 2
---> Time   13.478us: Sending Pkt on GMII
...
the key words are :

Receiving , Received , Sending

how to write a grep command to get as an expression : "exp1 or exp2 or exp3"

can I do this with larger groups of key words ?

you could actually use egrep

egrep "exp1|exp2|exp3" fileName


or use grep in the following manner

grep -e pattern1 -e patter2 ...fileName
