Use of grep or egrep 1

[MaheshRathi]

Hi,

I am not able to use grep or egrep to get the matched lines for multiple patterns. For E.g. I want to get the lines matching to either "This is good" or "This is better" pattern.
The file can be like this ...

I say This is good or bad.
you say This is better may be.
Nobody knows how to get what is good or bad
then try it or do something

These are the content of file and want to get the lines 1,2 out of four.

Appreciate if you can provide me some pointers.
thanks,
Mahesh

Try this:

egrep 'This is (good|better)' /path/to/file

Hope This Help

...or this way

grep -E 'This is Good|This is better' /path/to/file

Both suggestions should work for you.

Hi,

Could someone help with the syntax here? I am trying to use four variables as a part of egrep

egrep "'$YDMON $YDAY'"|"'$TMON $TDAY'"

Thanks in advance

Replace this:
egrep "'$YDMON $YDAY'"|"'$TMON $TDAY'"
By this:
egrep "($YDMON $YDAY|$TMON $TDAY)"

Hope This Helps, PH.
