Grep multiple words in a single file

Shell Programming and Scripting
1

Hello All,

I'm a newbie/rookie in Shell scipting. I've done oracle export of a table using Export utility. When I do export, it generates 2 files.
1> .dmp file
2> .dmp.log file.

In .dmp.log file I have to search for a sentence which goes like '0 records have been inserted' and then I've to check for 'Export terminated succesfully without warnings'.
For a single sentence I can do

grep 'Export terminated succesfully without warnings'. filename.dmp.log

Could you please help me how to find multiple sentences. I'm not sure if we could use compound statement here.

Thank you,
Sam.

grep -E 'Export terminated succesfully without warnings|0 records have been inserted' filename.dmp.log

Some grep implementations don't support the standard -E option,
if the command above doesn't work, try using egrep , instead of grep -E .
