How about...
cat file1 | perl -e 'while(<>){ next if !/IMO/; print $_;}'
If the lines can only begin with IMO then:
cat file1 | perl -e 'while(<>){ next if !/\bIMO/; print $_;}'
If case is not important then:
cat file1 | perl -e 'while(<>){ next if !/\bIMO/i; print $_;}'
If you have multiple words to search for, then create another file named file2 and enter the search words:
vi file2 apple orange banana grep -f file2 file1
From the unix command-line... file2 is the list of words to search for from lines in file1... Note: you may have to run "dos2unix file2" to remove LF/CR or use chomp somehow...
