@Scrutinizer:

Thanks. This one works as needed

Code:
grep " have the same position." input.log | awk -v re="^'exm" ' { if (! ( $5  ~ re )) print $0 }'

It's hard for me not use if and parentheses. I don't know how you folks easily swim around without if, and other syntax. Smilie
I added ! in if because I need only those lines that don't have 'exm in fifth column.

Edited: for more details.

The proper (portable) escape for a ' within a ' ' string is
Code:
echo 'a '\'' character'

Explanation: the \' must be outside the ' ' string, so the latter is split into two parts with the \' in between.
Code:
echo 'a '\'' character'

Code:
grep " have the same position." input.log | awk ' { if( $5 ~ "^\x027" "exm" ){print $0} }  '
