Dear Franklin, thanks for helping.
While the prevous version of your command eat up the string up to the last occurrence of the colon, this one does not seem to affect the file at all.
Files may contain multiple strings with the pattern, and the pattern might appear several times in a string. But I guess that's not the reason why it's not working..

Im attaching an example data file in case..

Thanks a lot.

You have very long lines in the file, that could be the problem, you can try this:

Code:
tr '\n' '~' < file | tr ':' '\n' | sed 's/\(.*THDEA\).*/\1/' |tr '\n' ':' | tr '~' '\n'

Regards
