Conditional Replace

[cempey]

Hello,

I have a list of files in the format aa_bb_fname_lname_ccc.jpg. I would like to change the underscore between fname and lname to a space. aa, bb are both two charachter strings, fname, lname and ccc may be various lengths. It will always be the first underscore I want to change beyond the 7th position.

Can BRU do this, and if so, what regex to I need?

Hi, Chris:
You got me a little confused with the "first underscore [...] beyond the 7th position" part.
From what you say in your second sentence, I understand that you want to change the names from "aa_bb_fname_lname_ccc.jpg" to "aa_bb_fname lname_ccc.jpg" (where "aa" and "bb" always have two charachters, and "fname", "lname" and "ccc" may vary their lengths). In that case you should use the following RegEx:

MATCH: (.._.._)(.*?)_(.*)
REPLACE: \1\2 \3

Regards,

Gabriel.

Thank you Gabriel,

That worked perfectly and had the additional benefit of giving me some understanding of Regex. Some playing around with this search and replace has taught me a valuable lesson that I will be able to use in the future.

Sincerely,
Chris
