Hello @ani-rodet and All,

Just one regex S/R and you’re done :-)

So :

Open the Replace dialoag ( Ctrl + H )
SEARCH (?-s)^.*[[:xdigit:]]{40}.*\R
REPLACE Leave EMPTY
Tick the Wrap around option, if necessary
Select the Regular expression search mode
Click once on the Replace All button or several times on the Replace button

Notes :

The first part (?-s) ensures that the regex char . will match a single standard character, only ( not EOL ones )
Then the part ^.* searches for the longest, even EMPTY, range of characters till …
Now, the part [[:xdigit:]]{40} looks for, exactly, 40 hexadecimal characters
The final part .*\R selects all the remaining characters of current line with its like break ( \R )
The overall match is just deleted as the replacement zone is empty

Best Regards,
