      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,

      guy038
