Easy with regular expressions !

• Open The Replace dialoag ( Ctrl + H )

• SEARCH (?-s)(^.+:[[:xdigit:]]{32}).+

• REPLACE \1

• 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

• Then the part ^.+: searches for the longest zone ending with a : character

• Now, the part [[:xdigit:]]{32} simply selects 32 hexadecimal characters

• As the part ^.+:[[:xdigit:]]{32} is embedded in parentheses , its present value is stored as group 1, which will be rewritten, during replacement

• The final part .+, searching for the remainder of each line, is deleted, during replacement, as not stored in a group
