Hi! This issue has been reported downstream at Git for Windows project, here: https://github.com/git-for-windows/git/issues/1841
Git for Windows includes a set of GNU utilities. IIRC those come from MinGW project. Summarizing from the downstream report: Actual output, with grep 3.1 (in Git for Windows 2.19.0): [[[ $ grep --version grep (GNU grep) 3.1 ... $ cat > foo.txt foo: bar baz: $ unix2dos foo.txt unix2dos: converting file foo.txt to DOS format... $ grep ':$' < foo.txt $ grep --line-regexp '.*:' foo.txt $ grep --line-regexp '.*:' < foo.txt ]]] Expected output, observable with grep 3.0 (in Git for Windows 2.18.0), or if I run dos2unix on the file: [[[ $ cp foo.txt foo2.txt $ dos2unix foo2.txt dos2unix: converting file foo2.txt to Unix format... $ grep ':$' < foo2.txt foo: baz: $ grep --line-regexp '.*:' foo2.txt foo: baz: $ grep --line-regexp '.*:' < foo2.txt foo: baz: ]]] I guess that this regression is related to the following changes listed in the NEWS file, apparently implemented via #25707: [[[ The following changes affect only MS-Windows platforms. First, the --binary (-U) option now governs whether binary I/O is used, instead of a heuristic that was sometimes incorrect. Second, the --unix-byte-offsets (-u) option now has no effect on MS-Windows too. ]]] Best regards, Konstantin Kolinko
