Print a git log (in reverse order) giving a reference relative to HEAD. HEAD (the current revision) can also be referred to as HEAD~0 The previous revision is HEAD~1 then HEAD~2 etc. . Add line numbers to the git output, starting at zero: $ ... | nl -v0 | ... . Insert the string 'HEAD~' before the number using sed: $ ... | sed 's/^ \+/&HEAD~/' .
