• Getting a list of all children of a given commit

  - by intuited

  I'd like to run git filter-branch on all children of a given commit. This doesn't seem to be an easy task, since there doesn't appear to be a way to tell git rev-list to only return children of a particular commit. Using the .. syntax won't work because it will also include the parent commits of any merge within that range. Am I missing something here?

• Ignoring certain chars globally

  - by shi kui

  Consider it that '_'s in a number doesn't change that number's value so 1000==1_000==10_00. The Problem: given numbers like 1_244_23 1412_2 1_1111 etc..., how could I decide whether certain number appears in that collection? For example: 1244_23 yes, 11_111 yes, 1412_1 no. How could using regex to solve this? I mean, if I could tell the regex engine just ignore these '_''s when matching then this problem becomes trivial? How could I do so?
