Q:

How to quickly mark resolution having conflicts during rebase?

this is a part of my git status
# Unmerged paths:
#   (use "git reset HEAD <file>..." to unstage)
#   (use "git add/rm <file>..." as appropriate to mark resolution)

How can I easily and quickly make git rm on each of this file, knowing that in folder ../../src/generic/ there are a lot of other files, which I don't want to remove.

A:

There's this really great pair of aliases I picked up from the git wiki a while back (it's currently down along with kernel.org):
edit-unmerged = \
    "!f() { git ls-files --unmerged | cut -f2 | sort -u ; }; vim `
add-unmerged = \
    "!f() { git ls-files --unmerged | cut -f2 | sort -u ; }; git add `f`"

This could be reimplemented in terms of git status --porcelain, which didn't exist when the tip was written, which would make it easier to rewrite edit-unmerged to avoid including deletion conflicts, since usually you want to delete/keep those, not edit them. But add-unmerged fits your use case exactly!
Something like this (untested):
add-unmerged = \
    "!f() { git status --porcelain | grep '^[ADU][ADU]' | cut -d" " -f2 }; git add `f`"
edit-unmerged = \
    "!f() { git status --porcelain | grep '^UU' | cut -d" " -f2 }; git add `f`"

with tweaking on the second pattern until it includes only the types of conflicts you like to edit. You definitely want UU; you might also want AU/UA, and maybe even AA. A for added, D for deleted, U for unmerged (modified).
