7 | [--no-checkout] [<bad> [<good>...]] [--] [<pathspec>...] | |
8 | reset bisect state and start bisection. | |
9 | git bisect (bad|new) [<rev>] | |
10 | mark <rev> a known-bad revision/ | |
11 | a revision after change in a given property. | |
12 | git bisect (good|old) [<rev>...] | |
13 | mark <rev>... known-good revisions/ | |
14 | revisions before change in a given property. | |
15 | git bisect terms [--term-good | --term-bad] | |
16 | show the terms used for old and new commits (default: bad, good) | |
17 | git bisect skip [(<rev>|<range>)...] | |
18 | mark <rev>... untestable revisions. | |
19 | git bisect next | |
20 | find next bisection to test and check it out. | |
21 | git bisect reset [<commit>] | |
22 | finish bisection search and go back to commit. | |
23 | git bisect visualize | |
24 | show bisect status in gitk. | |
25 | git bisect replay <logfile> | |
