Removal +of a file is staged with gitlink:git-rm[1]. After building the +state to be committed incrementally with these commands, `git +commit` (without any pathname parameter) is used to record what +has been staged so far. This is the most basic form of the +command. An example: + +------------ +$ edit hello.c +$ git rm goodbye.c +$ git add hello.c +$ git commit +------------ + +//////////// +We should fix 'git rm' to remove goodbye.c from both index and +working tree for the above example. +//////////// + +Instead of staging files after each individual change, you can +tell `git commit` to notice the changes to the files whose +contents are tracked in +your working tree and do corresponding `git add` and `git rm` +for you. That is, this example does the same as the earlier +example if there is no other change in your working tree: + +------------ +$ edit hello.c +$ rm goodbye.c +$ git commit -a +------------ + +The command `git commit -a` first looks at your working tree, +notices that you have modified hello.c and removed goodbye.c, +and performs necessary `git add` and `git rm` for you. + +After staging changes to many files, you can alter the order the +changes are recorded in, by giving pathnames to `git commit`. +When pathnames are given, the command makes a commit that +only records the changes made to the named paths: + +------------ +$ edit hello.c hello.h +$ git add hello.c hello.h +$ edit Makefile +$ git commit Makefile +------------ + +This makes a commit that records the modification to `Makefile`. +The changes staged for `hello.c` and `hello.h` are not included +in the resulting commit. However, their changes are not lost -- +they are still staged and merely held back. After the above +sequence, if you do: + +------------ +$ git commit +------------ + +this second commit would record the changes to `hello.c` and +`hello.h` as expected. + +After a merge (initiated by either gitlink:git-merge[1] or +gitlink:git-pull[1]) stops because of conflicts, cleanly merged +paths are already staged to be committed for you, and paths that +conflicted are left in unmerged state. You would have to first +check which paths are conflicting with gitlink:git-status[1] +and after fixing them manually in your working tree, you would +stage the result as usual with gitlink:git-add[1]: + +------------ +$ git status | grep unmerged +unmerged: hello.c +$ edit hello.c +$ git add hello.c +------------ + +After resolving conflicts and staging the result, `git ls-files -u` +would stop mentioning the conflicted path. When you are done, +run `git commit` to finally record the merge: + +------------ +$ git commit +------------ + +As with the case to record your own changes, you can use `-a` +option to save typing. One difference is that during a merge +resolution, you cannot use `git commit` with pathnames to +alter the order the changes are committed, because the merge +should be recorded as a single commit.
