объедините две или более историй развития вместе (Join two or more development histories together)
Описание (Description)
Incorporates changes from the named commits (since the time their
histories diverged from the current branch) into the current
branch. This command is used by git pull to incorporate changes
from another repository and can be used by hand to merge changes
from one branch into another.
Assume the following history exists and the current branch is
"master":
A---B---C topic
/
D---E---F---G master
Then "git merge topic" will replay the changes made on the topic
branch since it diverged from master (i.e., E) until its current
commit (C) on top of master, and record the result in a new
commit along with the names of the two parent commits and a log
message from the user describing the changes.
A---B---C topic
/ \
D---E---F---G---H master
The second syntax ("git merge --abort") can only be run after the
merge has resulted in conflicts. git merge --abort will abort the
merge process and try to reconstruct the pre-merge state.
However, if there were uncommitted changes when the merge started
(and especially if those changes were further modified after the
merge was started), git merge --abort will in some cases be
unable to reconstruct the original (pre-merge) changes.
Therefore:
Warning: Running git merge with non-trivial uncommitted changes
is discouraged: while possible, it may leave you in a state that
is hard to back out of in the case of a conflict.
The third syntax ("git merge --continue") can only be run after
the merge has resulted in conflicts.
