Имя (Name)
git-symbolic-ref - Read, modify and delete symbolic refs
Синопсис (Synopsis)
git symbolic-ref [-m <reason>] <name> <ref>
git symbolic-ref [-q] [--short] <name>
git symbolic-ref --delete [-q] <name>
Описание (Description)
Given one argument, reads which branch head the given symbolic
ref refers to and outputs its path, relative to the .git/
directory. Typically you would give HEAD
as the <name> argument
to see which branch your working tree is on.
Given two arguments, creates or updates a symbolic ref <name> to
point at the given branch <ref>.
Given --delete
and an additional argument, deletes the given
symbolic ref.
A symbolic ref is a regular file that stores a string that begins
with ref: refs/
. For example, your .git/HEAD
is a regular file
whose contents is ref: refs/heads/master
.
Параметры (Options)
-d, --delete
Delete the symbolic ref <name>.
-q, --quiet
Do not issue an error message if the <name> is not a symbolic
ref but a detached HEAD; instead exit with non-zero status
silently.
--short
When showing the value of <name> as a symbolic ref, try to
shorten the value, e.g. from refs/heads/master
to master
.
-m
Update the reflog for <name> with <reason>. This is valid
only when creating or updating a symbolic ref.
Примечание (Note)
In the past, .git/HEAD
was a symbolic link pointing at
refs/heads/master
. When we wanted to switch to another branch, we
did ln -sf refs/heads/newbranch .git/HEAD
, and when we wanted to
find out which branch we are on, we did readlink .git/HEAD
. But
symbolic links are not entirely portable, so they are now
deprecated and symbolic refs (as described above) are used by
default.
git symbolic-ref will exit with status 0 if the contents of the
symbolic ref were printed correctly, with status 1 if the
requested name is not a symbolic ref, or 128 if another error
occurs.
