git-describe: Create a name with 4 digits for the abbreviated commit hash.
$ git describe --abbrev=${4}
try on your machine
The command "git describe --abbrev=${4}" is used to provide a description of the current commit in a repository.
Here's an explanation of the command and its options:
- "git describe" is the base command to retrieve a description of a commit.
- "--abbrev=${4}" is an option where ${4} denotes a variable that specifies the desired abbreviation length for the commit ID in the description.
For instance, the command "git describe --abbrev=4" will generate a commit description using the most recent annotated tag reachable from the commit, followed by the number of additional commits on top of the annotated tag, and finally a partial SHA-1 commit ID. The abbreviation length for the partial SHA-1 commit ID will be 4 characters.
