Описание тега git-show

Shows one or more objects (blobs, trees, tags and commits).

• For commits it shows the log message and textual diff. It also presents the merge commit in a special format as produced by git diff-tree --cc.

• For tags, it shows the tag message and the referenced objects.

• For trees, it shows the names (equivalent to git ls-tree with--name-only).

• For plain blobs, it shows the plain contents.

The command takes options applicable to the git diff-tree command to control how the changes the commit introduces are shown.

See the man page for more info.
