git-ls-tree - Linux
Overview
git-ls-tree lists the contents of a tree object. A tree object stores a snapshot of the files and directories in a Git repository at a specific point in time. It is used to display the file structure and metadata of a specific commit, branch, or tag.
Syntax
git ls-tree [-d|-t|-f|-o] <tree-ish>
Options/Flags
- -d: Display only directories.
- -t: Display only tree objects.
- -f: Display files in tree objects even if they are not in the current working directory.
- -o: Display the object ID for each file or directory.
Examples
List the files and directories in the current commit:
git ls-tree HEAD
List only the directories in the current commit:
git ls-tree -d HEAD
List the file contents of a specific commit:
git ls-tree -f e5657629e0
Display the object ID for each file in the current commit:
git ls-tree -o HEAD
Common Issues
- Error: Cannot find the object: This error occurs when the specified tree-ish does not exist. Ensure that you have entered the correct object ID or reference.
- Empty output: The command may not produce any output if the tree is empty or if the specified options filter out all the content.
Integration
Combine with git diff
to compare file trees:
git diff --raw HEAD HEAD^ | git ls-tree -t -r
Use with git cat-file
to display file contents:
git cat-file -p $(git ls-tree -o -f HEAD^ file.txt)
