Note that: + + - the behaviour is slightly different from that of "/bin/ls" in that the + '<path>' denotes just a list of patterns to match, e.g. so specifying + directory name (without `-r`) will behave differently, and order of the + arguments does not matter. + + - the behaviour is similar to that of "/bin/ls" in that the '<path>' is + taken as relative to the current working directory. E.g. when you are + in a directory 'sub' that has a directory 'dir', you can run 'git + ls-tree -r HEAD dir' to list the contents of the tree (that is + `sub/dir` in `HEAD`). You don't want to give a tree that is not at the + root level (e.g. `git ls-tree -r HEAD:sub dir`) in this case, as that + would result in asking for `sub/sub/dir` in the `HEAD` commit. + However, the current working directory can be ignored by passing + --full-tree option. + +OPTIONS +------- +<tree-ish>:: + Id of a tree-ish. + +-d:: + Show only the named tree entry itself, not its children. + +-r:: + Recurse into sub-trees. + +-t:: + Show tree entries even when going to recurse them. Has no effect + if `-r` was not passed. `-d` implies `-t`. + +-l:: +--long:: + Show object size of blob (file) entries. + +-z:: + \0 line termination on output and do not quote filenames. + See OUTPUT FORMAT below for more information. + +--name-only:: +--name-status:: + List only filenames (instead of the "long" output), one per line. + Cannot be combined with `--object-only`. + +--object-only:: + List only names of the objects, one per line. Cannot be combined + with `--name-only` or `--name-status`. + This is equivalent to specifying `--format='%(objectname)'`, but + for both this option and that exact format the command takes a + hand-optimized codepath instead of going through the generic + formatting mechanism. + +--abbrev[=<n>]:: + Instead of showing the full 40-byte hexadecimal object + lines, show the shortest prefix that is at least '<n>' + hexdigits long that uniquely refers the object. + Non default number of digits can be specified with --abbrev=<n>. + +--full-name:: + Instead of showing the path names relative to the current working + directory, show the full path names. + +--full-tree:: + Do not limit the listing to the current working directory. + Implies --full-name. + +--format=<format>:: + A string that interpolates `%(fieldname)` from the result + being shown. It also interpolates `%%` to `%`, and + `%xx` where `xx` are hex digits interpolates to character + with hex code `xx`; for example `%00` interpolates to + `\0` (NUL), `%09` to `\t` (TAB) and `%0a` to `\n` (LF). + When specified, `--format` cannot be combined with other + format-altering options, including `--long`, `--name-only` + and `--object-only`. + +[<path>...]:: + When paths are given, show them (note that this isn't really raw + pathnames, but rather a list of patterns to match). Otherwise + implicitly uses the root level of the tree as the sole path argument. + + +Output Format +------------- + +The output format of `ls-tree` is determined by either the `--format` +option, or other format-altering options such as `--name-only` etc. +(see `--format` above). + +The use of certain `--format` directives is equivalent to using those +options, but invoking the full formatting machinery can be slower than +using an appropriate formatting option. + +In cases where the `--format` would exactly map to an existing option +`ls-tree` will use the appropriate faster path. Thus the default format +is equivalent to: + + %(objectmode) %(objecttype) %(objectname)%x09%(path) + +This output format is compatible with what `--index-info --stdin` of +'git update-index' expects. + +When the `-l` option is used, format changes to + + %(objectmode) %(objecttype) %(objectname) %(objectsize:padded)%x09%(path) + +Object size identified by <objectname> is given in bytes, and right-justified +with minimum width of 7 characters. Object size is given only for blobs +(file) entries; for other entries `-` character is used in place of size. + +Without the `-z` option, pathnames with "unusual" characters are +quoted as explained for the configuration variable `core.quotePath` +(see linkgit:git-config[1]). Using `-z` the filename is output +verbatim and the line is terminated by a NUL byte. + +Customized format: + +It is possible to print in a custom format by using the `--format` option, +which is able to interpolate different fields using a `%(fieldname)` notation. +For example, if you only care about the "objectname" and "path" fields, you +can execute with a specific "--format" like + + git ls-tree --format='%(objectname) %(path)' <tree-ish> + +FIELD NAMES +----------- + +Various values from structured fields can be used to interpolate +into the resulting output. For each outputing line, the following +names can be used: + +objectmode:: + The mode of the object. +objecttype:: + The type of the object (`commit`, `blob` or `tree`). +objectname:: + The name of the object. +objectsize[:padded]:: + The size of a `blob` object ("-" if it's a `commit` or `tree`). + It also supports a padded format of size with "%(objectsize:padded)". +path:: + The pathname of the object. + +GIT +--- +Part of the linkgit:git[1] suite |
