Output Format
-------------
- <mode> SP <type> SP <object> TAB <file>
+
+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
- <mode> SP <type> SP <object> SP <object size> TAB <file>
+ %(objectmode) %(objecttype) %(objectname) %(objectsize:padded)%x09%(path)
-Object size identified by <object> is given in bytes, and right-justified
+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.
@@ -100,6 +132,34 @@ 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 (`blob` or `tree`).
+objectname::
+ The name of the object.
+objectsize[:padded]::
+ The size of the object ("-" if it's a tree).
+ It also supports a padded format of size with "%(size:padded)".
+path::
+ The pathname of the object.
