git-check-attr - Display gitattributes information

'git check-attr' [-a | --all | attr...] [--] pathname...
'git check-attr' --stdin [-z] [-a | --all | attr...] < <list-of-paths>

For every pathname, this command will list if each attribute is 'unspecified',
'set', or 'unset' as a gitattribute on that pathname.

-a, --all::
	List all attributes that are associated with the specified
	paths.  If this option is used, then 'unspecified' attributes
	will not be included in the output.

	Consider `.gitattributes` in the index only, ignoring the working tree.

	Read file names from stdin instead of from the command-line.

	The output format is modified to be machine-parseable.
	If `--stdin` is also given, input paths are separated
	with a NUL character instead of a linefeed character.

	Interpret all preceding arguments as attributes and all following
	arguments as path names.

If none of `--stdin`, `--all`, or `--` is used, the first argument
will be treated as an attribute and the rest of the arguments as


The output is of the form:
<path> COLON SP <attribute> COLON SP <info> LF

unless `-z` is in effect, in which case NUL is used as delimiter:
<path> NUL <attribute> NUL <info> NUL

<path> is the path of a file being queried, <attribute> is an attribute
being queried and <info> can be either:

'unspecified';; when the attribute is not defined for the path.
'unset';;	when the attribute is defined as false.
'set';;		when the attribute is defined as true.
<value>;;	when a value has been assigned to the attribute.

Buffering happens as documented under the `GIT_FLUSH` option in
linkgit:git[1].  The caller is responsible for avoiding deadlocks
caused by overfilling an input buffer or reading from an empty output


In the examples, the following '.gitattributes' file is used:
*.java diff=java -crlf myAttr !myAttr
README caveat=unspecified

* Listing a single attribute:
$ git check-attr diff org/example/
org/example/ diff: java

* Listing multiple attributes for a file:
$ git check-attr crlf diff myAttr -- org/example/
org/example/ crlf: unset
org/example/ diff: java
org/example/ myAttr: set

* Listing all attributes for a file:
$ git check-attr --all -- org/example/
org/example/ diff: java
org/example/ myAttr: set

* Listing an attribute for multiple files:
$ git check-attr myAttr -- org/example/ org/example/
org/example/ myAttr: set
org/example/ myAttr: unspecified

* Not all values are equally unambiguous:
$ git check-attr caveat README
README: caveat: unspecified
