   4NAME
   5----
   6git-check-attr - Display gitattributes information
   7
   8
   9SYNOPSIS
  10--------
  11[verse]
  12'git check-attr' [-a | --all | attr...] [--] pathname...
  13'git check-attr' --stdin [-z] [-a | --all | attr...] < <list-of-paths>
  14
  15DESCRIPTION
  16-----------
  17For every pathname, this command will list if each attribute is 'unspecified',
  18'set', or 'unset' as a gitattribute on that pathname.
  19
  20OPTIONS
  21-------
  22-a, --all::
  23        List all attributes that are associated with the specified
  24        paths.  If this option is used, then 'unspecified' attributes
  25        will not be included in the output.
  26
  27--cached::
  28        Consider `.gitattributes` in the index only, ignoring the working tree.
  29
  30--stdin::
  31        Read file names from stdin instead of from the command-line.
  32
  33-z::
  34        The output format is modified to be machine-parseable.
  35        If `--stdin` is also given, input paths are separated
  36        with a NUL character instead of a linefeed character.
  37
  38\--::
  39        Interpret all preceding arguments as attributes and all following
  40        arguments as path names.
  41
  42If none of `--stdin`, `--all`, or `--` is used, the first argument
  43will be treated as an attribute and the rest of the arguments as
  44pathnames.
  45
  46OUTPUT
  47------
  48
  49The output is of the form:
  50<path> COLON SP <attribute> COLON SP <info> LF
  51
  52unless `-z` is in effect, in which case NUL is used as delimiter:
  53<path> NUL <attribute> NUL <info> NUL
  54
  55
  56<path> is the path of a file being queried, <attribute> is an attribute
  57being queried and <info> can be either:
  58
  59'unspecified';; when the attribute is not defined for the path.
  60'unset';;       when the attribute is defined as false.
  61'set';;         when the attribute is defined as true.
  62<value>;;       when a value has been assigned to the attribute.
  63
  64Buffering happens as documented under the `GIT_FLUSH` option in
  65linkgit:git[1].  The caller is responsible for avoiding deadlocks
  66caused by overfilling an input buffer or reading from an empty output
  67buffer.

  69EXAMPLES
  70--------
  71
  72In the examples, the following '.gitattributes' file is used:
  73---------------
  74*.java diff=java -crlf myAttr
  75NoMyAttr.java !myAttr
  76README caveat=unspecified
  77---------------
  78
  79* Listing a single attribute:
  80---------------
  81$ git check-attr diff org/example/MyClass.java
  82org/example/MyClass.java: diff: java
  83---------------
  84
  85* Listing multiple attributes for a file:
  86---------------
  87$ git check-attr crlf diff myAttr -- org/example/MyClass.java
  88org/example/MyClass.java: crlf: unset
  89org/example/MyClass.java: diff: java
  90org/example/MyClass.java: myAttr: set
  91---------------
  92
  93* Listing all attributes for a file:
  94---------------
  95$ git check-attr --all -- org/example/MyClass.java
  96org/example/MyClass.java: diff: java
  97org/example/MyClass.java: myAttr: set
  98---------------
  99
 100* Listing an attribute for multiple files:
 101---------------
 102$ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
 103org/example/MyClass.java: myAttr: set
 104org/example/NoMyAttr.java: myAttr: unspecified
 105---------------
 106
 107* Not all values are equally unambiguous:
 108---------------
 109$ git check-attr caveat README
 110README: caveat: unspecified
 111---------------
