6 git-check-attr - Display gitattributes information
12 'git check-attr' [-a | --all | <attr>...] [--] <pathname>...
13 'git check-attr' --stdin [-z] [-a | --all | <attr>...]
17 For every pathname, this command will list if each attribute is 'unspecified',
18 'set', or 'unset' as a gitattribute on that pathname.
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.
28 Consider `.gitattributes` in the index only, ignoring the working tree.
31 Read pathnames from the standard input, one per line,
32 instead of from the command-line.
35 The output format is modified to be machine-parsable.
36 If `--stdin` is also given, input paths are separated
37 with a NUL character instead of a linefeed character.
40 Interpret all preceding arguments as attributes and all following
41 arguments as path names.
43 If none of `--stdin`, `--all`, or `--` is used, the first argument
44 will be treated as an attribute and the rest of the arguments as
50 The output is of the form:
51 <path> COLON SP <attribute> COLON SP <info> LF
53 unless `-z` is in effect, in which case NUL is used as delimiter:
54 <path> NUL <attribute> NUL <info> NUL
57 <path> is the path of a file being queried, <attribute> is an attribute
58 being queried and <info> can be either:
60 'unspecified';; when the attribute is not defined for the path.
61 'unset';; when the attribute is defined as false.
62 'set';; when the attribute is defined as true.
63 <value>;; when a value has been assigned to the attribute.
65 Buffering happens as documented under the `GIT_FLUSH` option in
66 linkgit:git[1]. The caller is responsible for avoiding deadlocks
67 caused by overfilling an input buffer or reading from an empty output
73 In the examples, the following '.gitattributes' file is used:
75 *.java diff=java -crlf myAttr
77 README caveat=unspecified
80 * Listing a single attribute:
82 $ git check-attr diff org/example/MyClass.java
83 org/example/MyClass.java: diff: java
86 * Listing multiple attributes for a file:
88 $ git check-attr crlf diff myAttr -- org/example/MyClass.java
89 org/example/MyClass.java: crlf: unset
90 org/example/MyClass.java: diff: java
91 org/example/MyClass.java: myAttr: set
94 * Listing all attributes for a file:
96 $ git check-attr --all -- org/example/MyClass.java
97 org/example/MyClass.java: diff: java
98 org/example/MyClass.java: myAttr: set
101 * Listing an attribute for multiple files:
103 $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
104 org/example/MyClass.java: myAttr: set
105 org/example/NoMyAttr.java: myAttr: unspecified
108 * Not all values are equally unambiguous:
110 $ git check-attr caveat README
111 README: caveat: unspecified
116 linkgit:gitattributes[5].
