6 git-check-attr - Display gitattributes information
12 'git check-attr' [-a | --all | attr...] [--] pathname...
13 'git check-attr' --stdin [-z] [-a | --all | attr...] < <list-of-paths>
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 file names from stdin instead of from the command-line.
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.
39 Interpret all preceding arguments as attributes and all following
40 arguments as path names.
42 If none of `--stdin`, `--all`, or `--` is used, the first argument
43 will be treated as an attribute and the rest of the arguments as
49 The output is of the form:
50 <path> COLON SP <attribute> COLON SP <info> LF
52 unless `-z` is in effect, in which case NUL is used as delimiter:
53 <path> NUL <attribute> NUL <info> NUL
56 <path> is the path of a file being queried, <attribute> is an attribute
57 being queried and <info> can be either:
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.
64 Buffering happens as documented under the `GIT_FLUSH` option in
65 linkgit:git[1]. The caller is responsible for avoiding deadlocks
66 caused by overfilling an input buffer or reading from an empty output
72 In the examples, the following '.gitattributes' file is used:
74 *.java diff=java -crlf myAttr
76 README caveat=unspecified
79 * Listing a single attribute:
81 $ git check-attr diff org/example/MyClass.java
82 org/example/MyClass.java: diff: java
85 * Listing multiple attributes for a file:
87 $ git check-attr crlf diff myAttr -- org/example/MyClass.java
88 org/example/MyClass.java: crlf: unset
89 org/example/MyClass.java: diff: java
90 org/example/MyClass.java: myAttr: set
93 * Listing all attributes for a file:
95 $ git check-attr --all -- org/example/MyClass.java
96 org/example/MyClass.java: diff: java
97 org/example/MyClass.java: myAttr: set
100 * Listing an attribute for multiple files:
102 $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
103 org/example/MyClass.java: myAttr: set
104 org/example/NoMyAttr.java: myAttr: unspecified
107 * Not all values are equally unambiguous:
109 $ git check-attr caveat README
110 README: caveat: unspecified
