# git-check-attr(1) Manual Page

## NAME

git-check-attr - Display gitattributes information

## SYNOPSIS

    git check-attr [--source <tree-ish>] [-a | --all | <attr>…​] [--] <pathname>…​
    git check-attr --stdin [-z] [--source <tree-ish>] [-a | --all | <attr>…​]

## DESCRIPTION

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

## OPTIONS

-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.

--cached

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

--stdin

  Read pathnames from the standard input, one per line, instead of from the command line.

-z

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

--source=<tree-ish>

  Check attributes against the specified tree-ish. It is common to specify the source tree by naming a commit, branch, or tag associated with it.

--

  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 pathnames.

## OUTPUT

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 git(1). The caller is responsible for avoiding deadlocks caused by overfilling an input buffer or reading from an empty output buffer.

## EXAMPLES

In the examples, the following .gitattributes file is used:

    *.java diff=java -crlf myAttr
    NoMyAttr.java !myAttr
    README caveat=unspecified

- Listing a single attribute:

      $ git check-attr diff org/example/MyClass.java
      org/example/MyClass.java: diff: java

- Listing multiple attributes for a file:

      $ git check-attr crlf diff myAttr -- org/example/MyClass.java
      org/example/MyClass.java: crlf: unset
      org/example/MyClass.java: diff: java
      org/example/MyClass.java: myAttr: set

- Listing all attributes for a file:

      $ git check-attr --all -- org/example/MyClass.java
      org/example/MyClass.java: diff: java
      org/example/MyClass.java: myAttr: set

- Listing an attribute for multiple files:

      $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
      org/example/MyClass.java: myAttr: set
      org/example/NoMyAttr.java: myAttr: unspecified

- Not all values are equally unambiguous:

      $ git check-attr caveat README
      README: caveat: unspecified
