xattr
|
||||
=====
|
||||
Extended attribute support for Go (linux + darwin + freebsd).
|
||||
|
||||
"Extended attributes are name:value pairs associated permanently with files and directories, similar to the environment strings associated with a process. An attribute may be defined or undefined. If it is defined, its value may be empty or non-empty." [See more...](https://en.wikipedia.org/wiki/Extended_file_attributes)
|
||||
|
||||
|
||||
### Example
|
||||
```
|
||||
const path = "/tmp/myfile"
|
||||
const prefix = "user."
|
||||
|
||||
if err = Setxattr(path, prefix+"test", []byte("test-attr-value")); err != nil {
|
||||
t.Fatal(err)
|
||||
}
|
||||
|
||||
var data []byte
|
||||
data, err = Getxattr(path, prefix+"test"); err != nil {
|
||||
t.Fatal(err)
|
||||
}
|
||||
```
