I'm trying to use ioutils.WriteFile() but for some reason it's ignoring the 0777 permissions I'm giving it.
package main
import (
"io/ioutil"
"os"
)
func main() {
// normal permissions
if err := ioutil.WriteFile("cant-touch-this-0644", []byte{}, 0644); err != nil {
panic(err)
}
// full permissions
if err := ioutil.WriteFile("cant-touch-this-0777", []byte{}, 0777); err != nil {
panic(err)
}
// normal permissions + chmod to full
if err := ioutil.WriteFile("cant-touch-this-mixed", []byte{}, 0755); err != nil {
panic(err)
}
if err := os.Chmod("cant-touch-this-mixed", 0777); err != nil {
panic(err)
}
}
The output I get from this is:
$ ls -l
-rw-r--r-- 1 edson edson 0 May 9 17:19 cant-touch-this-0644
-rwxr-xr-x 1 edson edson 0 May 9 17:19 cant-touch-this-0777
-rwxrwxrwx 1 edson edson 0 May 9 17:19 cant-touch-this-mixed
Which means:
- The first scenario (0644) worked
- The second (0777) was ignored
- The only way I can get full 0777 permissions is by using a
os.Chmod
(like in the third scenario)
What am I doing wrong?
