os/perm-string



    cfunction

    (os/perm-string int)

    Convert a Unix octal permission value from a permission integer as 
    returned by os/stat to a human readable string, that follows the 
    formatting of unix tools like ls. Returns the string as a 9 
    character string of r, w, x and - characters. Does not include the 
    file/directory/symlink character as rendered by `ls`.
