25.6 Information about Files

The functions described in this section all operate on strings that designate file names. All the functions have names that begin with the word `file'. These functions all return information about actual files or directories, so their arguments must all exist as actual files or directories unless otherwise noted.

25.6.1 Testing Accessibility  Is a given file readable? Writable?
25.6.2 Distinguishing Kinds of Files  Is it a directory? A symbolic link?
25.6.3 Truenames  Eliminating symbolic links from a file name.
25.6.4 Other Information about Files  How large is it? Any other names? Etc.
