$fexist(<file>)
$fexist("" <file>)

• The <file> argument is a dword which is different from most function arguments.
• In the first case, <file> is a single extended word (you may surround it with double quotes if it contains spaces). Any further arguments are ignored.
• In the second case, the first argument is an empty string, and the rest of the arguments are taken as a filename literally. Do not backslash or double quote anything in <file>.
• Tilde-expansion is supported in both forms, both “~/file” for files in your home directory and “~user/file” for files in someone else's home directory.
• If <file> is not a symbolic link, it exists, and you have read access to it, the return value is 1.
• If <file> is a symbolic link and the file it points to exists, and you have read access to it, the return value is 1.
• In the other cases (the file doesn't exist, or you can't read it), the return value is -1.

This function is used when you want to see if a particular file exists. This could be useful to make sure a file is present before trying to load it. This function does not return 0!

-1   file does not exist or is not readable by you.
 1   file exists and you can read it.

$fexist(/etc/passwd)                   probably will return 1
$fexist(~/.ircrc)                      probably will return 1 too
$fexist(fake_file)                     returns -1
