Ruby file is directory

Returns true if the named file is readable by the effective user and group id of this process. Returns true if the named file is readable by the real user and group id of this process. Returns the real absolute pathname of pathname in the actual filesystem. The real pathname doesn't contain symlinks or useless dots. Returns the real absolute pathname of pathname in the actual filesystem not containing symlinks or useless dots.

Renames the given file to the new name. Raises a SystemCallError if the file cannot be renamed. Splits the given string into a directory and a file component and returns them in a two-element array. See also ::dirname and ::basename. Returns a File::Stat object for the named file see File::Stat.

Raises a NotImplemented exception on platforms that do not support symbolic links. Returns the current umask value for this process.

If the optional argument is given, set the umask to that value and return the previous value. Umask values are subtracted from the default permissions, so a umask of would make a file read-only for everyone. If a file is a symlink, this method acts upon its referent rather than the link itself; for the inverse behavior see ::lutime. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat 2. Returns true if the named file is writable by the effective user and group id of this process.

Returns true if the named file is writable by the real user and group id of this process. Returns the last access time a Time object for file , or epoch if file has not been accessed.

If the platform doesn't have birthtime, raises NotImplementedError. Actual effects are platform dependent; on Unix systems, see chmod 2 for details. Follows symbolic links. Also see File lchmod. Changes the owner and group of file to the given numeric owner and group id's.

See also File lchown. Returns the change time for file that is, the time directory information about the file was changed, not the file itself. Same as IO stat , but does not follow the last symbolic link. The pathname may not point to the file corresponding to file. For instance, the pathname becomes void when the file has been moved or deleted. Truncates file to at most integer bytes. The file must be opened for writing. Home Core 2. Home Classes Methods. In Files dir.

Emily Emily Why bother even putting it inside another method? Just call it directly! Radar I figured that the stripped-down method was likely simplified for the purpose of the question and that the actual method might contain some additional logic.

If no other logic needs to go in the method, I agree. By all means, just run directory? Wouldn't Dir. Make sure you expand the relative path before checking: File.

However, there is one difference in between File.

The difference is that the File. Read-only mode. The file pointer is placed at the beginning of the file. This is the default mode. Write-only mode. Overwrites the file if the file exists. If the file does not exist, creates a new file for writing. Read-write mode.

Overwrites the existing file if the file exists. If the file does not exist, creates a new file for reading and writing. The file pointer is at the end of the file if the file exists.

That is, the file is in the append mode. If the file does not exist, it creates a new file for writing. Read and write mode. See the example on the doc page. If you want to continue using globbing this will give you a starting place.

You can put multiple tests in reject or'd together:. There's FileList from the Rake gem which is almost always installed by default, and is included in the standard library in Ruby 1.
