Basic file deleting question

Eric-

Thanks, but could you elaborate? How would you rewrite your line:

File.delete(Dir[""])

to specify deleting all files in the directory “output”.

Thanks!

What Ruby command will delete all files within a directory. (I’m using Ruby on Windows.)

I’m trying to delete all files within the directory “output”, which is itself in the current directory.

I’ve tried various lines looking like this:

File.delete(“./output/*”)

But I keep getting “Invalid arguement” or “permission denied” errors.

[22:10] drbrain@asx:~/ruby/tmp$ touch one two
[22:10] drbrain@asx:~/ruby/tmp$ ls
one two
[22:10] drbrain@asx:~/ruby/tmp$ ruby -e ‘File.delete(“one”, “two”)’
[22:10] drbrain@asx:~/ruby/tmp$ ls
[22:11] drbrain@asx:~/ruby/tmp$ touch one two
[22:10] drbrain@asx:~/ruby/tmp$ ls
one two
[22:11] drbrain@asx:~/ruby/tmp$ ruby -e ‘File.delete(Dir[""])’
[22:12] drbrain@asx:~/ruby/tmp$ ls
[22:12] drbrain@asx:~/ruby/tmp$

You’d want to cwd to the dir first:

Dir.chdir(‘output’)
File.delete(Dir[""])
