Subject: Re: check if file exists for part of the filename

[mailto:list-bounce@example.com] On Behalf Of Christian Kerth
# How do i check if a file exists, that starts with a certain 
# identifier?
# e.g. Files in Directory
# file_1.rb
# file_2.rb
# test_1.rb
# I only want to know if a file exists, that starts with "file_"

there are many ways. 
these are just some...

Dir.glob("file_*.rb").empty?
#=> false

Dir.glob("file_*.rb").size>0
#=> true

Dir.glob("file_*.rb")
#=> ["file_1.rb", "file_2.rb", "file_3.rb"]

File.exist? "file_1.rb"
#=> true

File.exist? "file_2.rb"
#=> true

File.exist? "file_4.rb"
#=> false
