Stripping the extensions off of a file

Ruby
1

I’m building a program that goes thru a file structure, and it will find
the longest filename and biggest files.

Find.find(directory) do |f|
file_sizes[File.size(f)]= f
if File.file?(f)
file_stripper = File.basename(f).delete(".jpg") #FIGURE OUT TO
STRIP THE ExTENSION

     file_length[f] = file_stripper
 end

end

I got that part, but I can’t seem to be able to strip the extension,
because I don’t want to count the extensions part part of the length.

Can the delete method take regexep? WHat would the regexep for something
like anything after the “.”?

thanks!

Find.find(directory) do |f|

file_sizes[File.size(f)]= f

if File.file?(f)

file_stripper = File.basename(f).delete(“.jpg”)

#FIGURE OUT TO

STRIP THE ExTENSION

get the extension, then pass it to #basename

botp@pc4all:~$ qri File.basename
--------------------------------------------------------- File::basename
File.basename(file_name [, suffix] ) → base_name

 Returns the last component of the filename given in file_name,
 which must be formed using forward slashes (``/'') regardless of
 the separator used on the local file system. If suffix is given
 and present at the end of file_name, it is removed.

    File.basename("/home/gumby/work/ruby.rb")          #=> "ruby.rb"
    File.basename("/home/gumby/work/ruby.rb", ".rb")   #=> "ruby"

:~$ irb
~001:0> name=“/home/botp/test.rb”
=> “/home/botp/test.rb”
~002:0> File.basename(name,File.extname(name))
=> “test”

kind regards -botp

great thanks! I didn’t know the File library had that method.
