Ruby extension to get mount information in Linux

ruby-talk
1

Is there a library for getting information in drives that can be mounted and
can then mount or unmount those drives in Linux/Unix, I can write my
program to read the /etc/fstab file but then I would have to go to extra
trouble to find out if the drives are mounted or not so I would preffer
having a library to do the work for me.

I’m not getting any replies so I’ll try explaining what I am asking again in
case the silence is related to people not understanding what I was asking.

Basically what I would like to know is if there is a ruby library or
extension for the mount command in Linux, I also need it to be able to get
information on the drives that can be mounted.

See what happens if you search the Ruby Application Archive
(http://raa.ruby-lang.org) for the keyword “mount”.

/etc/fstab are the drives that can be mounted

/etc/mtab are the drives that ARE mounted.

I found something that I think will tell me if a certain folder is a mounted
device, but there was nothing there for extracting the information from
/etc/fstab , I’d write something for it myself but I am a newbie at Ruby
and I’ve only read tutorials so far os I don’t know much yet. I find it
easier to learn from books, its much easier to read when the text is on
paper rather then on a monitor.

If you search the RAA for the keyword “mount”, one of the few matches is
for the “FileSystem” extension:

http://raa.ruby-lang.org/list.rhtml?name=filesystem

If you download, build and install this extension, you can then write a
little script like this one to extract information from /etc/fstab:

 require 'filesystem'

 FileSystem.mounts("/etc/fstab") { |m|
   puts m.device
   puts m.mount
   puts m.fstype
   puts m.options
   puts m.dump_interval
   puts m.check_pass
   puts "----------------------"
 }
