'update-grub' syntax error

Question

I have read and researched this throughout the internet and hoping now someone can help me through this. I am writing to read three different text files with different names, but I need to read through the text file name in order to determine which method I have to execute for that particular file. This is what I have so far, any help would be greatly appreciated.

var readers = new List<StreamReader>();

foreach (var filename in names_of_files)
{
    if (do something?)
    {
        switch
    }
}

using (StreamReader file = new StreamReader(filename))
{
  (reads the file and does other stuff)
}

Below is the method that I am using to select multiple files.

private void LoadNewFile()
{
    OpenFileDialog ofd = new OpenFileDialog();
    ofd.Multiselect = true;
    System.Windows.Forms.DialogResult dr = ofd.ShowDialog();
    ofd.Filter = "Text Files(*.txt) | *.txt";

    foreach (String file in ofd.FileNames)
    {
        if (dr == DialogResult.OK)
        {
            userSelectedFilePath += file;
            names_of_files.Add(userSelectedFilePath);
        }
    }
}

I just checked my /etc/default/grub and it looks the same as in your pastebin, but I also get this warning since the default-installation of Ubuntu 14.04 Trusty Thar.

So this does not help for me. The result is still the same. And I found that there is a big discussion already there on launchpad. Just look here:

https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1258597

But the comment #10 on this link shows the trick, how to sort things out. The file /etc/default/grub needs to be edited at the second line and at the third line as shown on the comment #10 on this above link of launchpad:

sudo gedit /etc/default/grub
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=countdown
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=1"
GRUB_CMDLINE_LINUX=""

Then do:

sudo update-grub

This sorts things out...

Grub Customizer adds or edits files in /etc/default/grub.d so the file you need to fix is in this directory, which is why there is nothing wrong with your /etc/default/grub file.

Additionally, the error tells you to inspect line 165 and the file you need to inspect is /boot/grub/grub.cfg.new.

So, go to the file /boot/grub/grub.cfg.new and scroll down to line number 165. This is where the syntax error is. At the beginning of each section of code, there is a line that starts with ### BEGIN followed by a configuration file name. This is the file that contains the error you need to fix.

See this detailed example by user @donquixote.

Solution 3

I have saved an original /etc/default/grub file in my pastebin for such situations. Open a terminal and do

sudo cp /etc/default/grub ~/default-grub.bad
sudo wget "http://pastebin.com/raw.php?i=g3TMZgTP" -o /etc/default/grub 
sudo update-grub 

See the file in raw format here

Additional suggestion:

You have a bunch of kernels installed. Try to remove the old ones. You can use a program such as ubuntu-tweak or synaptic.

I had a similar problem that I resolved it just deleting a menu I had in Grub Customizer. After removing this menu, Grub Customizer has started to save again without problems.

your question is similar to - askubuntu.com/questions/594924/…) .so it could solve your problem.

It is not clear what you want. If you need to do something different depending on file name then in your foreach you could do something like if (filename == "first name") DoFirstThing() ; else if (filename == "second name") DoSecondThing();.

Grub Customizer edits or creates files in your /etc/default/grub.d directory which is why there is nothing wrong with your /etc/default/grub file.

What if the file names are different everytime?

[GantTheWanderer]

You explained in the question "I need to read through the text file name in order to determine which method I have to execute for that particular file." What is it about the file name that allows you determine what to do with it? And what are you trying to acheive?

[SmartDeveloper]

I have three different types of files with three different names(new file for everyday with date), I need to run through each file. I was able to use the contains but now getting "The given paths format is not supported".

[GantTheWanderer]

Can you provide the name of the file when that error happens?
