You could use a [negative look-ahead][1] assertion:

    ^(?!tbd_).+

Or a negative look-behind assertion:

    (^.{1,3}$|^.{4}(?&lt;!tbd_).*)

Or just plain old character sets and alternations:

    ^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

I&#39;m very new to HTML and CSS and I was just wondering how I could make my font bold using CSS.

I have a plain HTML page that imports a CSS file, and I can change the font in the CSS. But I don&#39;t know how to make the font bold, can anyone help me?

I would like to comment this with a line 

    {% if something.property %}
        &lt;table&gt;

    {% # this is a comment %}
    {% if something.property %}
        &lt;table&gt;
            &lt;tr&gt;...

I&#39;m processing a bunch of tables using [this program][1], but I need to ignore ones that start with the label &quot;tbd_&quot;. So far I have something like [^tbd_] but that simply not match those characters.

I need to do a regex find and replace on all the files in a folder (and its subfolders). What would be the linux shell command to do that?

For example, I want to run this over all the files and overwrite the old file with the new, replaced text.

    sed &#39;s/old text/new text/g&#39; 

Changing all occurrences in a folder

I&#39;m having a hard time finding a good resource that explains how to use Named Capturing Groups in C#.  This is the code that I have so far:

    string page = Encoding.ASCII.GetString(bytePage);
    Regex qariRegex = new Regex(&quot;&lt;td&gt;&lt;a href=\&quot;(?&lt;link&gt;.*?)\&quot;&gt;(?&lt;name&gt;.*?)&lt;/a&gt;&lt;/td&gt;&quot;);
    MatchCollection mc = qariRegex.Matches(page);
    CaptureCollection cc = mc[0].Captures;
    MessageBox.Show(cc[0].ToString());

However this always just shows the full line:

    &lt;td&gt;&lt;a href=&quot;/path/to/file&quot;&gt;Name of File&lt;/a&gt;&lt;/td&gt; 

I have experimented with several other &quot;methods&quot; that I&#39;ve found on various websites but I keep getting the same result.

How can I access the named capturing groups that are specified in my regex?

I am using `split()` to tokenize a String separated with `*` following this format:

    name*lastName*ID*school*age
    %
    name*lastName*ID*school*age
    %
    name*lastName*ID*school*age

I&#39;m reading this from a file named &quot;entrada.al&quot; using this code:

    static void leer() {
    
        try {
            String ruta=&quot;entrada.al&quot;;
            File myFile = new File (ruta);
            FileReader fileReader = new FileReader(myFile);
    
            BufferedReader reader = new BufferedReader(fileReader);
    
            String line = null;
    
            while ((line=reader.readLine())!=null){
                if (!(line.equals(&quot;%&quot;))){
                    String [] separado = line.split(&quot;*&quot;); //SPLIT CALL
                    names.add(separado[0]);
                    lastNames.add(separado[1]);
                    ids.add(separado[2]);
                    ages.add(separado[3]);
                }
            }
    
            reader.close();
        }

And I&#39;m getting this exception:  
&gt;Exception in thread &quot;main&quot; java.util.regex.PatternSyntaxException: Dangling meta character &#39;*&#39; near index 0
*

My guess is that the lack of a `*` after age on the original text file is causing this. How do I get around it?


Tokenizing Error: java.util.regex.PatternSyntaxException, dangling metacharacter &#39;*&#39;

I have a file that contains:

    something
    
    

    something else
    
    something else again

I need a bash command, sed/grep w.e that will produce the following output

    something
    
    something else
    
    something else again

In other words, I need to replace multiple blank lines with just a single blank line. grep/sed are line based. I&#39;ve never found a BASH solution that would work on multi-line regex patterns.

How can I replace multiple empty lines with a single empty line in bash?

I want a regex that matches a square bracket `[`. I haven&#39;t found one yet. I think I tried all possibilities, but haven&#39;t found the right one. What is a valid regex for this?
