linux - How to find a text string within a config file and add two new lines below with one single line command? -

-

I'm trying to fight that pedal SSL bug and I have to change a lot of configuration files.

I try to save myself some work and this is done by a single line command, thus I need to modify - for example - /etc/lighttpd/lighttpd.conf.

I am looking for ssl.engine = "enable"

and I want to add two new lines found with the following string: 

  Ssl.use-sslv2 = "disable" ssl.use-sslv3 = "disable"

The end result should be: 

  $ server [ "Socket"] == "0.0.0.0:80" {ssl.engine = "enabled" ssl.use-sslv2 = "disabled" ssl.use-SSLv3 = "disable" ssl.pemfile = "/ etc / ssl / Cert.pem "ssl.ca- file =" /etc/ssl/cert.bundle "}

I tried with the AWC but I used to work due to spaces and carriage returnsNew it can not achieve.

Someone is happy to see a liner :)

Here is what I have tried (of course something wrong here): 

 < Code> awk '{a [NR] = $ 0} /ssl.engine/ {a [NR + 1] = a [nr + 1] "ssl.use-sslv2 =" disable ""} {single . + 2] "ssl.use-SSLv3 =" disabled ""} {For the end (i = 1; i  

  awk '{print} /ssl\.engine = "ext" itemprop = "enable text" / {print} ssl.use-sslv2 = \ "disabled \" \ nssl.use-sslv3 = \ "Disable \" "} 'file

Note that'. 'Is an RE Metacrector, so it needs to be re-saved in context.

If you use the original file Want to modify GNU with one: 

  awk -i inplace '...' file

and any awk or any other Unix device With: 

  awk '...' file & gt; Tmp & Mv tmp file

explicitly: 

  awk -i inplace '{print} /ssl\.engine = "enable" / {print "ssl.use -sslv2 = \" disable \ "\ nssl.use-sslv3 = \" disable \ ""} File awk "{print} /ssl\.engine =" enable "/ {print" ssl.use-sslv2 = \ "disable \" \ nssl.use-sslv3 = \ "disable \" "} 'File & gt; TMP & amp; Mv tmp file

winforms - C# Form - Property Change -

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
