shell - Escape character confusing in sed command -


A common use that is to avoid sed 's / \\\. / \\\\\\\. ./g '
I completely confuse why so many \

/ \\\. /

Search for patterns.

By default, the following is the escape sequence and dot means "any four", so \. Escape slash (\\) is translated into resume format, followed by escape dot (\.)

/ \\\\\\\. Instead of ./

\\ 8 slash and 1 dot I 4 were already escaped from the slash for the same reason for the research pattern but the dot in the replacement pattern was mean dot Therefore there is no need to avoid it.

Another way to write it is to / [\] [.] / \\ \\\\ & amp; / for fun or / \ ([\] \) [.] / \ 1 \ 1 \ 1 & amp; / LE

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
