newline

问题 This question already has answers here : 'echo' without newline in a shell script (8 answers) Closed 2 years ago . Why doesn't $echo '-n' write -n on terminal although -n is written within single quotes ? 回答1: Because the quotes are processed by the shell and the echo command receives plain -n . If you want to echo -n , you can e.g. printf '%s\n' -n 回答2: you should try to use the more portable printf as far as possible. 回答3: You could try echo -e '\055n' 回答4: I found that the following just

问题 Suppose you have this text: name1 = "John"; age1 = 41; name2 = "Jane"; age2 = 32; name3 = "Mike"; age3 = 36; ... and you want to split each line into two lines to give a result like this: name1 = "John"; age1 = 41; name2 = "Jane"; age2 = 32; name3 = "Mike"; age3 = 36; ... How would you automate this operation? Some notes: I already tried the following method: (1) Select the text in virtual-vode, (2) Execute :'<,'>:norm ^3f r^M ***, but it doesn't work correctly; it splits only half of the

问题 How do you insert a string containing new lines into a TextBox?

If you already

Desired output: >> Correct! 回答1: Use blessings: from blessings import Terminal term = Terminal() raw_input("Question: ") print(term.move

问题 By the tutorials that I have seen. I learned how to add text on generating a docx file. but then Every time I add a line of text. I noticed that there is always a space between the first line of text and the second line of text. just like hitting the enter key twice. I know that the main cause is that everytime I add a line of text, I use a paragraph. and a paragraph starts with a space after another paragraph. This is how I add a text ObjectFactory factory; factory = Context

问题 How can I add newlines to a Label 's Text at design time? There are some posts on Stack Overflow on how to do this in code-behind, but there is no post about that for design time yet, it seems? 回答1: When you click on the label Text property in the Property window for the label, a drop down will appear in which you can, when you press Enter , go to the new line.

问题 I've got a git alias for a log using the pretty format: lg = log -10 --graph --abbrev-commit --pretty=format:'%C(auto)%d%Creset%n %C(bold yellow)%h%Creset - %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' Which gives the following: I can't seem to find a way to make a new line after the reference names only if the placeholder is non-empty. The pretty formats wiki page has operators to add or remove (+ or -) the newline coming before the placeholder but not after. 回答1: This is not supported

问题 A fellow coder uses a Windows computer that is putting carriage returns everywhere in our source. Is there a way to write a git hook that converts all \r\n to \n ? Note I haven't used git hooks before, so a little extra hand-holding might go a long way :) 回答1: The simplest thing is to set core.autocrlf to false on The Windows side. (that way Git won't do any conversion and will keep the eol untouched). On the unix side, a core.autocrlf set to true could help restore the proper eol. As
