newline

问题 How can I use bash command line to add new line character at the end of file named file.txt . I tried use echo but it's not right. Can you show me how can I do it? 回答1: echo "" >> file.txt Adds a newline character at the end 回答2: With sed : sed -i '' -e '$a\' file.txt with echo : echo >> file.txt 回答3: Use Vi which automatically creates EOL at EOF on file save. For example: vi -escwq foo.txt or: ex -scwq foo.txt To correct multiple files, check: How to fix 'No newline at end of file' for lots

问题 I am working with Notepad++ and I would like to find the new line (after the hyphen, optional space and some characters in the end line). I have came up with something like this : -[ ]?.*\n I have also tried : -[ ]?.*(\n) -[ ]?.*(\r\n) -[ ]?.*[\r\n] -[ ]?.*[\n] None of these worked. I am working on Windows if it matters. 回答1: Do you actually need to match the line break? If not, you can simply use $ which is the anchor for end of a line. 回答2: \R (capital R) will grab any end of line

问题 import logging logging.basicConfig(level=logging.DEBUG, format='%(asctime)s %(levelname)s %(message)s', datefmt='%H:%M:%S') logging.info('hello') logging.warning('\n new hello') 11:15:01 INFO hello 11:16:49 WARNING new hello Because the log is crowded, I want to explicitly insert a newline before asctime and levelname .

问题 I am trying to replace \n characters to new line of a data which comes from endpoint.

Output is like: {{ item.licensedocument.legal.documentText.replace(/(?:\r\n|\r|\n)/g, ' ') }} When I write just <p>{{ item.licensedocument.legal.documentText }}</p> it works and output is like

问题 This question already has answers here : How can I replace a newline (\n) using sed? (41 answers) Closed 4 years ago . Have output from sed : http://sitename.com/galleries/83450 72-profile Those two strings should be merged into one and separated with space like: http://sitename.com/galleries/83450 72-profile Two strings are pipelined to tr in order to replace newline with space: tr '\n' ' ' And it's not working, the result is the same as input.

问题 I have this simple code: string isNewline(string text) { string toReturn; text == "\r\n" ? toReturn = "(newline)" : toReturn = text; return toReturn; } this function never returns a "(newline)" string, so I'm guessing that my comparison with newline character is wrong. How can I correct this? PS. Windows function 回答1: There is nothing wrong with your isNewline function. The problem is how you get the string to be passed to isNewline function. I suspect you use something like getline(fin,aLine
