line-numbers

问题 I want to delete one or more specific line numbers from a file. How would I do this using sed? 回答1: If you want to delete lines 5 through 10 and 12: sed -e '5,10d;12d' file This will print the results to the screen. If you want to save the results to the same file: sed -i.bak -e '5,10d;12d' file This will back the file up to file.bak , and delete the given lines. Note: Line numbers start at 1. The first line of the file is 1, not 0. 回答2: You can delete a particular single line with its line

问题 Using the XMLReader XML parser in PHP 5.3, I need to get the line number of the current node. A column number or total offset from the beginning of the file would be nice, too. Hopefully I don't have to use some hack like parsing every raw node string for newlines (with readOuterXML() ), but I don't see a getLineNo() property like in the DOM... 回答1: See XMLReader::expand which returns a DOMNode element, which in turn supports getLineNo() 来源： https://stackoverflow.com/questions/2530679/using

问题 I am trying to use hunspell to correct an essay i have written. Unfortunately it is useless to me, as long as it doesn't print the line number of the word, which it predicts to be misspelled.

But I don't see any difference in the output. This is what I do right now: cat myessay.txt | hunspell -d en_US,de_DE -a -L An example output looks

问题 I'm working on an 'IDE' for Android - it could be useful for editing short scripts / making quick adjustments to files. At the moment I'm just using a simple EditText, but I am wanting to add several features, for example Line Numbering down the left hand side of the EditText and Code Highlighting. Does anyone have any suggestions about how to approach this? For the code highlighting, I'm guessing I'll need to write my own subclass of EditText. For the line numbering, could I have a thin

问题 I know of an Eclipse feature to show revision information (gradual coloring, more info like revisionnumber, date and author on mouseover) for the last changes in a line in the linenumbers-view. Does anyone know how to activate this feature for a file, or even better, by default? I accidently hit some shortcut lately which made it show in one file, it does not show up in the others, though. 回答1: This is called "Show Annotation" and you can find it in the "Team" menu. Since this is a pretty

问题 I understand that I can get the current line number of a file I am looping through with the builtin variable $. . As an experiment, I used that to prefix each line in a file with the value of $. (the current line number). However, this did not work as expected. I.e. given the following file contents line one line two line three then I would expect the following code to prefix each line with its line number for my $line (<FILE>) { print "$. : $line"; } but, instead, it gives the following

问题 When I am looping over a file using the construct below, I also want the current line number. with codecs.open(filename, 'rb', 'utf8' ) as f: retval = [] for line in f: process(line) Does something akin to this exist ? for line, lineno in f: 回答1: for lineno, line in enumerate(f, start=1): If you are stuck on a version of Python that doesn't allow you to set the starting number for enumerate (this feature was added in Python 2.6), and you want to use this feature, the best solution is probably
