strip

I wonder what is the difference between these two: gcc -s : Remove all symbol table and relocation information from the executable. strip : Discard symbols from object files. Do they have the same meaning? Which one do you use to: reduce the size of executable? speed up its running? Cascabel gcc being a compiler/linker, its -s option is something done while linking . It's also not configurable - it has a set of information which it removes, no more no less. strip is something which can be run on an object file which is already compiled. It also has a variety of command-line options which you

This question already has an answer here: rstrip not removing newline char what am I doing wrong? [duplicate] 3 answers This is my problem. I'm trying to read a text file and then convert the lines into floats. The text file has \n and \t in it though I don't know how to get rid of it. I tried using line.strip() but it didn't take it off and I got an error when I wanted to convert the stuff to floats. I then tried line.strip("\n") but that didn't work either. My program works fine when I take out the \t and \n from the text file, but it's part of the assignment to get it to work with them. I

This question already has an answer here: Trim string in JavaScript? 25 answers What's a clean and efficient JavaScript implementation to strip leading and trailing spaces from a string? For example: " dog" "dog " " dog " " dog " all get turned into "dog" David Andres Use this: if(typeof(String.prototype.trim) === "undefined") { String.prototype.trim = function() { return String(this).replace(/^\s+|\s+$/g, ''); }; } The trim function will now be available as a first-class function on your strings. For example: " dog".trim() === "dog" //true EDIT : Took J-P's suggestion to combine the regex

I'm using DOM to parse string. I need function that strips span tags and its contents. For example, if I have: This is some text that contains photo. <span class='title'> photobyile</span> I would like function to return This is some text that contains photo. This is what I tried: $dom = new domDocument; $dom->loadHTML($string); $dom->preserveWhiteSpace = false; $spans = $dom->getElementsByTagName('span'); foreach($spans as $span) { $naslov = $span->nodeValue; echo $naslov; $string = preg_replace("/$naslov/", " ", $string); } I'm aware that $span->nodeValue returns value of span tag and not

I have a Vim autocmd that removes trailing whitespace in files before write. I want this almost 100% of the time, but there are a few filetypes that I'd like it disabled. Conventional wisdom is to list the filetypes you want an autocmd to run against in a comma-separated list, eg: autocmd BufWritePre *.rb, *.js, *.pl But in this case that would be onerous. Is there a way to match an autocmd pattern against all files EXCEPT those matching the pattern? I cannot find the equivalent to a NOT matcher in the docs. *.rb isn't a filetype. It's a file pattern. ruby is the filetype and could even be set

find . -type f -print prints out ./file1 ./file2 ./file3 Any way to make it print file1 file2 file3 ? If they're only in the current directory find * -type f -print Is that what you want? Ilia K. Find only regular files under current directory, and print them without " ./ " prefix: find -type f -printf '%P\n' From man find, description of -printf format: %P File's name with the name of the command line argument under which it was found removed. Use sed find . | sed "s|^\./||" it can be shorter find * -type f 来源： https://stackoverflow.com/questions/2596462/how-to-strip-leading-in-unix-find
