find

问题 Batch file to search every single subfolder and every single file inside a directory and count the number of times a particular string is present in each file. Would be useful if output is "filename - count". Can do find /c "Microsoft" *.txt This works if all the files are in one folder. How do you make the find loop through all the subfolders and each of its files and display the same result. Findstr has /s which does that, doesnt work on find. 回答1: From command line: for /F "delims=" %G in

问题 I am trying to find all <h2> tags the split them and join them with <a href=''></a> around them. I am so close but stuck. <script type="application/javascript"> $(document).ready(function() { // finds all h2's within wrapper div grabs the text splits at ? and applies a links around each one var al = $('#wrapper').find('h2').text().split("?").join("?</a><br /> <a href='#'>"); // Add all the split h2's from the variable above al to a div called .text $('.text').html('<ul>' + al + '</ul>'); });

问题 There is the following example code in the BOOST MPL documentation of the find algorithm: typedef vector<char,int,unsigned,long,unsigned long> types; typedef find<types,unsigned>::type iter; ... BOOST_MPL_ASSERT_RELATION( iter::pos::value, ==, 2 ); However, I cannot find the documentation for the iterator's pos metafunction. Can I use it reliably? I'd like to use it somehow as: typedef vector<type1, type2, type3> types; template <typename T> void File::write(T value) { BOOST_MPL_ASSERT(

问题 I have two files tmp1.txt and tmp2.txt tmp1.txt has aaa.txt bbb.txt ccc.txt ddd.txt tmp2.txt has /tmp/test1/aaa.txt /tmp/test1/aac.txt /tmp/test2/bbb.txt /tmp/test1/ccc.txt I want to check if the files in tmp1.txt exists in tmp2.txt and if it exists display which one it has so it displays something similar to this aaa.txt: test1 bbb.txt: test2 ccc.txt: test1 Thanks 回答1: Using awk : awk -F/ 'FNR==NR {a[$1];next} $NF in a {print $NF ": " $(NF-1)}' tmp1.txt tmp2.txt aaa.txt: test1 bbb.txt: test2

问题 I have a plan to use find to give me a list of files that are older than some FILE and then use xargs (or -exec ) to move the files to somewhere else. Moving stuff is not a problem; | xargs mv {} ~/trash works fine. Now, if I try to use ! -newer FILE , then FILE is included in the list, which I do not want! The functionality of that command argument does indeed make sense logically, though, because 'not newer' could very well be interpreted as "same or older", like here: $ find . ! -newer

Closed 5 years ago . I am trying to find the coordinates of all non zero elements in a matrix, in MATLAB. I know that find makes this very easy. The problem is that I need to define the length of my matrix before I can fill it up. I believe this is impossible using find , since it will make its own vector. So I have to
