问题 I have a simple mongoDB query: var qry = QueryBuilder.start qry.and("website").exists(true) qry.and("website").notEquals(null) qry.and("_id").in(loc_ids) website is a field in my collection, and loc_ids are a list of OIDs to each record... The cursor does not result in any records returned from the query? Seems like the problem is the "website" : { "$exists" : true , "$ne" : ""}...

问题 I have the following query.explain(1)-Output. It is a verbose output and my question is how to read that. How is the order of the operations? Does it starts with GEO_NEAR_2DSPHERE or with LIMIT?

问题 In Linux how do I find all soft links that link to a specific target directory or file? 回答1: You could use find 's -lname argument: find . -lname linktarget 回答2: Use find with -samefile and -L option, like this: find -L -samefile TARGET 回答3: What R1tschY sez, with an addition: find -L -samefile TARGET \! -name TARGET so TARGET won't be included in the result. (The backslash is required in bash so the ! won't be interpreted as a history directive.) 来源： https://stackoverflow.com/questions

问题 My question is, how can I find all array indexes by a word ? [ {name: "Jeff Crawford", tel: "57285"}, {name: "Jeff Maier", tel: "52141"}, {name: "Tim Maier", tel: "73246"} ] If I search for "Jeff", I want to get: [ {name: "Jeff Crawford", tel: "57285"}, {name: "Jeff Maier", tel: "52141"}, ] 回答1: To make it more versatile, you could take a function which takes an array of objects, the wanted key and the search string, wich is later used as lower case string. function find(array, key, value) {

问题 My last question expanded, so let's analyse things separately. AND-operater, Intersection? I will give an example: $ find . | awk -F"/" '{ print $2 }' .zcompdump .zshrc .zshrc_copy .zshrc_somequy .bashrc .emacs $ find ~/bin/FilesDvorak/.* -maxdepth 0 | awk -F"/" '{ print $6 }' .bashrc .emacs .gdbinit .git .profile When I save the outputs to separate lists, I cannot understand why the command does not take the common things: find -f all_files -and -f right_files . I want only: .bashrc .emacs
