find

问题 The command find /i "constructiontime" file.cfg outputs the line constructiontime(10); I want to read in this line and get just the number assigned to a variable independent on what is the number value. How can this be done? 回答1: The solution is using command FOR : @echo off set "ConstrutionTime=" for /F "tokens=2 delims=()" %%I in ('%SystemRoot%\System32\find.exe /I "constructiontime" file.cfg') do set "ConstrutionTime=%%I" if defined ConstrutionTime echo The construction time is:

问题 I would want to search up, down, and match case if possible. Even links to get me started would be appreciated. 回答1: Not sure about the up searching but as far as finding you can use something like this int selStart = ControltoSearch.SelectionStart; int selLength = ControltoSearch.SelectionLength; int newLength = SearchFor.Length; int newStart = searchIn.IndexOf(SearchFor, selStart + selLength, compareType); ControltoSearch.SelectionStart = newStart >= 0 ? newStart : 0; ControltoSearch

问题 I am new to cake and I am practicing with a twitter-like clone. At this point, I have 3 tables: users (id, name) id is the auto-generated id name of the user tweets (id, content, user_id) id is the auto-generated id content is the text of the tweet user_id is the id of the user that made the post followers (id, follower_id, following_id) id is the auto-generated id follower_id is the user who is doing the following following_id is the user that is being followed So, being new to sql as well,

问题 I have an hg repository and I would like to know the last commit date of every file in sources/php/dracca/endpoint/wiki/**/Wiki*.php So far, I have this one liner: find sources/php/dracca/endpoint/wiki/ -name "Wiki*.php" -exec hg log --limit 1 --template "{date|shortdate}" {} \; -exec echo {} \; But this seems utterly slow as (I suppose) find makes 1 hg call per file, leading to 15seconds of computation for the (say) ~40 files I have in there... Is there a faster way? The output of this

问题 I have a set of python files which make up a program for saving tidbits of info and searching them via tag association. I had the program working for many versions, but I recently made what I thought was a minor change that caused the program to go haywire. The ENTRY object is the basis of the data storage - it holds a unique ID number, a nickname, a value, and a list of tags. class ENTRY: def __init__(self, idNum, nickName, value, tagList): self.idNum = idNum self.nickName = nickName self

问题 Issue: I'm having to search a large sheet for specific policy numbers. The find function takes quite a while when there are nearly 75,000 rows. Any suggestions on how to compare these two sheets of 75,000 rows? A solution i thought might work would be to sort each sheet and then take the policy number needed to be found and compare it to the middle row. Is there a way to compare that policy number and see if in the simple sort function it would be greater or less than? After finding that

问题 Migrating about 200,000 files to OneDrive for business, and discovered that there are a few characters they don't like - the biggest offender is # . I have about 3,000 files with a hash, and I'd like to replace them all with just No. . For example, old: File#3.txt new: File No.3.txt I tried using a PowerShell script, but it doesn't like # either: Get-ChildItem -Filter "*#*" -Recurse | Rename-Item -NewName { $_.name -replace '#',' No. ' } I'm not having much luck figuring out the syntax for
