match

问题 I want a regexp to match partial weekday names. For example, I want to match "Thursday", "thurs", "thur" or "Thu". I tried "thu(rsday)?", but that only matched "thu" and "thursday". The complete regular expression to match abbreviated weekdays would be excessively long. I tried this regex string: Mon(day)?|Tue(sday)?|Wed(nesday)?|Thu(rsday)?|Fri(day)?|Sat(urday)?|Sun(day)? The strings I have look like this: 3-Dec Mon 1:00pm Premiere USPHL Sk3-Red 4-Dec Tue 8:10pm U16 USPHL Sk3-Red 6-Dec Thur

问题 I must find in a file this string: 200 https://www.example.example The value 200 is randomic, I must find every HTTP return code (ex 200, 301, 404 etc...etc) How can I grep only this string with return code variable (I don't want specify every return code in grep command)? cat file.txt | grep "*** http*" But it doesn't work. 回答1: So you want to match any line starting with a three digit number, followed by "http"? grep -E '^[0-9]{3} http' file.txt More accurate as suggested by fedorqui

问题 I have two csv files each which contain ngrams that look like this: drinks while strutting,4,1.435486010883783160220299732E-8 and since that,6,4.306458032651349480660899195E-8 the state face,3,2.153229016325674740330449597E-8 It's a three word phrase followed by a frequency number followed by a relative frequency number. I want to write a script that finds the ngrams that are in both csv files, divides their relative frequencies, and prints them to a new csv file. I want it to find a match

问题 I currently have a score sheet with tons of rows/columns (product names are on the left, scorers are on the top, and scores are in each cell within this range). What I'm trying to do is create an export/snapshot of only a few of those rows & columns on another sheet in the same workbook. I'm trying to figure out the easiest way to refresh the scores in each of the cells on this worksheet, and so far have arrived at using Index/Match. I want to code it to make this process easy/automated.

问题 I have two data frames. One data frame ( Partners.Missing ) contains 195 people who are partnered (married, de facto, etc) for which I need to construct the partner, using a random selection from a second data frame ( NAsOnly ). The Partners.Missing data frame information is: str(Partners.Missing) 'data.frame': 195 obs. of 8 variables: $ V1 : Factor w/ 2 levels "Female","Male": 1 1 1 2 1 1 1 2 2 2 ... $ V2 : Factor w/ 9 levels "15 - 17 Years",..: 4 4 7 7 4 4 7 3 7 4 ... $ V3 : Factor w/ 1

问题 Please look the example sheet. The 'sheet1' is a gradually filled table. In column "A" some kind of ID for each entity. These identifiers are sometimes repeated. In the result I just want to know the appearance number of each ID. To solve this I created 'sheet2'. in 'sheet2' column 'A' list of unique values from 'sheet1'. Then with huge formula in cell 'sheet2!B2' I get all row numbers for each unique value from 'sheet1' separated by columns. And finally I want to get in 'sheet1' column

问题 For any input string, we need to find super string by word match in any order. i.e. all words in the input string has to occur in any order in output string. e.g. given data set: "string search" "java string search" "manual c string search equals" "java search code" "c java code search" ... input: "java search" output: 1) "java string search" 2) "java search code" 3) "c java code search" input: "search c" output: 1) "manual c string search equals" 2) "c java code search" This can be done in a

问题 i'm learning a new programming language, which is F# and I'm struggling to solve a method. I need to divide a list of movies and books into to 2 lists. One where the movies are and another one where the books are listed in. I can't use functions that already exists in F#. I link some exemples what i have done until now. Thank you in advance type Movie = { movieName: string duration: Nat fileSize: Nat } type Book = { bookName: string pages: Nat } type Activity = | Watch of Movie | Read of Book

问题 I am using this awk code to pick out an IP address in the /etc/hosts file and although I can force it to match the correct hostname, awk will select an "almost like" hostname if it see's it first. I have researched this and I cannot figure it out. sUSER=machine_005 ip=$(awk '/^[[:space:]]*($|#)/{next}/'$sUSER'/{print $1; exit}' /etc/hosts) I know the first part looks for $ or # and if found calls the next line. This feature is needed in the final formula. The other feature needed is to stop

问题 I'm using "Application.match" to find if Column AD of a sheet contains "1". But whenever I try to run my code, "Else" condition is always True. Although I'm expecting it to enter the "If" condition, since Column AD has a cell with a value "1". The values of the cells in Column AD are mostly results of a formula, except for AD1, which has the string "Check if Titile&Author Match", and AD2, which has the value "0". What is the problem. What is the solution for it? I hope you can suggest a
