#Grep with regex how to
Python exercise showing how to graph all of the notes on a guitar. Netgear noticed the popularity of my XRAID/RAID calculator and asked me to help dev up the javascript logic. While employed at Netgear, I wrote the logic behind this calculator. Also for any ZFS volumes and any MDADM volumes: RAID0,1,10,50,60 with any number of vdevs (RAIDz3 not included). This calculator works for the ReadyNAS and ReadyDATA. Use this calculator to find final useable filesystem size of a RAID array. Mainly, it parses all of your orders and outputs sorted orders, open positions, informative profits, dividend information.
#Grep with regex code
Github code available inside.Ī robin_stocks API powered python script that parses your Robinhood account to provide you with all information in a single text output. Can view normal scale plot or logarithmic scale plots. In that case, more would be yellow or greenĪ python powered covid19 dashboard. So that means there is only 1 e in the thing. This is because WEAVE had 2 es, and the first e was yellow. The 3rd grep takes care of the letters that can’t be there, all of the grey letters. Note using “grep ” is wrong as it will just match an “e” or “t” or “h”, but we need it to match an “e” and a “t” and an “h”. We know that there should be an “e”, “t” and “h” somewhere. We could include the letter we know, “i”, but it wouldn’t change the answer. Specifically, the ones which we don’t know where they lay. The 2nd, 3rd and 4th grep repeats the letters from the 1st grep.
Also, some spots may have multiple letters that cannot be there: The 2nd spot, as an example, can’t be an “e” and can’t be “t”.Īlso the 1st grep takes care of the green, with the i. The 1st grep takes care of the yellows (its the right letter but its in the wrong spot). > cat WORDLE_ALLOWED.txt | grep 'i' | grep e | grep t | grep h | grep -v "" So next we know we need to try cense, conge or conte.įrom above’s set of given steps and their results, I would construct the following: > cat allowed_words.txt | grep "c.e" | grep "." | grep n | grep -v "" > cat allowed_words.txt | grep "c.e" | grep n | grep -v "" Here we can see the output of both commands is the same: The first and second grep can actually be meshed together, giving an end result like this: cat allowed_words.txt | grep "c.e" | grep n | grep -v "" To combine the cases we can pipe them together: cat allowed_words.txt | grep "c.e" | grep "." | grep n | grep -v "" Or combine them like this (note the order of a or r doesn’t matter) cat allowed_words.txt | grep -v "" So we can take care of that with this grep cat allowed_words.txt | grep -v "a" | grep -v "r" We know that we can’t have an “r” or an “a” anywhere. Now its looking for an “n”, that is not in the 4th slot. Or cat allowed_words.txt | grep "." | grep n To do that we pipe another grep cat allowed_words.txt | grep -v "." | grep n However, now we must make sure there is an “n” in there. Or cat allowed_words.txt | grep "."īut we are not done, that only takes care of an “n” not being the 4th slot. We know that we have an “n”, but it cant be in the fourth slot. We also know that those 3 dots, can’t be certain letters, and we will take care of that with case 2 and case 3, and when we pipe the greps together, we will get our desired end result. We know that a “c” and an “e” are in the first and last spot respectively.ĭot character means it can be any character. For simplicity, we will use standard grep. Sidenote: grep is not the only alternative for this. Note you will see that there are many ways to achieve the same result with grep. So we know there is an “n”, but it is not in the 4th slot.Ĭase 3. So we know there are a “c” and “e”, and they are in the right spot.Ĭase 2. So let us take care of the three cases: green, yellow, and grey.Ĭase 1. Grey means that letter doesn’t exist in the word. Yellow means that a letter exists in the word but it is in the wrong spot. We know that green means it’s the right letter and in the right spot. I can show you how to do everything you need to learn with one step of the game / one example. Fun fact, the creator of the game had his girlfriend or wife select which words. When wordle was created, they didn’t use all of the words. Note: there is a file called possible_words that has all of the English 5 letter words.
#Grep with regex download
Or just download the allowed_words file like this wget In his first iteration the best-started word for the game is “crane”, but his second video updates that to another word, “salet”.Īnyhow, download his latest wordle git to get the allowed words file git clone Youtuber 3b1b has created a python script analyzing the best words to start with. To cheat thru it with regex, first, get the allowed_words file. To learn how to play it just watch the first video link below. Wordle is an interesting 5 letter word puzzle game.
