Perform the following Tasks in a bash script:$1.$ find the number$/$count of words in dictionary.txt that have at least three as $($eg: bananaapparatus, madagascar, etc$).($case insensitive$)2.$ Next, Find the number $/$count of words in the dictionary that have exactly three $\text{'}$e$\text{'}$s and whereall $\text{'}$e$\text{'}$s are separated by at least one non$-\text{'}$e$\text{'}$ character. In other words, you should match a wordsuch as "serenely" $($as all three $\text{'}$e$\text{'}$s have at least one non$-\text{'}$e$\text{'}$ character separating them$)$ but youshould not match a word such as "beekeeper" $($as there are two adjacent $\text{'}$e$\text{'}$s that are not separatedby a non$-\text{'}$e$\text{'}$ character$).$ This is a little tricky as you need to consider that some words begin withan uppercase $\text{'}$E$\text{'}$ and regexes are case sensitive by default$\mathrm{.}3.$ Finally, find the three most common last three letters for words in dictionary.txt that have twoadjacent $\text{'}$e$\text{'}$s$.$ I recommend doing this in two steps:$3$a$.$ Find a list of all words in dictionary.txt that have two adjacent $\text{'}$e$\text{'}$s$.($The words canhave more than two $\text{'}$e$\text{'}$s as long as at least two of them are adjacent$)\mathrm{.}3$b$.$ Then find the three most common final three letters of these words. $($Hint: take a lookat how you might use grep to strip off the final three letters and how you might use sortand uniq to find the most frequent occurrences for a given set of data$)$
