The file /usr/share/dict/words holds a list of English words. We want to use egrep to display only those which match the following rules;  The word has tow or more quote symbol ‘ in it Each quote symbol is followed by one or more character The word should not start with a quote symbol ‘ In addition; we are working with Ubuntu Linux on the bash shell using GNU egrep tool Here are some examples of the words which will be matched; bo’s’n bo’s’n’s bo’s’ns Which of the following is the best solution?

Consider the following data files:  digits-en.txtThis file contains digits (0 to 9) and their lower-case spelling in English.Example of contents: nine 9two 2one 1four 4 digits-fr.txtThis file contains similar information, but the digit comes first and the words are in French (without accentuated letters, to make things easier).Example of contents: 8 huit3 trois4 quatre1 un digits.txtThis file contains only numbers.Example of contents: 354298 Please note the following:  Our files may not all feature the same numbers. We will therefore have the spelling for some numbers in only one language, in both, or in none. None of the files are to be assumed to be already sorted by numbers. A single space is used as separator in all files. We want to display the following: Sorted list of all numbers that have an English spelling in our files. Sorted list of all numbers that have only a French spelling in our files. Sorted list of all numbers that have a spelling in only one of the two languages.

We have a plain-text file named persons-of-interest.txt. It contains several fields, each separated from the next by a single space. Within each field, no space character is used. The first field is a first name, the 2nd a last name, and the 3rd an optional variable-length integer called the Jedi Extensive Directory Identifier (J.E.D.I.).  Another file, named mc.txt contains only two fields. The first one is a J.E.D.I. number, and the second a decimal number representing the midi-chlorian count of the corresponding individual.  Provide command lines allowing us to display only the last name and midi-chlorian count of any individual who has a J.E.D.I. number.   Provide another command line allowing us to display only the first and last name of anyone who does not have a J.E.D.I. number.

I certify that every single work I will submit to be graded in this course will be solely the result of my personal work and knowledge. More specifically, I will not seek help from anyone but the instructor of this course. I will also not use material of any form found on the web without first making sure the instructor authorizes me to do so explicitly in writing; e.g. email.
