Question
Use a command to sort temp2.txt , remove duplicate lines, and save the result in output.txt .Describe what this file now contains.
Solution
To sort temp2.txt, remove duplicate lines, and save the result in output.txt, you can use the sort and uniq commands in Unix/Linux. Here are the steps:
-
Open your terminal.
-
Navigate to the directory where
temp2.txtis located using thecdcommand. -
Use the following command to sort
temp2.txt, remove duplicate lines, and save the result inoutput.txt:
sort temp2.txt | uniq > output.txt
This command works as follows:
-
sort temp2.txtsorts the lines intemp2.txtin lexicographical order. -
The
|(pipe) operator sends the output ofsort temp2.txtas input to the next command. -
uniqremoves duplicate lines from its input. -
> output.txtredirects the output of the previous command (i.e., the sorted, unique lines) tooutput.txt. Ifoutput.txtalready exists, this will overwrite it; if it doesn't exist, this will create it.
After running this command, output.txt will contain the sorted, unique lines from temp2.txt.

SortWrite a Python program that sorts all lines alphabetically within a text file.The program will be given 2 command line arguments: the first specifies the path to the file to sort, and the second specifies the column number to use as the key for sorting the file.Columns are numbered starting from 1. You can assume columns in the file are separated by a space " ", and that the column number provided is a valid column in the file.If the value in one column is a duplicate, the program sorts the lines with the duplicate value in alphabetical order based on the contents of their entire lines from start to finish.You should write your solution in sort.py.Example output$ cat students.txtMicheline Lalevee [email protected] USYDRobyn Maes [email protected] USYDVenus Kinsley [email protected] USYDDevonne Berrygun [email protected] UNSWLuci Broad [email protected] UTSMorissa Bolino [email protected] MacquarieDanika Heatley [email protected] WSURichmond Goodnow [email protected] USYD$ python3 sort.py students.txt 2Devonne Berrygun [email protected] UNSWMorissa Bolino [email protected] MacquarieLuci Broad [email protected] UTSRichmond Goodnow [email protected] USYDDanika Heatley [email protected] WSUVenus Kinsley [email protected] USYDMicheline Lalevee [email protected] USYDRobyn Maes [email protected] USYDError handlingIf the user does not provide exactly 2 command line arguments, print Error: must provide exactly 2 arguments to stderr, and exit the programIf the file does not exist, print Error: '<filename>' cannot be found to stderr, and exit the programYou may assume that all files provided to the program are valid text files, and the user has read permissions on all input files.Note: Your coding style will be examined, so take this into consideration for your solution.Be careful when sorting a column with numbers – sorting numbers alphabetically is different to sorting numbers numerically!You may only use the sys module – no other imports are allowed for this task.

Open the file romeo.txt and read it line by line. For each line, split the line into a list of words using the split() method. The program should build a list of words. For each word on each line check to see if the word is already in the list and if not append it to the list. When the program completes, sort and print the resulting words in python sort() order as shown in the desired output.
