CLI: 60 Points

For all the questions, assume that your are starting from the question directory q-xx.

1. Copy all the files from cli/q-01/from to cli/q-01/to. (2)

2. So, sudo is used to run commands in super user mode. Figure out a way to use please instead of sudo. So, if $ sudo xyz works, $ please xyz should works as well. (5)

3. cli/q-03 has a lot of files written in UTF-8. Write all the file names which contain the string "acm". (5)

4. cli/q-04/main.cpp contains a simple hello world program. Compile it to a binary called hello-world. Now to run this from say cli directory, I need to specify the whole path: $ ./q-04/hello-world. Figure out a way to run it from any location by entering just $ hello-world in the command line. (10)

5. cli/q-05 contains some old blurry images. Add prefix of old- to all the image files. You cannot use the rename command. (10)

6. cli/q-06/script.py contains the script we used to generate random files for question 3. Execute this script without using the python command. (5)

7. cli/q-07 contains file.c. Delete all the lines that contains the word "struct". (5)

8. cli/q-08 contains a lot of c++, java and javascript files. Calculate the number of lines of code of each of the 3 languages. (10)

9. cli/q-09 contains a linked list implementation written in java. Unfortunately, the code is in the reverse order. Fix it! (8)

VIM: 40 Points

1. Given the name and number of fruits available. Your task is to sort the file so that the fruit having maximum number is first. (10)
