  5. This competition is only for 2nd year students of SVNIT and IIIT Surat. Rest can solve but their submissions won't be counted.

  9. Number in brackets after each problem statement specify the maximum points for solving that problem.

  10. UPDATE: Still stuck? don't worry you can submit till today midnight (7th September 2020, 11:59pm), but with -5 points penalty.

  11. UPDATE2: You can submit any number of times, the latest submission will be considered.

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. Your task is to prepend * in front of the given lines using vim. The answer will be evaluated on the basis of keystrokes used. If less keystrokes are used, you will get better score. (10)
