Lab 2: Bash Programming
Dear Script Programming Newbees
- I think the Docker experiment starts to exhaust your strength and intellect on finding a good solution
- Now you need to do more for your work
- When you start coding, basically you are bashing Perquisite: you installed VM with a Linux-kernel system Help docs for bashing:
- https://devhints.io/bash
- https://linuxconfig.org/bashscriptingtutorialforbeginners
- Our course has established a well-defined relationship with Baidu Inc. and Google Inc. For any of your questions, you can use their service to find out
Goal for Lab 2
- Objectives:
- To write shell scripts to solve problems
- To implement some standard Linux-kernel utilities such as ls,cp,etc using system calls.
- Understanding the idea of multi-programming (or multiplexing) and threading
- Learn to read an English poem
- Learn to read instructions, carefully
- Write a decent report
Use Bash for Shell scripts
- Write a Shell script that accepts a filename, starting and ending line numbers as arguments and displays all the lines between the given line numbers.
- Write a Shell script that deletes all lines containing a specified word in one or more files supplied as arguments to it.
- Write a Shell script that displays list of all the files in the current directory to which the user has read, Write and execute permissions.
- Write a Shell script that receives any number of file names as arguments checks if every argument supplied is a file or a directory and reports accordingly. Whenever the argument is a file, the number of lines on it is also reported.
- Write a Shell script that accepts a list of file names as its arguments, counts and reports the occurrence of each word that is present in the first argument file on other argument files.
- Write a Shell script to list all of the directory files in a directory
- Write a Shell script to find factorial of a given integer.
File to use in your Test Linux Poem: The Reentrant Kernel
By Morgan Phillips
| A reentrant function, if interrupted,will return a result,which is not perturbed.int global_int;int is_not_reentrant(int x) { int x = x; return global_int + x; },depends on a global variable,which may change during execution.int global_int;int is_reentrant(int x) { int saved = global_int; return saved + x; },mitigates external dependency,it is reentrant, though not thread safe. |
Save the poem as your text file
Now to Show it Off
- Instead of running basic bash coding solely, you need to exec it
- You need to write a control script (i.e., script for script) that execute all your previous bash code one by one in a certain order
- You need to append this piece of code to your report, as well as screen shot of running this code
- HINTS: bash allows multiplexing in executing certain codes, the specific cmd to run it is hidden in this page.
