- 1. 3 Experiment 1.3 Student Name:JHA AMIT SUMAN UID:20BCA1066 Branch: UIC (BCA) Section/Group: 3/B Semester: 4th Date of Performance:18/03/2022 Subject Name: Linux Administration Lab Subject Code:22E-20CAP-256 1. Aim/Overview of the practical: a) Using the command like mkdir, touch etc. for file and directory creation. b) Using vi editor and script command for read and write in text files. 2. Task to be done: Task of Answer 1Using a single command, create the directory DIR1 and inside this create another directory DIR2 and inside DIR2 create directory DIR3. Show the path of the DIR3 directory. Now add a blank file named FILEDIR3 under a directory DIR3 and check whether the file got created or not. Now come out of directory DIR3 to DIR1 in a one go and try to remove a DIR1 along with its including directories and files. Task of Answer 2Create a blank file ABC.txt. Add the contents using vi-editor as follows “Have more than you show, Speak less than you know” By William Shakespeare Save and quit from the file. Create another file named DEF.txt and enter the content “HELLO, HOW R U?” in it. Now delete “R” and edit it as “ARE” and now move this file to another directory DIR1. At last append the contents of ABC.txt to DEF.txt. After appending store the contents in DEF.txt file as command to record script and at least 5 options to date command. 3. Concept Used: echo: to display text on screen within double quotes. mkdir -p: to create parent directory and within sub directories.
- 2. ls-R: to display files and sub files. cd: to change one to another directory. touch: to create files. cd ../.. : to go two directories back. pwd: to print working directory. rm -r: to delete parent + sub directories. Vi filename: to open file in vi editor. i(in vi editor): to enable insert mode. ESC(in vi editor): to enable command mode. %s/word/replace/g: to search a word and replace with another word. cat file1 >> file2: to append file1 into file2. script filename: to save commands as a script in a file. date: to get current date. date -u: to print date in UTC format. date “%D %T”: to print date and time. date –date=”value”: to print date of given value time. date “+%Y/%d/%t”: to print year date and time. 4. Steps/Commands involved to perform practical: Steps of Answer 1 Step 1. Use mkdir command with option -p with value of path to create sub directories. Step 2. Use cd command to change directory to DIR3. Step 3. Use ls with option -R to show recursive path. Step 4. Make a FILEDIR3 named file with the help of touch command. Step 5. Use ls to check whether file is created or not. Step 6. Use cd ../.. to go two directories back and can add more dots and forward slash in order go further back in directory. Step 7. Use rm with option -r and directory name to delete that directory recursively. Steps of Answer 2 Step 1. Use touch command to create an empty text file named ABC.txt. Step 2. Open the same text file in vi editor and enable insert mode in order to write given text. Then, just save the file with wq command. Step 3. Create another file in same manner and write text. If want to replace some word in vi editor use
- 3. %s/original word/new word/g. Step 4. Use the mv command to move text file to DIR directory. Step 5. Now, use cat command to append the data of one file to another. Step 6. At last, type script with given text file and hit enter. Then, use 5 different – different date Commands and type exit. 5. Result/Output/Writing Summary: Result of answer 1 Result of answer 2
- 8. Learning outcomes (What I have learnt): 1.Learnt how to perform basic commands in Linux. 2.What is file hierarchy in linux. 3.Learnt the use of vi editor in Linux. 4.Learnt the use of script command in Linux. 5.Learnt the text editing commands in vi editor.
