List of Experiments:-
1. To Study basic & User status Unix/Linux Commands.
2. Study & use of commands for performing arithmetic operations with Unix/Linux.
3. Create a file called wlcc.txt with some lines and display how many lines, words and
characters are present in that file.
4. Append ten more simple lines to the wlcc.txt file created above and split the
appended file into 3 parts. What will be the names of these split files? Display the
contents of each of these files.
How many lines will be there on the last file?
5. Given two files each of which contains names of students. Create a program to
display only those names that are found on both the files.
6. Create a program to find out the inode number of any desired file.
7. Study & use of the Command for changing file permissions.
8. Write a pipeline of commands, which displays on the monitor as well as saves the
information about the number of users using the system at present on a file called
usere.ux.
9. Execute shell commands through vi editor.
10. Installation, Configuration & Customizations of Unix/Linux.
11. Write a shell script that accepts any number of arguments and prints them in the
reverse order.
12. Write a shell script to find the smallest of three numbers that are read from the
keyboard.
13. Write a shell script that reports the logging in of a specified user within one minute
after he/she logs in. The script automatically terminates if the specified user does not
login during a specified period of time.
14. Installation of SAMBA, APACHE, TOMCAT.
15. Implementation of DNS, LDAP services,
16. Study & installation of Firewall & Proxy server
