📋 Complete Lab Plan

Sr. No.	Lab Number	Experiments
1	1-2	Use the touch command to create sets of empty practice files. Create six files with names of the form songX.mp3, snapX.jpg, filmX.avi. Create three subdirectories: friends, family, and work using a single command.
2	3-4	View the gedit man page. Use man -k ext4 to find the command to tune ext4 file-system parameters. Use brace expansion and wildcards for file matching. Explore cat, less, and more commands.
3	5-6	Use vim and nano to edit files. Use the lab_file shell variable. Enter visual mode in Vim, remove the last seven characters of the first column, and preserve only the first four characters.
4	7-8	Create the /home/consultants directory. Add write permission to the consultants group using symbolic method. Forbid access to others. Change the umask for operator1 user to prohibit all access for non-group users.
5	9-10	Implement ps, top, and kill commands with their options. Install, update, and remove software using apt-get.
6	11-12	Create the operator1 user and set the password. Add operator2 and operator3 users with passwords. Use usermod -c to update comments for operator1. Remove operator3 from the system.
7	13-14	Use chown and chmod commands with their options to modify ownership and permissions.
8	15-16	Write shell scripts to print system information and perform basic mathematical calculations. Use redirection operators to store command outputs.
9	17-18	Implement fdisk, parted, df, and du commands with their options for disk management.
10	19-20	Use rsync, tar, and compression commands to efficiently store and transfer files.
11	21-22	Configure system networking using netplan and nmcli. Set up and configure the system firewall.
12	23-24	Use top, htop, iostat, and vmstat to monitor system performance. Tune the system using sysctl and tuned. Perform log management and analysis using syslog and journalctl.
13	25-26	Execute ssh commands to securely access remote computers.
14	27-28	Run shell scripts to create functions and perform advanced string manipulations. Use cron and at commands to schedule future tasks.
15	29-30	Create and manage containers to create virtual machines on the system.
