The correct command to change the quota for a specific user is edquota. This command allows you to edit the quota limits for a user, a group, or a file set. You can specify the name of the user that you want to edit the quotas for after the command. For example, to change the disk quota for user ‘linuxconfig’, you can use the following command:

sudo edquota -u linuxconfig

This command will open an editor with the current quota information for the user ‘linuxconfig’. You can modify the soft and hard limits for the block and inode usage as per your requirements. You can also use the -p option to copy the quota settings from another user. For example, to copy the quota settings from user ‘ramesh’ to user ‘linuxconfig’, you can use the following command:

sudo edquota -p ramesh -u linuxconfig

The other commands are not suitable for changing the quota for a specific user. The repquota command displays a summary of the current quota usage and limits for the users or groups. The quota -e command turns off the disk quota for the current user. The quota command shows the disk quota and usage for the current user or for the users specified on the command line. For more information on how to use disk quota on Linux, you can refer to the following articles:

The apt-get subcommand that installs the newest versions of all currently installed packages is dist-upgrade. The dist-upgrade subcommand performs the same function as the upgrade subcommand, which is to install the latest versions of the packages that are already installed on the system, but it also intelligently handles the dependencies and removes the obsolete packages if necessary. The dist-upgrade subcommand is useful when upgrading the entire system to a new release or distribution12.

The other options are either invalid or do not perform the desired task. The auto-update subcommand does not exist, and the update subcommand only updates the list of available packages from the repositories, but does not install any packages. The full-upgrade subcommand is an alias for the dist-upgrade subcommand, so it performs the same function, but it is not the standard name for the subcommand. The install subcommand installs new packages or specific versions of packages, but it does not upgrade all the currently installed packages. References:

The i and a commands are two of the most commonly used commands in the vi editor to enter the insert mode. The insert mode allows the user to insert text into the file. The difference between the i and a commands is that the i command inserts text before the current cursor position, while the a command inserts text after the cursor position. For example, if the cursor is on the letter “e” in the word “editor”, then pressing i will allow the user to insert text before the “e”, while pressing a will allow the user to insert text after the “e”. The user can exit the insert mode by pressing the Esc key, which will return to the command mode. References:
