It is false that it is not possible to open more than one file in Vim without running a second instance. Vim supports multiple buffers, windows, and tabs that allow you to work with multiple files within one Vim session. You can use various commands and options to open, switch, split, close, and manipulate files in different ways.

The program systemd is the process with process ID 1. It is responsible for initializing the system in the required way. systemd is started directly by the kernel and resists signal 9, which normally terminates processes. All other programs are either started directly by systemd or by one of its child processes.

The valid device types are character and block devices. Character devices are devices that transfer data byte by byte, such as keyboards, mice, terminals, etc. Block devices are devices that transfer data in fixed-size blocks, such as disks, CD-ROMs, etc. Pipe, null, redirect, udev, and network are not device types but rather concepts or components related to devices or device management.

When Bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

The first file executed by a bash login shell is /etc/profile. This file sets global environment variables and aliases for all users. It may also source other files in /etc/profile.d/ directory. References:https://documentation.suse.com/sles/15-SP3/html/SLES-all/cha-bash.html#sec-bash-startup

The /etc/fstab file contains information about file systems that need to be mounted at boot time or on demand. It specifies the device name, mount point, file system type, mount options, dump frequency, and fsck order for each file system.

To make the third menu entry of your GRUB2 boot menu your default menu selection, you need to do the following tasks:

• Edit the /etc/default/grub file and set GRUB_DEFAULT to 2
• Run the grub2-mkconfig command

The /etc/default/grub file contains various settings for the GRUB2 boot loader, such as the default menu entry, the timeout value, the theme file, etc. The GRUB_DEFAULT setting can be set to a numeric value that corresponds to the menu entry index (starting from 0), or a string value that matches the menu entry title. The grub2-mkconfig command will generate a new /boot/grub2/grub.cfg file based on the settings in /etc/default/grub and other configuration files and scripts.

The command that is used to ensure an ext3 file system is checked every 50 times it is mounted is tune2fs. The tune2fs command can be used to adjust various parameters of an ext2, ext3, or ext4 file system. The -c option can be used to set the maximum number of mounts between two file system checks. For example, tune2fs -c 50 /dev/sda1 will set the check interval to 50 mounts for /dev/sda1. References:https://documentation.suse.com/sles/15-SP3/html/SLES-all/sec-tune2fs.html

You can use getfacl ~/scripts/tstparse.sh to view the Extended ACL for the file. References:https://documentation.suse.com/sles/15-SP3/html/SLES-all/sec-acl.html#sec-acl-set
