Be sure to observe that the output you get when running the ls command thereafter, will be as though you run the ls -l command. What this does is that it tells the system to execute the ls -l command instead of the ls command. We can create an alias for the ls command this way Syntax $ alias='ls -l' If you want to display the UID as well as the GId of files and directories, append the -n parameter as shown Syntax $ ls -nĪliases are customized or modified commands in Linux shell which are used in the place of the original commands. To display the inode number of files and directories, append the -i flag at the end of the ls command as shown Syntax $ ls -iĭisplaying the UID & GID of files and directories Syntax $ ls -Fĭisplaying the inode number of files and directories If you wish to go ahead and further distinguish files from folders, use the -F flag such that folder will appear with a forward slash character ‘/’ at the end. Listing files and directories with the ‘/’ character at the end To display the directory tree of files and folders use the ls -R command as shown Syntax $ ls -R

Hidden files are usually system files that begin with a full stop or a period. You can view hidden files by appending the -a flag. To easily identify the file sizes as kilobytes (kB), Megabytes (MB) or Gigabytes (GB), append the -lh flag as shown Syntax $ ls -lh Syntax $ ls -lĪs you may have noticed, the file and folder sizes displayed are not easy to decipher and make sense of at first glance.

Using the -l flag, you can list the permissions of the files and directories as well as other attributes such as folder names, file and directory sizes, and modified date and time.

Listing file and directory permissions with -l option To list files in reverse order, append the -r flag as shown Syntax $ ls -rĪs you can see above, the order of the listing has changed from the last to the first in comparison to the previous image. The ls command without any options lists files and directories in a plain format without displaying much information like file types, permissions, modified date and time to mention just but a few. Listing Files with ls command without any arguments In this guide, we will discuss Common ls commands in Linux and other parameters as well that may be used alongside the command. The command is used in listing contents inside a directory and is one of the few commands beginners learn from the onset. The output in this example shows that the smallest UID a normal user can receive is 1000, and the largest is 60000.The ls command is one of the most commonly used commands in daily Linux/UNIX operations. To check the UID range for normal users, use the grep command to search for the information stored in /etc/fs: grep -E '^UID_MIN|^UID_MAX' /etc/fs Normal users typically receive UIDs from 1000 onwards, with each newly created user receiving the next smallest unused UID. System users have UIDs in the range from 0 ( root user) to 999. Each normal user has a login shell and a home directory to store their files.īoth system and normal users in Linux have a unique user ID (UID) to identify them. Normal users are human users created by root or another user with root privileges.The most important system user is root, which possesses administrative privileges. System users are entities created by the system to run non-interactive processes, i.e., the processes that run in the background and do not require human interaction.Linux-based systems have two types of users - system and normal users.
