LINUX FILE DETAILS HOW TO

You’ll see how to do it later in this article.Įven if you are the only user of the system, you’ll still be part of many groups. It saves time because instead of manually adding permission for each user, you can simply add them to a group and change the permission for the group. This way, you can manage files and security of the system effectively. A group consists of several users and this is one way to manage users in a multi-user environment.įor example, if you have dev team, QA team and sysadmin team accessing the same system, you should create separate groups for them. GroupĮvery user is part of a certain group(s). The ownership can be changed as well, but we’ll see that later. When you create a file, you become the owner of the file. I guess you know that directories are files anyway.Įvery file and directory in Linux has three kinds of owners: User Note: I might use the term file here but it is applicable to directories as well. Understanding file ownership and permission is crucial for a Linux user. Which file would be accessed by which user is decided by two factors in Linux: This ensures that a file or directory can be accessed, modified or executed by only desired users. This is why UNIX and thus Linux (Linux is a Unix-like system) has built-in security measure in place. But if any user could access and modify all files belonging to other users or system files, this would certainly be a security risk. In an enterprise system, there would be multiple users accessing the same system. The date and time when the file was last changed and saved.By design, Linux is a multi-user operating system. The date and time when the file was last opened. This is useful forĬhecking if the hard disk is full. Which is available on the disk that the folder is on. Of a list of the folders that you would need to go into to find the file.įor example, if Jim had a file called Resume.pdf in his Homeįolder, its parent folder would be /home/jim and its location This is a unique “address” of the file on your computer, made up The location of each file on your computer is given by its absolute

This is also an indicator of how long it will take to download a file or send it in an email (big files take longer to send/receive). The size of a file tells you how much disk space it takes up.

This field is displayed if you are looking at a file (not a folder). If the folder is empty, the contents will display nothing. If the folder includes other folders, each inner folder is counted as one item, even if it contains further items. It helps you see the number of items in the folder. This field is displayed if you are looking at the properties of a folder rather than a file. The MIME type of the file is shown in parentheses MIME type isĪ standard way that computers use to refer to the file type. For example, youĬan’t open a picture with a music player. The file type determines whichĪpplications can open the file, among other things.
