If you want to get the results in the reverse sort order, use the -r option.įor example, to sort the files in the /var directory by modification time in the reverse sort order you would use: ls -ltr /var -sort=version (or -v) - Natural sort of version numbers.-sort=time ( or -t) - sort by modification time.-sort=size (or -S) - sort by file size.-sort=extension (or -X ) - sort alphabetically by extension.The -sort option allows you to sort the output by extension, size, time and version: bash_historyĭrwxr-xr-x 2 linuxize linuxize 4096 DesktopĪs we already mentioned, by default, the ls command is listing the files in alphabetical order.

You can change the file owner using the chown Use the -h option if you want to print sizes in a human-readable format. The next two fields root root are showing the file owner and the group, followed by the size of the file ( 337), shown in bytes. The number 1 after the permission characters is the number of hard links to this file. In our example, rw-r-r- means that the user can read and write the file, and the group and others can only read the file. The permission character can take the following value: You can change the file permissions with the chmodĬommand. The first three characters are for the user, the next three are for the group, and the last three are for others. The next nine characters are showing the file permissions. Values for other file types are as follows: In this example, the first character is -, which indicates a regular file. Let’s explain the most important columns of the output. Here is an example: ls -l /etc/hosts -rw-r-r- 1 root root 337 Oct 4 11:31 /etc/hosts When the long listing format is used, you can see the following file information: The -l ( lowercase L) option tells ls to print files in a long listing format.

The files are listed in alphabetical order in as many columns as can fit across your terminal: cache db empty games lib local lock log mail opt run spool tmp When used with no options and arguments, ls displays a list of the names of all files in the current working directory
