To view the directory tree structure of a directory on a Linux machine, you can use the tree command. This command displays the contents of a directory in a tree-like format, showing the directory hierarchy.
To view the directory tree structure of a directory, you can use the following command:
tree <directory>
Replace <directory> with the name of the directory you want to view. If you omit the directory name, tree will display the directory tree structure of the current working directory.
For example, to view the directory tree structure of the /etc directory, you can use the following command:
tree /etc
This will display the directory tree structure of the /etc directory, showing all the subdirectories and files contained within it.
You can also use the -L option to specify the depth of the directory tree to display. For example, to display only the first level of the directory tree, you can use the following command:
tree -L 1 <directory>
You can also use the -d option to show only directories and not files, or the -f option to show the full pathname of each file.
For example, to show only directories and their names in the /etc directory, you can use the following command:
tree -d /etc
And to show the full pathname of each file in the /etc directory, you can use the following command:
tree -f /etc
