In Red Hat Enterprise Linux (RHEL) 8, managing directories is an essential part of file system navigation and organization. Sometimes, you may need to list directories within a specific location and move them to another directory for better organization or management. This article outlines the steps to achieve that.
Problem Scenario
To effectively manage directories in RHEL 8, you might need to execute commands that list all directories in a specified path and then move them to a different location. Here’s an example of the original problem code snippet that needs clarification:
ls -d */ && mv * /new/location/
Understanding the Problem
The original code attempts to list all directories with ls -d */, which is correct. However, the second command mv * /new/location/ tries to move all files and directories in the current directory, not just the directories listed in the first command. This can lead to unwanted files being moved as well.
Corrected Command
To correctly list the directories and move only those to another location, you can modify the command as follows:
# List all directories
ls -d */
# Move all directories to a new location
mv */ /new/location/
Breakdown of the Commands
-
List Directories:
ls -d */lists all directories in the current directory. The*/pattern ensures that only directories are displayed, filtering out any files.
-
Move Directories:
mv */ /new/location/moves all directories listed by the previous command to the specified path (/new/location/). The*/pattern again ensures only directories are moved.
Practical Example
Let’s say you are in your home directory and you have the following directories:
- Documents
- Downloads
- Pictures
- Music
If you want to move all these directories to /backup/, you would run:
# List directories
ls -d */
# Move directories to backup
mv */ /backup/
After executing these commands, all directories will be moved to the /backup/ directory, leaving your home directory clean and organized.
Additional Considerations
When using the mv command, be cautious of the following:
- Permissions: Ensure you have the necessary permissions to move the directories. You may need to use
sudoif the destination requires elevated privileges. - Existing Data: If the destination directory already contains directories with the same names, the
mvcommand will overwrite them. Make sure to back up any important data. - Wildcards: Be careful when using wildcards with
mv. To avoid unintentional moves, always double-check your command before execution.

Conclusion
Listing and moving directories in RHEL 8 is a straightforward task when using the appropriate commands. By employing ls to list directories and mv to move them, you can manage your file system efficiently. Always remember to verify your commands to avoid unintended consequences. Happy organizing!
